Today on Sam's Trains: Sam builds his own variant of a Cog/Rack engine and tests the pants off of it! In all seriousness great vid! Cool concept and I look forward to the (eventual) version 2! Cheers, The Duke of Rawsome
@@SamsTrains Er, the sleepers are the rack. The only reason Pete didn't climb 45° is that the pins on the chain did not properly engage the sleepers. If they did, then clearly, the 45° incline would not have been an issue.
Great concept. Would have been more relevant with wheels something like the Zugspitzbahn or the narrow gauge that runs from Lauterbrunnen to Wengen in Switzerland. Fleischmann makes a gear rack that fits in between HO rails (art # 6412, retails at € 5.90). They also make a 2-6-0T locomotive (Art. # 4034 ) that will use the rack. (Do not have current price and availability on the locomotive.)
This is fascinating stuff. If you can just make the chassis a little bit narrower, you could probably get someone to 3D print a body for it, and you could add a new mountainside railway to your attic, akin to culdee fell or Snowdon.
Torpedo try n scale and buy a lot or 2 on eBay not every layout has expensive buildings and detailed grass and things like that, if you just make a layout that goes from room to room in a circle than that can look amazing and it will look nice and the track can fit under a closed door so yea if you want to use that advice you can
@@torpedo996 Firstly, you have to find a way to save up your money to afford it. Second, if you really don't have space, you can get T gauge which is the smallest model railway scale available. You have to be REALLY careful though because of the size, they can easily get lost and leave you searching for hours or even days to find it. The scale is 1:450 and the track gauge is 3mm so that should suit your needs. If you have shelves, use them to your advantage. If it's wide enough, you can probably fit a TT gauge (tabletop gauge) or if you're lucky, you can fit a simple HO/OO layout. If you have a backyard, use that to your advantage and get G scale (Garden scale)
Move the motor up front to tip the balance in its favor and you'll pull even steeper hills. What's happening now is the torque is exceeding the weight of the nose. Moving the center of gravity forward will improve traction and ability to pull up hills like that. Also, adding more nose weight will do, which is why I suggest moving the motor up front. Also, take some of that chain slack out. Interesting build.
Look up cog railroad. They can go up some pretty steep angles. There's one at Pike's Peak in Colorado. That's basically what you've built but they have a third cog rail which meshes with a drive gear on the locomotive.
This has to be one of the funniest videos you have ever made Sam! Even Gordon's Hill, the Evening Star loco and a 45 degree plank had to succumb to Speedy Pete! Poor Bullman too! Keep going Sam!
Sam, at this point you are building your own steam team. Let's have a video where you make a layout for your experimental team, for instance, there could be a really long siding for the endurance engine, an underwater section for the southern engine that you put in water, a steep hill for speedy pete, and banked curves for the propeller engine, adding another feature for every experiment video.
Based on the Rack & pinion systems seen on some of the World's steepest gradients Sam. Congratulations on achieving such an immensely powerful 00 Gauge loco..Full marks to your ingenuity on this one.
I used a San Francisco cable car Bachmann and mounted a neodymium 20 mm x 15 mm x 5 mm, placed it onto the an ho track with a metal ruler under the ties . It climbed easily up to 25 degrees but then started to slip, perhaps another magnet would improve the attraction and would increase the angle but I only need max 15 degrees.
That engine looks like a combination of a drag racer and a WW1 tank with tracks the same size as the tank itself. Speed is closer to those tanks, though.
Yes SAM, what an amazing video. You are so good at presenting model railways, that you should be on TV to mesmerise the people of this world. You are a true engineer and inventor, and a true HERO of model railways. I SALUTE YOU. Keep them coming, please.
It would be worth trying with some of the old triang locomotives. They weigh a bit and some are also fitted with magnetic tyres! Be interesting to compare against their modern counterparts.
Love the channel. Don't try the wall or upside down, as Tyco and others have you beat, however, I did find out that I have 6 locomotives,(Out of 23.), that will run through an HO lake. All but one are modern HO models with high efficiency motors, the other locomotives are old school Athearn, Mantua, Bachmann, Model Power, Rivarossi, Atlas, etc. The one exception was a Lionel GP-9 which has a high efficiency 5 Pole GE motor, all gear drive, and all wheels are driven and pick up power.(Not all of my locomotives are so well equipped.). The 50 year old model Geep, in normal daily service, ran through the water like it wasn't there, while 3/4 of my fleet stalled and made bubbles from the wheels and funny noises from the locomotive. I also have to give kudos to my treasured Atlas SD-24,(Original.), as I thought it was stalling, it was actually still moving, just slowly, and made it across the lake also. P.S. I think you should make either the infamous 0-2-0 (0-1-0 for you.) steam switcher locomotive, or the mighty 2-4+6+8-0 steam road locomotive.(1-2+3+4-0) or (1-Bo+Co+Do-0). This might be the contender you need to challenge Speedy Pete. P.S. My most powerful model, no traction tires, (Or chains!), has 6 ounces of pull.(Newtons please, probably a lot like your mid level diesel locomotives you tested.). I also run my trains outside, which gives them some nice, effective, realistic weathering. Keep up on the excellent train videos and "Goot jop, mi poy." ♡ T.E.N.
Thanks very much for the comment - Tyco have done that have they?! I have to see that! Thanks for this anyway - that all sounds good, well worth looking into that a bit more!! :D Thanks for watching - Sam :)
The strongest commercialised locomotives in HO might be the HOm ( HO for 1:87 and m for 1 meter gauge ) rack locomotives ( if you use the rack system ). I have a section of rack railway on my layout and it’s very impressive to see a long rack of coach going uphill with only one locomotive on a slope that normal locomotives in HO wouldn’t be able to manage
Thanks very much for this - I'll be sure to look that up! I wonder how much force they can withstand before the gears slip or break?? Thanks for watching - Sam :)
Sam'sTrains You have to add some more weight to the original model to pull heavy trains ( look at the FO HGe 4/4 37 on my channel to see one working hard going uphill) ;-)
If it can win a tug a war vs a tractor or a real train, then thats what you call HORSE POWER (Im American so I don't know if thats what they say in the UK) Also can I just say 13:00 is a bit insane
Actually, it's not HP it's torque. You can use a clock motor to pull a tractor trailer (real size) if you have low enough gearing. But it will take forever to move a foot. That's why Speedy Pete is so slow. High motor RPM to low output shaft ratio increases torque but reduces speed. Same is going on in your automotive transmission. First gear the motor spins a lot but the wheels don't spin fast. Lots of acceleration and pulling power but low speed. Second gear comes in at a lower gear ratio. You get more speed less torque. Third gear (or 1 to 1) is your highway gear (talking three speed transmissions) where the engine is turning the driveshaft at a 1 to 1 ratio. The only gear reduction after that point is the rear end ring and pinion gears. Typically 3.75 to 1 and 4.1 to 1.
For a second I thought you were gonna do an upgraded version of Gordon's hill but its just a steep climb for your experiment for how strong Speedy Pete is pulling Bullman around. I loved the name Speedy Pete BTW Lol. XD
A idea for a train build, make a fully solar powered train. Might need a cheap DMU of some sort possibly the budget Hitachi high speed train hornby made which was in the blue rapier set.
Part of the problem is it needs to take up the slack in the chain with a tensioner (like in the timing chains in an internal combustion engine) and a chain guide. The second problem is the little pins aren’t wide enough, and there’s not enough of them. Finally, ditch the chain and 3D print a sprocket for the motor whose teeth will fit in the gaps between the sleepers (ties.) You’ll have to find a machinist’s handbook to get the equations for making a sprocket/gear, but this will be a much better solution than a train that doubles as a chainsaw. 😂 Just make sure to make the width of the sprocket teeth just slightly narrower than the gap between the rails by - say - 1 millimeter or so on each side. Now you’ll have a right-and-proper cog railway… once you fit some bogies with power pickup!
This reminds me of when my dad used to go spotting at Nottingham in the 80s. He would see a class 56 with about 40 HAAs it would set off, the front of the train would be doing around 2mph and the back would still be stationary! It let off such a bang when they all finally started moving. Great video Sam!
If you were to ever reapproach this experiment, I think something worth trying to solve the issue of how finicky the pickups are for power would be to put the pickups on the inside of the track (so between the rails), another option would be to use a set of wheels with pickups from a preexisting model and attach them to Pete, but that also creates a problem of how would the chain work if its being obstructed by wheel. Nevertheless, a very interesting experiment!
Yeah this is very true - though it works much better without the insane load - it only starts to cut out with all the coaches and an incline! I had thought about it though - I may just wire a wagon onto the back of it, and let that do some picking up too! Thanks for watching - Sam :)
Love your wacky hot glued together experiments, just imagine how well they'd perform if you spent more time on their construction :) Very entertaining as usual Sam - great work!
6 newtons is around 0,6 kg of weight you could pull vertically (including the loco weight) and you could measure how much drag your couches procuce by pulling on them with that newton force scale by hand untill the last one moves i am interested in how much force it actually takes to pull all of those on video
Yes you could indeed - I didn't think to try that actually, but it would be interesting indeed! The Vi-trains 37 could move them too - so we know it's less than 3N, or whatever it was! Thanks for watching - Sam :)
I know this is an old video, but do UP Big Boy in Ho Scale. You can pre-order one from Hornby/UK because Hornby/US kind of sucks. But it is a company from the Uk
This is definitely a fascinating video, Sam! I'd wager a few quid that my Broadway Limited Imports HO Scale Big Boy would be a great contender for a pulling contest. For some quick context, the engine has four traction tires, and weighs in at a little over 2 pounds without his tender! Given all the bells and whistles he has (die-cast parts, smoke, lights, DCC, Sound), I'm surprised that I haven't tried to see his limits (probably because he's just a giant locomotive that barely fits on my workbench and I don't even have space for anything else when he's on one track). The other part to it is realism when it comes to strength. I am one of the modellers that would rather see a relatively realistic rake of rolling stock (depending on the engine) behind the bunker and/or tender while the engine is at speed or marshalling about the yard. A great video nonetheless!
Thanks a lot Hank - it would be great to try a big boy against this!! Ooh if it has tyres, then Pete might be in trouble! ;D Thanks for watching - Sam :)
Did Pete have any wheels at all? i didnt see any, maybe mounting the setup on a small chassis but using the same method of propulsion would aid it's pulling/ climbing power. Its a good idea though using a kind of Rack rail similar to mountain railways, i think with a little tweaking Pete could make that 45 angle.Maybe you could make a smaller version and mount it inside the body of a model, so it would look like a normal loco (ish) but with far increased pulling power. Maybe you could do a short video on Pete and how to make one?
haha nope - no wheels at all! Yeah it probably would have less friction if it were on wheels - but with all that power, I thought the friction caused by no wheels would be negligible! Thanks for watching - Sam :)
sam, you are an absolute mad lad!!! something could have gone wrong! train could have exploded but thats absolutley crazy!!! amazing homemade "locomotive"!!!
You have done a chain train, now how about a upside down train. You will need a length of steel track mounted upside down, a loco and coaches with steel wheels with strong magnets between the wheels in the fashion of triangs magnadesion, has this been tried before? If it hasn't I'll be looking forward to your video.
haha yes that would be the real challenge - I'd love to try that! Super-magnadesion would probably be a good way to go, you're right! :D Thanks for watching - Sam :)
So this time, you built an OO gauge experimental quasi-funicular loco. Might be interesting to see what happens if you build an *actual* funicular setup, with a suitably long length of bicycle chain. That's a setup that could haul Bullman AND a house brick on wheels I reckon ... :D
Sam many thanks for the ideas Spedy Peter is divine and with a few minor changes and tunings you get him to climb a wall, continue to develop your imagination and build some more prototypes a hug
haha thanks Gabriel - glad you found him divine, lol! I like the idea of developing him to climb 90 degrees, that'd be awesome! :D Thanks for watching - Sam :)
the fact this train can somewhat manage a 45-degree angle is pretty awesome. as mechanical speaking 46 degrees is the steepest natural stable angle you can get in nature (I am aware you can do 50 and up but those hills start getting landslide issues which also aren't used in construction 45 is when it comes to embankments)
Haha that water experiment reminds me of the work the late David Mitton did for the Thomas series, Percy's Promise was just that on Gauge 1/G scale and brown food dye to make the water look muddy. Granted they could of been using trollys that were from Mitton's Tugs but I have no clue.
There are trains build for climbing steep hills, even under steam power, you find them in places like Switzerland, Austria etc. The Germans call them "zahnradbahn", which means something like cogwheel trains. Here are working models made of this system, available in HO witch has the same track width as OO. They can pull up even steeper angels, but it's a fun trail…
I have been looking for a vlog I saw many years ago. I forget what club was involved but they were trying to set a record length train, I think it was HO scale. They had problems with one curve because of derailing. Then they added a DPU in the middle and solved the derailment but I don't remember if that nullified their chance at the record
Was it the Airfix 31 or the Mainline 56 set a record years back , traction tyres though. Also track on carpet , disclaimer about furring up locos , as a student I used to fix so many friends trains that were furred up. Surprised over the Heljan comment. Yes the Clayton's were a disaster but with over 150 Heljan locos I have found then robust and reliable , unlike Vitrains!
I have videos of the legend that is an Airfix 31 pulling and incredible length of wagons on my channel. Also the Airfix Royal scots (6 wheel traction tyres tender drive) have a huge haulage capacity. I have also done tests with these
Thanks Paul - yes the Airfix 31s and Mainline 56s are pretty strong things! No issues whatsoever running on carpet, as long as proper cleaning and maintenance takes place - my 400 odd engines are all in perfect working order! I must have been very unlucky with my Heljan engines then - I find almost all of them to be of dreadfully poor quality and design - most being pretty unserviceable too! Thanks for watching - Sam :)
@@SamsTrains In preparation for an exhibition were my stock will run the club layout I recently had to review my stock. It now appears my total collection , OO and some HO is just over 1500 locos. 90% are super detail DCC stock and by far the worst are Hornby. I haven't had expanding chassis in either Hornby , Bachmann or Heljan but with Hornby I have had broken cardigan shafts , broken wiring , mis fitting contact strips and my big bugbear on Hornby 60s the swinging close coupling that needs to be so well lubricated so it doesn't through even heavy freight stock off when reversing into a siding. Make you appreciate the days when once you had detailed a Lime diesel and added extra pick ups it would easily run for a year without needing attention.
Yet another unique and amazing science experiment. The way you coupled all the coaches around the entire track reminds me of that Adventure Time episode with that dungeon train going in an infinite loop with every coach coupled around the entire track.
Kind of reminds me off the cog and rack style locos, but since it doesn’t use the rails for traction and uses its “chain/track” would it be considered a more of a tank ?
Interesting experiment. Here is your stopping problem cause: you are using a metal chain in between the two power rails. Once it gets a little crooked it touches both rails and makes a short, stopping the power from the rails. Also your power pick up is super poor and cooper,brass track tarnishes very easily making poor contact. Use 4 unique plastic rollers that will roll on the inside edge of the rails and keep the chain drive centered and away from the track. Use 4 or more power pickups with some light spring action and you should be able to pull all of those cars around your track as long as the center is clear, no switches, no re-railers. Other options; use a plastic chain, make sure your cleats poke through between each of the ties (sleepers) smoothly like a gear would fit, just a matter of picking the right spacing to put a cleat, or better yet put the cleat (hard wire) on the outer link plate instead of the center pin, that will make spacing matching easier.
Thanks a lot for the thoughts - definitely no shorts going on though, since the controller would display as such, you're probably right about the poor pickups though! Thanks for watching - Sam :)
There is a cog railway system from Fleischmann with a couple of loco models, I used to have that when I started out on the hobby. I remember that it could do really stupid angles as well, but used a 1:2 gradient, which is 22,5° or a 50% gradient. A cog engine is always suposed to push the coaches up the hill for safety reasons, but that didn't really work in model as my curves were too tight and buffers catched. So I had my cog loco pulling the train and sometimes it did uncouple, leaving the train running down the incline, derailing and smacking against the rock face just off the tunnel portal. So I wrecked several quite expensive Fleischman coaches, and on the next layout there never has been a cog railway. I have some continental Roco Co-Co locomotives which have good pulling power, equal to the Vitrains, but my strongest loco I once built was a Garratt steam loco in Ho which could pull over 150 wagons, which was full circle on a large club layout. it finaly pulled one of the blades from a point when the train derailed and got stuck behind the platform end
I've been hearing about that Tom - I wonder how much force they can muster? Blimey, sorry to hear it wrecked a lot of coaches though, haha! Thanks for all the info, Cheers, Sam :)
I can see it coming to Sam, a special purpose built roller coaster with perhaps a Deltic with Pullman coach themed OO loop a looping thrill ride? Years ago I was in charge of the train set in a video store where we sold Video Camera's pointing at a layout and I thought wouldn't it be fun? My boss took the train layout before I wrecked it and gave it to a local children's home and bought some giant Disney animations instead and he did not speak to me for a few hours! Well, I was the one who had to clean the track every morning and was bored silly. Great videos and wondering what's next for Sam's Trains?
That'd be fantastic Ian - I do hope to create a loop for model trains one day, haha! Awhh sorry to hear he ruined your fun, haha! Thanks for watching - Sam :)
I've only just caught up with this video. I enjoyed it a lot. You'll be too young to remember this but Hornby Dublo used to stress how powerful their Co-Bo diesel was in magazine advertising. They set up a test track with a trolley on it carrying a young lady. The combined weight was, if I recall correctly,11 stones. Three Co-Bo's managed to pull it.
Pete would be an excellent shunting engine, I reckon. Sir Sam T. Rains of the Loft Railway's third class of locomotive if I'm correct. Also this sound: 14:48 I live for this sound now.
haha he certainly would - though his slow speed would probably be quite annoying! haha - lots of people like my sheep sound! ;D Thanks for watching - Sam :)
Now here's a challenge, make the Heljan Tango a good model! Also, getting a Hornby Duchess Of Sutherland train-pack with her mainline Support Coach for my Birthday next Sunday, which I may also see at the Mid Norfolk Railway too.

Place the chain in the middle of the tracks and let the motor drive the sprocket that is in contact with the chain and thus drive the motor. This type of drive is counterintuitively often used in the mountains and such a railroad is called a rack railroad

All but one are modern HO models with high efficiency motors, the other locomotives are old school Athearn, Mantua, Bachmann, Model Power, Rivarossi, Atlas, etc. The one exception was a Lionel GP-9 which has a high efficiency 5 Pole GE motor, all gear drive, and all wheels are driven and pick up power.(Not all of my locomotives are so well equipped.). The 50 year old model Geep, in normal daily service, ran through the water like it wasn't there, while 3/4 of my fleet stalled and made bubbles from the wheels and funny noises from the locomotive. I also have to give kudos to my treasured Atlas SD-24,(Original.), as I thought it was stalling, it was actually still moving, just slowly, and made it across the lake also. P.S. I think you should make either the infamous 0-2-0 (0-1-0 for you.) steam switcher locomotive, or the mighty 2-4+6+8-0 steam road locomotive.(1-2+3+4-0) or (1-Bo+Co+Do-0). This might be the contender you need to challenge Speedy Pete. P.S. My most powerful model, no traction tires, (Or chains!), has 6 ounces of pull.(Newtons please, probably a lot like your mid level diesel locomotives you tested.). I also run my trains outside, which gives them some nice, effective, realistic weathering. Keep up on the excellent train videos and "Goot jop, mi poy." ♡ T.E.N.
Thanks very much for the comment - Tyco have done that have they?! I have to see that! Thanks for this anyway - that all sounds good, well worth looking into that a bit more!! :D
Thanks for watching - Sam :)
Before watching, how many bottles of liquid gravity did you use?
haha none! The loco is no heavier than other models of it's size! :D
Thanks for watching - Sam :)
@@SamsTrains I was kinda ment to be a joke hahahaha
I copied him, and I used them gravity blocks that you rub on all the surfaces.!
And... I used 3.🤪
The strongest commercialised locomotives in HO might be the HOm ( HO for 1:87 and m for 1 meter gauge ) rack locomotives ( if you use the rack system ). I have a section of rack railway on my layout and it’s very impressive to see a long rack of coach going uphill with only one locomotive on a slope that normal locomotives in HO wouldn’t be able to manage
Thanks very much for this - I'll be sure to look that up! I wonder how much force they can withstand before the gears slip or break??
Thanks for watching - Sam :)
Sam'sTrains You have to add some more weight to the original model to pull heavy trains ( look at the FO HGe 4/4 37 on my channel to see one working hard going uphill) ;-)
you need to make these experements into a series
haha they sort of are really - I will keep doing them once in a while!
Thanks for watching - Sam :)
i love how speedy pete clings to the rails like Spider-Man on a 45 degree slope, reminds me of the Mountain engines during my time in Snowdon
haha yeah me too!! xD
If it can win a tug a war vs a tractor or a real train, then thats what you call HORSE POWER
(Im American so I don't know if thats what they say in the UK)
Also can I just say 13:00 is a bit insane
haha absolutely!! ;D
Yes, I was amazed by the angle it managed, lol! ;D
Thanks for watching - Sam :)
Actually, it's not HP it's torque. You can use a clock motor to pull a tractor trailer (real size) if you have low enough gearing. But it will take forever to move a foot. That's why Speedy Pete is so slow. High motor RPM to low output shaft ratio increases torque but reduces speed. Same is going on in your automotive transmission. First gear the motor spins a lot but the wheels don't spin fast. Lots of acceleration and pulling power but low speed. Second gear comes in at a lower gear ratio. You get more speed less torque. Third gear (or 1 to 1) is your highway gear (talking three speed transmissions) where the engine is turning the driveshaft at a 1 to 1 ratio. The only gear reduction after that point is the rear end ring and pinion gears. Typically 3.75 to 1 and 4.1 to 1.
For a second I thought you were gonna do an upgraded version of Gordon's hill but its just a steep climb for your experiment for how strong Speedy Pete is pulling Bullman around. I loved the name Speedy Pete BTW Lol. XD
haha yeah - but I needed something much steeper! Glad you liked that name, lol! ;D
Thanks for watching - Sam :)
So the title says: I built the world strongest model train!
Sam: “So this actually isn’t a model
Me: I have been ripped off
Hahahahahha
haha!! It's all a bit tongue in cheek... as you can tell! ;D
This was an interesting experiment. Speedy Pete looks like a backwards Droid tank from Star Wars.
haha thanks Ben! You're not the first person to say that actually, lol! ;D
Thanks for watching - Sam :)
A idea for a train build, make a fully solar powered train. Might need a cheap DMU of some sort possibly the budget Hitachi high speed train hornby made which was in the blue rapier set.
Hey Ben! I've already made that video... it's coming soon! ;D
Thanks for watching - Sam :)
Part of the problem is it needs to take up the slack in the chain with a tensioner (like in the timing chains in an internal combustion engine) and a chain guide. The second problem is the little pins aren’t wide enough, and there’s not enough of them. Finally, ditch the chain and 3D print a sprocket for the motor whose teeth will fit in the gaps between the sleepers (ties.) You’ll have to find a machinist’s handbook to get the equations for making a sprocket/gear, but this will be a much better solution than a train that doubles as a chainsaw. 😂 Just make sure to make the width of the sprocket teeth just slightly narrower than the gap between the rails by - say - 1 millimeter or so on each side. Now you’ll have a right-and-proper cog railway… once you fit some bogies with power pickup!
You’ve made one of those Swiss leaning cow train that go up the alps. That’s great
haha awesome! I'll have to take it to Switzerland and try it ;)
Thanks for watching - Sam :)
Whoa that’s SUPER strong!! Perhaps give the engine a body and make a mountain railway!
haha thanks mate! Yeah that would be epic actually - good idea!! :D
Thanks for watching - Sam :)
Hi Sam, that is a very clever thought aswell as the concept itself. 👍
Thanks a lot mate - really glad you liked the idea!! :D
Thanks for watching - Sam :)
This reminds me of when my dad used to go spotting at Nottingham in the 80s. He would see a class 56 with about 40 HAAs it would set off, the front of the train would be doing around 2mph and the back would still be stationary! It let off such a bang when they all finally started moving.
Great video Sam!
haha that's crazy - must have been quite impressive to see something as mighty as that!! :O
Thanks for watching - Sam :)
"Scared something will poke me in the eye" THEN WEAR SAFETY GLASSES 😭
haha! ;D
nice engine i bet if you put wheels on it you could classify it as a mountain engine like Culdee
haha yeah that's true - I do want to modify this even further! ;D
Thanks for watching - Sam :)
If you were to ever reapproach this experiment, I think something worth trying to solve the issue of how finicky the pickups are for power would be to put the pickups on the inside of the track (so between the rails), another option would be to use a set of wheels with pickups from a preexisting model and attach them to Pete, but that also creates a problem of how would the chain work if its being obstructed by wheel.
Nevertheless, a very interesting experiment!
Yeah this is very true - though it works much better without the insane load - it only starts to cut out with all the coaches and an incline! I had thought about it though - I may just wire a wagon onto the back of it, and let that do some picking up too!
Thanks for watching - Sam :)
Love your wacky hot glued together experiments, just imagine how well they'd perform if you spent more time on their construction :)
Very entertaining as usual Sam - great work!
haha thanks Gerry - I must say I enjoy the bodge projects!
Appreciate it mate,
Sam :)
6 newtons is around 0,6 kg of weight you could pull vertically (including the loco weight) and you could measure how much drag your couches procuce by pulling on them with that newton force scale by hand untill the last one moves
i am interested in how much force it actually takes to pull all of those on video
Yes you could indeed - I didn't think to try that actually, but it would be interesting indeed! The Vi-trains 37 could move them too - so we know it's less than 3N, or whatever it was!
Thanks for watching - Sam :)
9F m: pffftttt I can pull that cow up that ramp. Physics: Literally pulls it down
haha!! xD
This is the best vid😁!
SAM YOU LEGEND
But on a more serious note, who would win in a fight..
Thomas the tank engine or 1401 from Titfield Thunderbolt?
Why not the Thunderbolt herself?
@@badgerlordpatrick6493 She's as good as she ever was, I'll stake my living on it!
Ooh I'm not too sure... I reckon Thomas would have it, he has a bit more grunt! ;D
Thanks for watching - Sam :)
I know this is an old video, but do UP Big Boy in Ho Scale. You can pre-order one from Hornby/UK because Hornby/US kind of sucks. But it is a company from the Uk
When Pete fell, you sounded like a sheep! BAAAAAAAAAAAAAA
haha!! It made me jump, lol! I guess I turn into a sheep when frightened?!
Thanks for watching - Sam :)
What duration time??
This is definitely a fascinating video, Sam!
I'd wager a few quid that my Broadway Limited Imports HO Scale Big Boy would be a great contender for a pulling contest.
For some quick context, the engine has four traction tires, and weighs in at a little over 2 pounds without his tender!
Given all the bells and whistles he has (die-cast parts, smoke, lights, DCC, Sound), I'm surprised that I haven't tried to see his limits (probably because he's just a giant locomotive that barely fits on my workbench and I don't even have space for anything else when he's on one track).
The other part to it is realism when it comes to strength. I am one of the modellers that would rather see a relatively realistic rake of rolling stock (depending on the engine) behind the bunker and/or tender while the engine is at speed or marshalling about the yard.
A great video nonetheless!
Thanks a lot Hank - it would be great to try a big boy against this!! Ooh if it has tyres, then Pete might be in trouble! ;D
Thanks for watching - Sam :)
Someone should make a cog railway steam engine.
I know! That would be awesome! :D
Cheers,
Sam :)
Ferrotrains makes them in multiple scales
LGB used to make one in G-Scale
Speedy Pete is like a cross between the Montreal subway and a cog railway!
haha!! Except a farcically crude version! ;D
Thanks for watching - Sam :)
Speedy Pete needed more weight on the nose when climbing an incline
Yeah he did tip back, but it was fairly well balanced with those weights, it's just the chain made it very top-heavy!
Thanks for watching - Sam :)
Did Pete have any wheels at all? i didnt see any, maybe mounting the setup on a small chassis but using the same method of propulsion would aid it's pulling/ climbing power. Its a good idea though using a kind of Rack rail similar to mountain railways, i think with a little tweaking Pete could make that 45 angle.Maybe you could make a smaller version and mount it inside the body of a model, so it would look like a normal loco (ish) but with far increased pulling power. Maybe you could do a short video on Pete and how to make one?
haha nope - no wheels at all! Yeah it probably would have less friction if it were on wheels - but with all that power, I thought the friction caused by no wheels would be negligible!
Thanks for watching - Sam :)
Haha nice loco Sam you might consider producing them commercially, build up a franchise whahahah! ;-) Cheers, Joachim
haha! Yeah I'm sure everyone would love to own one of these, lol! ;D
Thanks for watching - Sam :)
ALWAYS Worth a Revisit/Re View ! TANKS ! The MOTORS STALL TORQUE Rating IS THE NUMBER, ASSUMING GREAT TRACTION !
Great video sam! I think you should try to get a loco to run upside down as in flip the track and loco over :D
haha that'd be awesome - I'd love to try that!! :D
Thanks for watching - Sam :)
I'm surprised you haven't use the newton metres on the coaches to see how much you can pull before it move.
Yeah that would have been good - in reality, they didn't need much at all - less than 3 newtons would do it!
Thanks for watching - Sam :)
You know, you should try and add to your layout some sort of hill. Something a bit close to Gordon's hill!!
Yeah that would have been brilliant - I may try one on future layouts! :D
Thanks for watching - Sam :)
sam, you are an absolute mad lad!!! something could have gone wrong! train could have exploded but thats absolutley crazy!!! amazing homemade "locomotive"!!!
haha thanks very much mate - you know me, living dangerously ;)
Thanks for watching - Sam :)
You have done a chain train, now how about a upside down train. You will need a length of steel track mounted upside down, a loco and coaches with steel wheels with strong magnets between the wheels in the fashion of triangs magnadesion, has this been tried before? If it hasn't I'll be looking forward to your video.
haha yes that would be the real challenge - I'd love to try that! Super-magnadesion would probably be a good way to go, you're right! :D
Thanks for watching - Sam :)

haha! Thanks for stopping in I guess ;D
So this time, you built an OO gauge experimental quasi-funicular loco.
Might be interesting to see what happens if you build an *actual* funicular setup, with a suitably long length of bicycle chain. That's a setup that could haul Bullman AND a house brick on wheels I reckon ... :D
IMPRESSIVE Fabrication with Speedy Pete ! ... Sam youz the BUILDIN' Master !
Speedy Pete vs Big Boy, that would be something
Oh yeah!! That would be cool - I still reckon Pete would win though ;)
Thanks for watching - Sam :)
Sam many thanks for the ideas Spedy Peter is divine and with a few minor changes and tunings you get him to climb a wall, continue to develop your imagination and build some more prototypes a hug
haha thanks Gabriel - glad you found him divine, lol! I like the idea of developing him to climb 90 degrees, that'd be awesome! :D
Thanks for watching - Sam :)
the fact this train can somewhat manage a 45-degree angle is pretty awesome. as mechanical speaking 46 degrees is the steepest natural stable angle you can get in nature (I am aware you can do 50 and up but those hills start getting landslide issues which also aren't used in construction 45 is when it comes to embankments)
Thanks very much John - that's very cool!
Thanks for watching, Sam :)

Sam'sTrains no problem mate I subbed to you
"We'll get 1 or 2 coaches."
Procceeds to fill his entire layout with 56 coaches
Haha that water experiment reminds me of the work the late David Mitton did for the Thomas series, Percy's Promise was just that on Gauge 1/G scale and brown food dye to make the water look muddy. Granted they could of been using trollys that were from Mitton's Tugs but I have no clue.
There are trains build for climbing steep hills, even under steam power, you find them in places like Switzerland, Austria etc.
The Germans call them "zahnradbahn", which means something like cogwheel trains.
Here are working models made of this system, available in HO witch has the same track width as OO.
They can pull up even steeper angels, but it's a fun trail…
coming to a exhibition near you, "Sam's Mountain Railway"
haha, maybe one day! ;D
Thanks for watching, Sam :)
I have been looking for a vlog I saw many years ago. I forget what club was involved but they were trying to set a record length train, I think it was HO scale. They had problems with one curve because of derailing. Then they added a DPU in the middle and solved the derailment but I don't remember if that nullified their chance at the record
Blimey that sounds awesome - I wonder how long the train was in the end?!
Thanks for watching - Sam :)
Was it the Airfix 31 or the Mainline 56 set a record years back , traction tyres though. Also track on carpet , disclaimer about furring up locos , as a student I used to fix so many friends trains that were furred up. Surprised over the Heljan comment. Yes the Clayton's were a disaster but with over 150 Heljan locos I have found then robust and reliable , unlike Vitrains!
I have videos of the legend that is an Airfix 31 pulling and incredible length of wagons on my channel. Also the Airfix Royal scots (6 wheel traction tyres tender drive) have a huge haulage capacity. I have also done tests with these
Thanks Paul - yes the Airfix 31s and Mainline 56s are pretty strong things! No issues whatsoever running on carpet, as long as proper cleaning and maintenance takes place - my 400 odd engines are all in perfect working order!
I must have been very unlucky with my Heljan engines then - I find almost all of them to be of dreadfully poor quality and design - most being pretty unserviceable too!
Thanks for watching - Sam :)
@@SamsTrains In preparation for an exhibition were my stock will run the club layout I recently had to review my stock. It now appears my total collection , OO and some HO is just over 1500 locos. 90% are super detail DCC stock and by far the worst are Hornby. I haven't had expanding chassis in either Hornby , Bachmann or Heljan but with Hornby I have had broken cardigan shafts , broken wiring , mis fitting contact strips and my big bugbear on Hornby 60s the swinging close coupling that needs to be so well lubricated so it doesn't through even heavy freight stock off when reversing into a siding. Make you appreciate the days when once you had detailed a Lime diesel and added extra pick ups it would easily run for a year without needing attention.
Yet another unique and amazing science experiment. The way you coupled all the coaches around the entire track reminds me of that Adventure Time episode with that dungeon train going in an infinite loop with every coach coupled around the entire track.
Thanks so much Thomas - and glad you liked that, haha! ;D
Thanks for watching - Sam :)
Sam'sTrains You’re welcome. You should try doing this again, but with one engine and one coach, or wagon coupled in between one another.
Kind of reminds me off the cog and rack style locos, but since it doesn’t use the rails for traction and uses its “chain/track” would it be considered a more of a tank ?
Yeah definitely! It was sort of inspired by those! :D
I guess it is more of a tank... a big useless tank, lol!
Thanks for watching - Sam :)

@@SamsTrains Yes plz Sam if it's ok with you i know your Very Busy but it's what the fans want it's Are job to make them happy Right?
Interesting experiment. Here is your stopping problem cause: you are using a metal chain in between the two power rails. Once it gets a little crooked it touches both rails and makes a short, stopping the power from the rails. Also your power pick up is super poor and cooper,brass track tarnishes very easily making poor contact. Use 4 unique plastic rollers that will roll on the inside edge of the rails and keep the chain drive centered and away from the track. Use 4 or more power pickups with some light spring action and you should be able to pull all of those cars around your track as long as the center is clear, no switches, no re-railers. Other options; use a plastic chain, make sure your cleats poke through between each of the ties (sleepers) smoothly like a gear would fit, just a matter of picking the right spacing to put a cleat, or better yet put the cleat (hard wire) on the outer link plate instead of the center pin, that will make spacing matching easier.
Thanks a lot for the thoughts - definitely no shorts going on though, since the controller would display as such, you're probably right about the poor pickups though!
Thanks for watching - Sam :)
There is a cog railway system from Fleischmann with a couple of loco models, I used to have that when I started out on the hobby.
I remember that it could do really stupid angles as well, but used a 1:2 gradient, which is 22,5° or a 50% gradient.
A cog engine is always suposed to push the coaches up the hill for safety reasons, but that didn't really work in model as my curves were too tight and buffers catched.
So I had my cog loco pulling the train and sometimes it did uncouple, leaving the train running down the incline, derailing and smacking against the rock face just off the tunnel portal.
So I wrecked several quite expensive Fleischman coaches, and on the next layout there never has been a cog railway.
I have some continental Roco Co-Co locomotives which have good pulling power, equal to the Vitrains, but my strongest loco I once built was a Garratt steam loco in Ho which could pull over 150 wagons, which was full circle on a large club layout. it finaly pulled one of the blades from a point when the train derailed and got stuck behind the platform end
I've been hearing about that Tom - I wonder how much force they can muster? Blimey, sorry to hear it wrecked a lot of coaches though, haha!
Thanks for all the info,
Cheers,
Sam :)
I can see it coming to Sam, a special purpose built roller coaster with perhaps a Deltic with Pullman coach themed OO loop a looping thrill ride? Years ago I was in charge of the train set in a video store where we sold Video Camera's pointing at a layout and I thought wouldn't it be fun? My boss took the train layout before I wrecked it and gave it to a local children's home and bought some giant Disney animations instead and he did not speak to me for a few hours! Well, I was the one who had to clean the track every morning and was bored silly. Great videos and wondering what's next for Sam's Trains?
That'd be fantastic Ian - I do hope to create a loop for model trains one day, haha!

I've only just caught up with this video. I enjoyed it a lot. You'll be too young to remember this but Hornby Dublo used to stress how powerful their Co-Bo diesel was in magazine advertising. They set up a test track with a trolley on it carrying a young lady. The combined weight was, if I recall correctly,11 stones. Three Co-Bo's managed to pull it.
Blimey did they really?! I'm amazed that it could actually do that - very impressive indeed!

I love the crazy stuff you do on your channel
Place the chain in the middle of the tracks and let the motor drive the sprocket that is in contact with the chain and thus drive the motor. This type of drive is counterintuitively often used in the mountains and such a railroad is called a rack railroad
Please keep making theese types of videos they are so fun!
