This sounds like an idea that when first suggested, everyone laughed at until one guy at the meeting table went, "ok guys, but seriously..."
"We gotta speed up the passenger lines to outpace our competitors. I'm open to suggestions."
"We could engineer better-accelerating trains."
"Make it easier for them to accelerate by dropping the last couple coaches at the station and having another train move them off the line, while the main one continues onwards."
"Why bother stopping at all to disconnect the coaches? lol"
[Everyone lols]
That guy known for being no-nonsense:
Man: "Oh crap! An engine is coming, let me step off the rails. Phew, that was a close one.. Atleast now I'm safe."
Slip Coaches: "Think Again."
That really has to suck for the man tho. Comically tragic.
Where was the clip
Train: Hi
Man: Ok bye
Coach: *Hi*
Man: Oh crap
Slip Coaches: "I'm going to ruin this man's whole career."
Depending on how visible the track was when he stepped off (I can imagine situations where the following coaches would've been hard/impossible to see from the spot stepped to, you'd have to hear them and realise) that was some horribly bad luck.
The visual depiction of how Slip Coaches are used was perfect
ikr it was glorious
I really like his humor.
Agreed.
Using James's theme in a video about coaches is a deep cut indeed.
And if he wants to keep mucking about, we'll put him back on mixed freight! :p
"The trucks giggled". :p
Hide your bootlaces!
What makes it better is basically the episode of thr slip coaches was James proposing the idea even though it was ducks idea
oh yeah i rememeber that when he stopped at station after he released the last couch and bumped into him
I always assumed slip coaches were an "old-timey thing" that was abolished as trains became faster and safety features like pneumatic brakes were introduced at the end of the 19th century, but in fact this practice could have been filmed in colour.
I like that James' theme is in the background.
It works and it's utter quality
Instantly recognisable! Lol
Thomas themes in the background of videos can’t be beat
And it fits with a episode based on these coaches were James pulled them
@@slayerphoenixx6947 my thoughts exactly.
"NOOOO YOU JUST CAN'T LEAVE THE COACHES IN THE LINE THAT'S DANGEROOOOUS"

Its a meme

What a beautiful artist show of how slip coaches work. You are quite an artist
When I worked on a train years ago, we were climbing a 4% grade and it was booming tourism season, with a bunch of unused surplus cars being used due to the unusually high PAX capacity. Our SD70Mac engine was unable to get up all the way, so we had to disconnect half the train, disconnect the locomotive and push the rest of the train up the hills. The location was the old “loop” on the Alaska Railroad, so the PAX weren’t complaining about the glacier views all around while stopped.
The only surviving Slip Coach is on Cornwall,Its called "Railholiday Hotel"
The Danish ICE train was intended to be (sort of) a modern take on this. Not dropping coaches (all units powered) but to be able to link up and separate under way to reduce line congestion. Train A would start from one city, train B from another, when they reached the same track they'd link up and now you only need space for one train instead of two.
Turned out not to be very useful in practice, but it was a neat idea.
You mean whilst running? That would be pretty neat.
I think you mean the danish IC3 (class M3) diesel MU:s built by ABB Scandia. Before the Great Belt bridge/tunnel was built the ability to "split in motion" was in fact used when running onto the train ferries in Nyborg and Korsör (sorry can´t find the danish Ö on my keyboard...). I´m not sure if it was used for rejoining the trains after leaving the ferry - but maybe...
@@tompao7832 Yeah, IC3. Sorry, my brain always want to turn that "3" into an "E"...
Anyway, interesting. I've always heard that it was never used in practice. Thought arguably using it to essentially simplify switching might not have "counted".
@@henrikgiese6316 I made the sam kind of mistake in my comment - the class is acually "MF", not "M3"...
Wow, impressive, taking into account, that standard UIC scharfenberg couplers can take several tries to properly connect and even then both units need several restarts to get can network configuration correctly but only from right end of right unit and on even day. :P
I remember being in a slip coach travelling from Cornwall to Swindon.
Several Airmen as well as my family were going to RAF Lyneham - we then went on to RAF Changi
I like where you use James’ themed for this video, and as well it’s reminding me the episode Duck & the slip coaches in Thomas and friends.
I actually learned something new about slip coaches today with this video. To learn that slip coaches were not exclusive to the UK and were used in the United States is almost hard to believe!!!
That poor guy that got hit by the slipped coaches. What a humorous way to die lol
Agreed, if i'm gona go out, it better be silent but deadly
@@Foxttellio I don't think he died silently, he probably heard a clank, and the rumble of steel on steel
@@royr1016 I wouldn't be surprised
@@royr1016 Holding the land line phone with both hands and dictating the text for a telegram which should be sent to his cousin in argentina.
I guess he did not trusted his ears since the train just passed.
But everyone working with rails know that rule Nr. 1 is to always look in both directions before crossing.
I thought the slip coaches had a cool trait, although I didn’t even think about the passengers wanting to either go to the loo or wanting something from the snack trolley. It just comes to show that we should be more considerate of the passenger’s needs other than their stops.
It's not so much about the passengers stop needs. Trains back in the day took a long time to stop and a long time to get up to speed again. The time lost by stopping could be considerable, not like modern trains which generally get up to speed slowly compared to most other forms of transport, but still in good time. The minor inconvenience would probably be worth having a more frequent service, and if it wasn't for you then you could just use a branch line train instead, noone's forcing you to use a slip service.
The passengers would be disconnected when they were already pretty close to the station anyway, so lack of refreshments or loo breaks aren't such a big deal
I’m running off of memory so I don’t know how accurate this is, Another thing that was related to this and common on backwoods US railways was some of the wooden truss bridges weren’t necessarily super stable and couldn’t support a train AND its rake of coaches all at once. So in some cases, the locomotive would get behind the coaches and push them across the bridge and let their weight and momentum carry them across. 1 Coach at a time typically wasn’t too heavy for the bridge, but sometimes a station on the other side of the bridge was called, so another locomotive could pick up the coaches on the other side because locomotives are significantly more heavy than coaches. This was a long time ago if I remember correctly, around the time the transcontinental railway was being constructed. The locomotives used at that time were mostly 4-4-0 “American” types.
my man really put James' S1 Theme, and I love it
I love this channel. Please never stop uploading!
Even after the sun has exploded and has taken the Earth with it in the process, he will still be uploading
The main question is: what if the train runs out of coaches?
Good question
Goods wagons
@@blehtbh ah yes, economicality
The tender is always an option
use yourself
Things rolling stock were useful for
1: Coaches for carrying passengers
2: Trucks for storing staff like coal or China clay
3: Break vans for stopping for emergencies
4: Wagons for taking animals and boxes
5: Tankers for storing liquid resources
6:Flatbeds for carrying anything heavy things
7:Mails vans for delivering mail
8: Breakdown cranes for emergencies
and 9: Breakdown coaches for emergencies use.
it's James theme, which is ironic because James stole the suggestion and idea from duck.
Here in Canada we have a few trains called "J Trains" where we couple two seperate trains together. These trains are used when two trains are departing from the same origin but have different destinations. Whenever the train gets to the junction the train is stopped and the second train is detached from the rear. These are primarily used for the Toronto-Ottawa, Toronto-Montreal service where the Ottawa train gets uncoupled to head north while the front continues east to Montreal.
Detaching trains still exist in around the world, one such train is the S-bahn here in Germany. Its technically two trains attached to each other and passengers either board the front or rear. During the trip the trains seperate and go their separate ways.
The difference is though that today it is done with the train stopped, but back then they did it with the train moving.
The route I used to use top get to work (east midlands railway) use to split the train at Kettering. One half would continue on to Leicester, but the other half would head to a branch going to Corby. Its now been replaced with a dedicated electric service.
But that is slightly different and done for different reasons to this. wild to think would let coaches roll!
Thhat high tech software at 0:48. This channel is going places.
I never knew that the U.S. had slip coaches as well. The closest thing I remember seeing is old footage of the Budd RDC railcar splitting up its formation at a station going in opposite directions. Great to see some more attention brought on the slips.
Slip coaches disconnects the people closest to the corridor's"THE TRAIN DISCONNECTED,AHHHHHH"
i know it's a joke but thats why they didn't have corridors between slip coaches and the rest of the train
The slip coach guard would sometimes be a bit too keen on the brakes leaving the coach stopped on the line, so the station pilot would be ready for the rescue.
Great little story! Really enjoying the quirky stuff you cover - excellent.
I love these videos! Subbed!
*Hears James' theme in the background.*
Ah, I see you are a man of culture as well.
Love that you included a picture of the prospector in this video.
The animation describing entire process... is an art, good job mate, good job.
I've heard the term slip coach, but never fully understood their purpose or how they truly worked and for the technology at the time it was an ingenious solution.
So that's what a slip coach is! Dang you answered a question I'd had for a while!
I have seen freight trains do similar moves when doing switching. A car will roll down a track with a facing switch
I was thinking the coaches would release and coast to the the next stop and that took great calculation to arrive without slowing down to fast or not fast enough. Also depending on the weight that was on those coaches affected speed.
The idea of the slip coaches is pretty cool. Disconnecting the coach from the rest of the train at a station along the line saves time for everybody, especially the railway running the passenger trains.
Top tier demonstration
I am so happy when James's Theme popped in this video!
1:39
Perhaps Thomas' Special Coach was a Slip Coach? That would make for an interesting story.
Love the animation!!! Fascinating content as always. Thanks
Will you ever talk about broad gauge
Love the James theme playing during the video but honestly I feel like duck's theme would had been better since he eventually got slip coaches
A unique invention at the time! Another great video - always tons of information packed into a short space of time. 20k views in about 24 hours too. Some going!
Nobody:
Duck: Hello Slippies!
I think there would be use for slip coaches today. The high speed rail needs quite a lot of space, to get to full speed. In Germany for example big citys are just to close to each other to use really high speeds. So I can see the use of slip coaches for shortening the travel times of the Cities, that are far apart.
I’d imagine another reason for the discontinuation of this practice is air brakes, if the air line is disconnected the train would immediately stop with no control
well no, the air brakes are bled off or the air line is bottled. Cabooses for example used to be dropped all the time similar to slip coaches when the caboose needed to go the service track and the train needed to be yarded on a different track. There is a rod to bleed off the brakes internally inside the caboose. Another way is to bottle the air and then dumping the air when you want the cars to stop. The old heads where I work used to spot an industry like that, tripping the fred to dump the air when the cars were in the clear.
With modern EMU/DMU trains, and often longer trains in my experience in UK at least often being done by combining multiple fixed length sets, I guess the modern equivalent if they wanted to bring it back would be to split at those sets and have 2 functional trains.
On the other hand with how much it seems to be costing them for a few added carriages on busy routes...maybe they should bring the "dumb" carriages back
There’s a cutoff valve at every coupler so the end of train won’t discharge the brake line into the air.
Me knowing why James' theme is playing, due to his history with slip coaches: Level 100 nerd
Actually I think this idea is more plausible for EMU trains in modern time. Sometimes several EMU trains are connected together to run service and each of them has seperate control system.
The shinkansen has that system using auto-coupling. From tokyo the 2 trainsets are coupled together. At a certain station where it branches, the whole train would stop there. Both train service that station. The front would depart first to continue the run, while the other would now start its branch service.
Any Duck fans here?
I love that you used Thomas music
Wow, I didn't notice the well-themed 'train-music'
Can you make video about Race against train at Talyllyn Railway?
Taking a train from Taiwan to France, while also travelling back in time.
They still do this in a way at Machynlleth or Dovey Junction on the Cambrian line where the train to Aberystwyth is the front two and the train to Pwllheli is the back two using 158 DMU's. It was a GWR line so was where some of the last slip trains were used.
I remember watching a video that explained the very basics of slip coaches. They didn't have all of the information though. This filled in the gaps. Also, I like that you used Thomas and Friends music.
Top quality graphical explinations!
I found out about Slip Coaches cos there was a T&F episode about it.
1:21 montparnasse made me laugh so hard xD
Try how Union Pacific did when they worked along with Alco for their FEF class. The FEF class was built mostly with single casted parts, the frame, wheels and axles are single casted. The FEF class was never built in traditional methods, which is why the FEF, Challenger, and Big Boy have fewer small parts than other locomotives. Later on, the Union Pacific's Living Legend 844 was fitted with Multiple Unit systems, meaning, the Steam crews in the steamer can also operate a Diesel locomotive in tandem.
MAKES SENSE......ENJOYED IT................merry xmas................
'Very happy I discovered your channel 👍
Slip coach is my favourite passenger wagon ever
It was nice to see The Prospector, a Western Australian train running 653km from Perth to Kalgoorlie. I often drive past it when it's stopped at the East Perth station.
Good to see a photo from my home state of Western Australia at 3:31.
“You know, days like these rimed me of the time I was on the Great Western Railway.”
When Dad used to take me to London years ago, we would be on the slip coach on the way back to Bicester.
Not sure I'm a fan of the very purposefully-armature demonstration, but the story itself is well told, so it gets a thumbs-up.
Thank you, I have heard of slip coaches but never knew what they where.
James theme in the background and the slip coaches story. This is a special video
Nowadays with individually powered coaches it would be even more interesting, i'd imagine. Why stop at only letting people out?
After letting people out, the coach could wait and take people in and then attach itself to the next train, allowing to board a train as well as leaving it.
Of course this would be very difficult to do, especially to do safely and require a lot more tracks and infrastructure.
Great vid ToT first learned of slip coaches from Thomas.
James' theme. Classic.
"Norwich In 90" could be more easily achieved by adopting hi-tech Slip Units behind those suburban-style Class 745 EMU's on that InterCity route at Colchester & Ipswich.
I did not know this ! I love learning cool odd stuff like this. Thanks. I'm gonna subscribe.
Maybe one of your future videos should about the history of automatic air or vacuum brakes
More or less the same technique has been used to cut off helper locomotives (bank engines) on the fly in North America as late as the early 2000s, with a piece of equipment called ‘Helper-Link’, which electronically controls the brake connections on the trailing locomotives, allowing the disconnection at speed without putting the whole train into emergency.
U know what they say, “A Train of Though video every Friday keeps the Depression away”
Also f I R s T lOl
The photo at 3:32 shows a "TrainsWA" train from Western Australia.
An episode on Big Bertha would be Really noice to see (not sure but doesnt b,b have a really cool history)
Very good video, and is funny to think being in that situation for the very first time
Given the long Penzance to Paddington run, and the number of stations from Taunton onward I’m not surprised it was GWR running them the longest
I think the last slip was actually at Bicester on the Paddington to Birmingham line.
You should do a video about the USATC S160s
Amazing review! Keep up the good work.
Can you make a video about the camping coaches?🚂🚃🚃
Review?
@@francisluglio6611 Sorry, I'm used to watch Tv show reviews, so I mixed the words up. I just meant video.
Imagine going for food to the other coach and the moment you try to come back to your coach it has dissapeared
Love how station c is just The Montparnasse Derailment
The second I read the title and saw the thumbnail I instantly thought of slip coaches
Funny how the image for Station C was that trainwreck that inspired Hugo.
I saw the pictures that you are explaining, picture A seems like Taiwan Railway, did I say wrong?
One thing that always puzzled me about slip coaches is... what if you stopped early? Either you apply too much brake, or there's like a yak on the rails and you have to come up short, you have no power, does the Guard have to get out and push?
Stations that had slip coaches would have small shunting engines to move the coach around after it had stopped, or there would be a branch line train waiting to pick up the slip coach and take it onwards. Either of these could be used to rescue a slip coach that stopped short.
are you ever gonna cover Beyer Garratt Locomotives?
1:35 James’ theme play through out this, uhm, whatever is happening here, is just funny to me.
Do you know anything about a train that went between Edina, MO and Monmouth, IL? Thanks
I have heard of corridor slip coaches, but they don’t seem to have been common. One downside is that the guard would have to pay special attention to the passenger list to avoid having the whole train make an unscheduled stop if someone was late returning from the restaurant car!
I don't think you were allowed out of the slip section... or if you were, you just get left.
i like your illustrations
I’ve heard this before. Reupload?
Just last week I travelled in an ICE from Berlin to Düsseldorf. The train split in two before the Ruhr valley. The front half went through there (stopping several times along the way) before finally pulling into Düsseldorf. The other half skipped the Ruhr and went straight to Düsseldorf (afterwards moving on to Cologne and Bonn if I recall correctly). Not quite the same thing, of course, but perhaps interesting too.
Split at a station? In UK a lot of the trains I took to travel down to Brighton (London Victoria -> Hove route specifically) area do that, I assume to reduce congestion out of London Victoria as can have one long train with a lot of coaches but our safety requirements would require a significant gap between two small services ran separately.
These coaches are the same coaches that were saved from scrap in the book "Enterprising engines"
