Tri-ang Class 77 "Electra": Repair Request
HTML-код
- Опубликовано: 22 апр 2021
- I was sent this Tri-ang R351 Class 77 "Electra" from one of my subscribers.
I've never seen one of these before so it was fun getting it running again. I couldn't get it running as quiet and smooth as I'd like but I think with some running in it'll be fine. I had to fit new drive wheels and axles.
Very special thanks to Steve aka "Newburgh Model Railway Specialist" who helped me out with new wheels for this one. Please check him out at / newburghmodelrailwaysp...

Greetings Bill, enjoy your channel🎉. Regards Elizabeth
60 years old and still a very impressive model. Just ooozes charm and robustness.
later because its in the post 65 br livery.jpj
Never fails to put smile on my face, seeing each problem overcome. Great tenacity Bill 👍🏻👍🏻
What a great job you done there on a lovely old loco ever thought of being a surgeon LOL nice one Bill
I have a green Electra in very good condition. The sliding switch on the roof (centre rectangular block of the three) allows you to set it to pick up from the track or from the catenary. This video has helped me to look at servicing my own model.
Hi OOBill,
Interesting tube cast regarding the EM2. The very rare ones the light BR blue of which I had in 70's and which I wish I still owned! On the roof theirs a slider switch that switches power from the bogies to the psntographs. They never were very fast runners for some reason, 2 friends had them too. 27000 Electras now preserved at the Midland Railway Centre in Derbyshire where I live. It was brought back from the Netherlands who BR sold them too. I too enjoy buying non runners from ebay....... so watch out!
Kind regards
Pete
Sounds like a Stuka ! Great looking loco Bill.
These EM2s where sold to the Netherlands in the seventies where they provided good service for another 10 years or more. At least 2 survive. One in the Netherlands and one was returned to the UK.
think the one in the UK is in the NRM in York, not sure though
@@Xantec 7 were constructed. 3 remain. Not in York. See Wikipedia.
You have worked your magic again. Fantastic as always. Understand the care one needs for something that old and special. Superb. A joy to see and hear at the end. 😎
Great old model,glad to see it going again.Well done Bill.
Nice service bill, nice looking model, one benefit of doing these repairs you do get to see other things some like you say you've never seen before! Must be nice to see some guest engines on the layout from time to time. Good man you've got bucket loads of knowledge and care you put into these problems. Looking forward to seeing what next. Take care Eddy xx
Good Morning Bill, The EM2 class 77 Co-Co was used between Manchester and Sheffield via Peniston as were the EM1 class 76 Bo-Bo, they were based at Reddish Depot at Manchester running on 1500 volt DC on freight there were 7 class 77's built in 1954 at Gorton and there were 58 class 76's built at Doncaster in 1950 26000 Tommy was built 1941 in Doncaster.
Nice to see such a classic model restored to working order! Excellent work!
You have just helped me fix the top switch that switches between overhead power and track power, when you got the motor bogie out I realised there was a part on the one you had that was connected in a different place compared to mine, thanks for the help.
I have one also and was trying to see where he placed the end with the semi circle pick up?
Six of the real thing was built in 1954 to haul passengers across the Manchester to Sheffield 1500V DC overhead system best known as the Woodhead line. All these class EM2s (would have been class 77 in the modern system) were named after classical Goddesses. There was a plan at one stage to build 21 more and to electrify the line at 1500V DC all the way down to London but this was shelved once the mainline electrification standard for overhead was changed to 25KV. Withdrawn in 1968 and sold to the Dutch railways were they were rebuilt and continued working up until 1985. The Triang model was highly prized and is a very good model for its time. A Heljan model has replaced it which cooled the prices of Triang ones considerably. The model could take power from either the track or via its pantograph, hence that rotating part on the top of the spider. The switch is the centre of the 3 longer oblongs on the roof, slides back. Still a lovely bit of kit and a reminder of what was Britain’s first electrified main line and it benefits from your attention.
After a very cautious approach it didn't take long before the hammer came out...Did the trick though. You transformed that into a lovely little runner.
I was given one of these for Christmas as child, it was a CKD so I had to build it. It was never a fast model (in real life they were restricted to slow speeds anyway), but if it can pull a decent load, then I think that is all that can be hoped for. I used to love seeing the sparks form the catenary when running at night. I've now got one of the Olivia's Trains versions (and a couple of class 76s too) fitted with sound and they are fantastic models.
The EM2 was developed from the EM1 which - amazingly! - was a Nigel Gresley design.
Really enjoyed this one - It was great to see this run round the track!
Great video you are so cheerful and love watching your repairs.
Thanks for this. I have a green version, bought back in the early 1960s when I was a teenager building my layout. One of my favourite locos at the time, although the catenary system was a bit of a fiddle. I still have the model, but I'd painted it blue way back then. I managed to buy another Electra a few months back, but as you have said, the good ones are approaching £180 or more. I remember it always being a noisy runner too!
I sold a boxed blue electra in 1995 for the princly sum of £80 which was the going rate so they've shot up in value a bit
Beautiful model ❤️
As other posters have said, these ran on the Pennine "Woodhead route". A pre-WW2 modernisation concept, it finally opened in 1954 and two years later government decided to adopt AC as a UK electrification standard, making the DC route a white elephant.
Almost a white elephant, the tyne and wear metro uses the same system and opened in 1980
Bill ran on the Manchester to Sheffield line now closed and used by electricity network through the former Woodhead tunnels. Usually ran double headed mainly coal, occasionally mixed traffic and passengers.
Think you have got mixed up there, the ones that double headed were the 76s or the EM1s as they were also known, the model in this video is a 77 which is an EM2 and I haven’t seen photos of these hauling freight or double heading with each other.
S3374 !!!!! After watching this I went downstairs and took a second look at mine which hasn’t been running. That part was missing and I guess when i was putting it back together I must gave misplaced it.
Now I will need to turn the place upside down to find it or I put it on a list to order 👍
It may not have been there. Despite being shown fitted on the service sheet I think these things did manage to work without them so long as the pantograph sliding connector is working. But if you fit this part it'll run regardless as normal from the track alone. You could probably make something to make that connection.
It dies run when I apply the battery
It does run when the battery is applied
It will if you apply the battery to the brushes. But current won't get to one of the brushes from the wheels because of that part not being there. It connects the pickup to the brush retaining clip. Once you have made that connection it should go from the track.
Triang EM2 I have a green version the switch for the overhead pantograph is the middle long moulded piece on top that slides.
Used on Woodhead route from Sheffield Victoria now defunct to Manchester and Wath coalyards to Manchester.
6m 33 secs, removing the magnet without a "keeper" causes demagnetisation, a major drop off in magnetic strength, you need to have a metal "keeper" around the poles of the magnet to preserve the strength of the magnet, see the Triang Service Sheet
I know. But I have a remagnetiser so ...
I'm not sure whether or not I like the look of these locomotives or not. Either way you've done it again Bill
Overhead electrical pickups are called pantographs.
A lovely model and no question. I have a 31 that runs slowly too, and i had to move the worms in. I've been thinking about how to replace the bearing as well as the bush. the gear wear always seems to correlate to broken bushes.
another impressive repair
best wishes
will
The bushes are ok on this one but I know what you mean. If the bushes are worn and the armature starts dancing then there will be friction on the gears. I think Tri-ang and Hornby didn't fine tune the position of the worms on these motors and they were often meshing too tightly out the box. My 37 made a horrendous noise when new back in 76. So a lot of the wear is just a bad gear mesh. That in turn causes vibration which increases wear on the bushes causing more wear on the gears and eventual failure. I think...
@@oobill the dock shunter design would have done well, the speed on the 31/37 seems to vary model to model. The plastic bearing on the axle isn't very good when not well lubricated. I think it would be too loose between the poles with a full length armature. they did a similar think to what i said on the TT 31
your servicing videos are a highlight to watch
stay safe
Will
Hi Bill, You are right about the price. Good boxed ones go for about £200.00. In real life this engine used to run on the Woodhead line pulling both passenger and coal trains. I used to live close to the line. You could also try early Triang class 31 engine wheels as a replacement for the worn gears.
I got one for £40 a couple of years ago runs brilliantly as well was a great bargain.
The speed limit for woodhead was 60 mph but one of the EM2's did 90 mph on a demo run for the dutch , must have impressed them because they bought the lot so it doesn't need to go that fast unless your selling it to the Dutch lol
Yes in Triang terms these are not that numerous. Introduced in 1961 in green it then went to electric blue and then BR Blue as this one is . Dating from 1968-1972 . Triang wanted another electric loco to increase popularity of their catenary system . Trix already produced the EM1 (class 76) so Triang did the EM2 (class 77) . Very well regarded at the time and to this day . Quite an accurate model . The motor bogie was developed for this and went onto go in the Class 31 and 37 . It was designed to operate either from track or catenary which meant you could operate two locos independently on the track at the same time . The switch is neatly concealed in a roof panel . If you ever come across a Triang AL1 (class 81) it had a similar system but was a Bo-Bo . Really quite a smart system considering this was 50 years ago. If you don’t already know it have a look at Oscar Paisleys RUclips site which has lots of great period models . He had covered the 77 quite recently . Sorry I’m a bit of a Triang bore as it’s my childhood!
Nothing wrong with being a Triang bore 😊. I was going to suggest Oscar Paisley too. His channel sparked my interest and now I am hooked!
@@PaulinesPastimes Thanks Pauline . I do tend to go on........
@@russellbenton2987 😊
These would have run on the now defunct woodhead line Manchester to Sheffield
Pantographs work with catenary systems, I think you shall find, that they were used with trams and trolleybuses, the first electric train in the world, was the Volks Electric Railway in Brighton, I assume the first catenary system for trains was probably in Switzerland.
If you have one of these and want to modify the wheels. You can take the original bogies off, store them away and fit modified ones with new wheels and pick ups from the Triang Hornby cl31 or cl37. There are many of those about,and it’s the same bogie mechanism with a different design of side frame.
I know. Trouble is those horrible great big rivets. I've seen some awful damage done by people trying this. I'm thinking more of just replacing the wheels and rigging up pickups and keeping the original bogie.
@@oobill yes you really need to drill out the Triang trailing bogie rivets. I did that on some old transcontinental coaches. As I want to run them on code 100 track. Replacing the bogies was easier than re-wheeling the old bogies. As you say the Cl77 is valuable. I bought job lots of old Triang stuff to practice on. I would never be brave enough to innovate on some of the expensive stuff! Love your channel as I am more in the bargain basement budget for rolling stock. Your skill and advice through your videos is invaluable.
These Class 77 models were designed by Triang to either operate from the track ( traditional 2 rail) or from the track and an overhead catenary wire via the pantograph. Somewhere on the model is a switch to facilitate this ( without getting Pat Hammonds book down And checking I can’t remember where it is. The power bogie has a marker on it to show how the locomotive is orientated on the track when collecting power from the overhead. Some of the noise is due to it having ribbed wheels and also the fact the flanges are a little on the large size for System 6 track so they are running on the sleepers.
@@vobbertbecking3598 That had happened to mine I have just been able to fix mine and get that switch working properly again.
The switch is on the roof in the middle and on the bogie there is the letter I on one side which means that that is the insulated side, I think it is that side that has to point to the side the power mast was connected to the track.
I had John Chambs123 provide me with a machined set of wheels. Made a difference
Pontograph goes up to contact the catenary. Kind regards Dave
Pantograph 😊
Wow that is such an improvement :) Can I send you mine, please?
Any ideas on how i could possibly send you my loco for you to look at for me please?
Sorry to say this but you may have made an error, as the electrical arrangement at the top of the bogie is different on the EM2 to the other models with similar bogies, the pick up strip should not be connected to the brass retaining nut atop of the bogie, the contacts inside the body contact the pick up strip, current is taken from the body contact or the pantograph depending on the position of the switch, current then flows through the sliding strip that retains the bogie then through the large brass nut. Whilst the loco will work fine when powered from the track, you could not now power this from the overhead and have another loco powered from the track on the same section of line as the additional link between the contact strip and the brass retaining nut will cause both controllers to electrically short together.
Correct!
I forgot to tell you was.first line was run by overhead cables just after the war 1947
At 17.46 how is it running with the top middle slide not in correct position, I note at 21.00 the top middle slide is now set correctly plus how is the motor alone/ not in the body running, I thought the motor had to be installed to actually run
Yes I do it on woodhead Manchester Piccadilly to Sheffield victory it run on DC 1500 v. Was two types a Coco and the bobo.bobo was this one Coco went to Holland back on 1960 s was bass at guide bridge in Ashton Manchester this was freight some time on passages to Sheffield old station top speed was 80 mph stop running in 1989 when the depo shut down I was the driver on this local
👍👍👍
Bill was it Newburgh Model Railways for the parts?
I shave a wooden toothpick Sharpe and use that to clean comutator slots
Another superb and instructive video, can I make one very small criticism please? I am deaf and rely on sub-titles to follow the action. Can you ask RUclips to display sub-titles on all your series of videos? I'm sure I'm not the only deaf old git that subscribe and look forward to seeing the next locomotive resurected from the dead or severely injured siding.
the model drew power from th ohl as well
I'm interested in buying a Lima or a mainline diesel from my local model railway shop any suggestions. Cheers .Lewis : )
Lima diesels are quite nice and will run great with a little work on the motor or can be converted to CD motors quite easily. I haven't worked on a Mainline diesel but haven't heard anything good about the motors and gears in them. Noisy, poor quality and few spares available. I would stay well clear of any Mainline locomotive. Steam or diesel.
@@oobill I have two mainline steam locomotive and my 4mt is more reliable than my Manor class as the Manor has got axle problems and I think she has split chassis problems but thanks for the advice I love your videos and I thoroughly enjoyed them and your locomotives so keep up the informative and inspiring and amazing and relaxing videos cheers. Lewis . P.S I would love to go to Scotland and visit the Bo'ness railway if I spelt the name right as I am English and I don't have any Scottish and I can't pronounce Scottish names very well and I don't have any Scottish in my DNA but instead I may have 0.1% Irish in my DNA
they ran on the manchester/sheffield line trans penine.jpj
The class 77 uses the same wheels as the triang class 31
ultrascale do replacement wheels sets
Of course it wont run you have no overhead wired lol
