I remember travelling on the 83ts as a child, I used to love them-opening the doors at every station, must have really upset everyone else! However, I don't know much about them, as far as I know they ran as DM-T-DM+DM-T-DM. How many compressors did they have, could they run as 3 car units or did they need to run as 6 cars? Why were they made into 6 car trains with two middle cabs when the 73ts (mostly) had UNDMs in the middle?
Cheers

I would assume it would have 2 compressors as that has been standard on a double ended unit for a long time.
A guess, but the all double end units would have been because the traffic predictions for the Underground when the trains were ordered were pretty poor - so hence the single doors (to save money on door motors) and double end units (so if half a train is needed for maintenance the other half could work the line whichever way round the other unit is.)

I would've thought that a unit with a cab at each end would have 2 compressors.

Well thats what I was thinking unless they were all special trailers! Off course the DM could have had compressors on instead?

The 83s had only one compressor on the trailer car. The first unit had to have a portable compressor mounted inside the saloon while it was being tested because of the rule that you must not run a train with only one compressor.
There wouldn't have been room for two compressors as they had three MAs under the trailer - one for each motor car and one for the fans.

See I knew you would know! So the 83ts had to run as a 6 car train. 3 MA is a lot, and from the sounds of it wasn't enough considering the trouble they had with lighting etc! Were there many differences between the batch 1s and batch 2s bar reliablity?

See I knew you would know! I didn't  I had to look it up! There were a number of detail differences and some of the early trains had to go back to Metro-Cammell to have the bodies altered as they were out of gauge. That made more differences. Reliability was poor - particularly the MARs, traction kit and bogies. |

Did the bogies have the same problems as the D stock bogies-weren't they similar? Its a shame the 1983 stock couldn't have been more like the 73ts. I believe the windows had to be flat because of essential corner pillars (or curved glass was too expensive!!).

I used to take them everyday they were great the good thing about the doors was you could stay warm in winter

Did they? I don't remember UNDM in the middle. They had cabs in the middle I thought!

just realised on the metropolitan DEV at finchley road a 1983 stock comes into platform 3 and it has two cabs in the middle

I think it was too the last stock (except DLR) to use the bobble strap hangers as opposed to the grab poles; the formers many still favour as apparantly they were easier to hold on to.

It's the last stock /built/ with grab hammers - the last stock to use them is still (just) in operation...

If there was only one compressor on the unit,how did it get its' feed if the wrong cab was on rail on a train in the shed?

I'm rather tall and thus happen to favour the poles! ;D A true story...the "M" stock exported to Hong Kong had the exact same bobble strap hangers until around 2000. When the trains were first introduced in 1980-ish, females were very reluctant to use it. Please use your imagination why, as going further would probably violate forum rules - but it's the truth! |

M trains don't have them now; replaced with semicircular red grippy things... EDIT:Same for K-stock. Like this  |

I can tell you that the MTR in Hong Kong has a reliability that London would die for. It also carries 3 times the number of passengers per hour that London does. The seating is OK for short journeys. I used to commute on it. Hong Kong is worth visiting just for the experience of its transport systems. The shopping is pretty good too.

Can only second TP - I used it for 6 months in '95, and I can confirm that the MTR is second to none in terms of reliability and efficiency.

I did say the bobble strap hangers existed only until around 2000? :/
Off-topic but:
It seems to be a trend that the British people like soft cushions while Asians tend to prefer harder surfaces. The beds and sofas I've used in Hong Kong, Japan are far harder than ones in the UK, which I find very soft! Thus the MTR can get away with metal seats which are easy to maintain and durable!
I can put up with those metal seats for around 30 minutes. Lack of quality? The interior fittings feel more solid than the refurb jobs done in LU

I thought Hong Kong was great along with its metro. Having said that, I'll stick with my A stock -I wouldn't fancy doing Northwood-Aldgate it that!

MTR's DVA is excellent and the fares are relatively cheap. The Octopus card was one of the first of its kind. The seats aren't too bad. Most commutes in HK are up to about half an hour.

Not only the excellent DVA but the 'moving map' line diagrams are a great help too (just visible in the pic). These are the things proposed for the '92Stock I recall but abandoned before installation! New Yorks' recent deliveries of R142, R143, R160 all have a similar gadget.

Indeed. I must point out that the R160s use an LCD screen that whose info can be modified anytime. HK uses the older style due to its simpler routing patterns and aforementioned reliability.

Regarding the changeover between 83 and 96 stocks. Was this a gradual process? I remember going to Wembley over the course of a year and, on one occasion the Jubilee was all 83ts, the next I was surprised to see completely new stock. What was the overlap?
Has anyone got a picture of them working side-by-side? I've certainly never seen one myself.

It was gradual but there wasn't a great deal of 1983 stock to replace in the first place.
The first 1996 was delivered July 1996, with trains entering normal passenger service (as opposed to a Stanmore - Wembley shuttle) on 6th January 1998. Full conversion was achieved with the 1983 stock withdrawn on 9th July 1998.
Stock delivered after that was left at Stratford Market until the extension opened.
[the dates are sourced from the 'Jubilee Line' by Mike Horne.]
