1973 stock withdrawal

[YSTrains]

Are there any plans for the first unit to be withdrawn? 2024 is not far by and the NTfL train will be delivered in spring.

 

[MaidaVale]

Not at the minute (that I'm aware of). Wheel flats are an issue more severe than usual at the minute so stock is a little bit short. I don't imagine we'll start to see the 73s being withdrawn for a good while yet, or at least until the 24 stock testing is well underway and T/Ops begin training on them.

My guess is from 2025 to 2027, no point withdrawing them before the 2024 stock arrrives.

One does wonder if the modern TfL will try and turn them into engineering vehicles, or just scrap them and then buy new trains for engineering vehicles at 10 times the price.

I imagine at least one will be retained for use as a RAT as the Piccadilly line just uses temporarily converted service 73s anyway. There's no plans for a signaling upgrade for a number of years, so the 73s should still remain perfectly compatible for RAT duties.

Given that a lot of ex-tube stock engineering trains have been scrapped the past few years can't see any real need.

Apart from the track recording unit (L132/666/L133) and the two Central RATs) there is not anything else. The ex D78 RATS are not tube size so don't count.

The MPU project stopped and cars scrapped, the Asset Inspection train project stopped, the tunnel cleaning train project stopped, and increased use of on track plant and road-rail vehicles, and, probably the most important, there are ££££££s for SFA at the moment. Engineers toys are at the bottom of the pile.

So what actual engineering vehicles is anyone else proposing we need ?

I suggest the whole lot will be reduced to scrap, except, as mentioned upthread, Picc. RATs (which seasonally exist already) + 1 car for Acton museum. And any other mug who buys any for use as a greenhouse, or classroom, or other equally non mobile project.

Remember now that a general use engineers train needing to run on more lines than the Picc, will need other lines ATP like CLATP, DTG, TBTC and CBTC. You are talking seven figure sums per train type to do that. Even if the Picc don't get resignalled for decades, to use 73TS as engineers vehicles elsewhere you'd need most if not all of that lot. You soon won't be able to get out of Ruislip at all without CBTC or CLATP. Does tend to limit scope. The Bakerloo no resignalling plans yet, but you can't get an LU engineers train there without entering from the Jubilee, hence needs TBTC; etc. etc for getting to and from all other lines. It all costs £££££££. And there is no realistic need for other engineers vehicles captive to either Piccadilly or Bakerloo.

Can the 73TS even run on the other tube lines, due to car length? Makes little sense to have Picc-only engineering vehicles.

Track recording car 666 is a modified 73 TS trailer car which operates on other lines already.

I assume the only unit withdrawn at present was the one destroyed at Russell Square on that dreadful day in 2005?

A few more have been lost over the years.

DM 888 was scrapped after a fire between Wood Green and Bounds Green in the early 80s.

The entire unit 204-604-404 was scrapped after a collision in Northfields Depot around 1990 (the actual damage was fairly minor, but the unit became a spares donor, and in particular was used to repair another collision damaged car, DM 170)

UNDM 314 was also scrapped at the same time as unit 204, having never entered service. It became spare after the associated DM 114 replaced DM 888, and T 514 became the track recording car.

Then of course there’s unit 166-566-366 which was lost as a result of the King’s Cross / Russell Square incident. It isn’t entirely clear at what point DM 166 was actually scrapped, as that detail seems to have been lost.

As an aside, the bodywork on the front of car DM 170 has an interesting history. It is believed to have originated from above-mentioned DM 888, having in the interim been used as part of the abortive repair of DM 204. So a small fragment of 888 survives to this day, having started on 888, then 204, and finally to this day 170. The piece of bodywork stands out, as it is painted a slightly darker shade of red than all the other trains.

Could some parts of withdrawn 1973TS be retained by TFL engineers to create a pool of spare parts for the continued operation of the 1972TS? As they probably have similar mechanical and electric components.

Potentially the odd bit or piece could be cross-transferable, but with all the changes over the years they're substantially different units. As a result, I find this unlikely on the most part.
