They'll be able to charge more for the line being a museum. Seriously though if that ends up being the plan there will be a fairly hefty and expensive refurb needed at which point you'd have to ask if it's not more cost effective to bring in new trains.
They had a refresh (seat coverings and flooring) only a couple of years ago.

They're getting new PAs and digital screens, new lighting and wheelchair bays added as we speak.

That was a lot more than a refresh. Major corrosion repair work. I really don't care what is being done they still look old, tired and neglected and massively past their best before date.

I know they are old but I really like these trains... Luckily some will be preserved... I much prefer them to the 1992 and 2009 stocks

You do wonder how much they can patch and repair corrosion before the carriages wouldn't hold up in a crash anymore...

It's not the case of holding up in a crash - it's a case of holding up in day-to-day service. That's why the heavy welding work was done on the 72 stock.

Theres a chance that the trains for the other 3 lines esp for the Central will be slightly different to the Picc ones. The Central trains will have 11 carriages rather than 9 for the Bakerloo and Piccadilly lines

Today, Siemens’ social media accounts have presented the final design of the new Piccadilly line tube trains.

View attachment 91843

Here is the press release with a lot of information and a few pictures, outside and inside: https://www.mobility.siemens.com/gl...nces/metro-london.html?linkId=300000000971683

As well as a datasheet with some technical information: https://assets.new.siemens.com/siem...ity-piccadilly-line-tube-train-data-sheet.pdf
I notice that the power is given as 2500 kW. That seems an awful lot...Like having a Deltic on the front..

They are designed for meeting the demands of ato with a full load. Additional power doesn't add significantly to the tare weight and it doesn't add to the energy cost when not used.

However it does add to the cost of the infrastructure, the Piccadilly line is having to have power supply and conductor rails upgraded to handle it. The 21.6km of composite conductor rail cannot be cheap as it needed approval by the Commissioner. (per TfL Board Committee minutes)

Approvals by the Commissioner
6.1 Since the last meeting of the Committee, the Commissioner has approved three Procurement Authority requests in respect of matters within the Committee’s remit. These related to: Piccadilly Line Upgrade Track – Manufacturing Contract for 21.6km of Composite Conductor Rail and Accessories; London-wide Ultra Low Emission Zone (Road User Charging 2023 Scheme) – Drawdown; and the variation of the Managed Services contract to cover additional business critical changes to the SAP system.

Then again, the power supply, distribution components and traction equipment will be running well within its capability for more time, ensuring longer service life. So that will mitigate some of the additional capital cost with a lower running cost as well as providing smoother speed profiles and better disruption recovery.

Maybe I'm weird but as a teenager I used to deliberately ride in the Standard stock trailers, as the noises were more fun.
Yes I remember thos on the Central Line. In the end cars, there was the grind/whine from the drive pinions and the clunky stepping up of the contactors. In the trailers it was the wind up and down of the donkey compressors after every stop.

although off-topic for this thread, Standard Stock compressors were in the equipment compartment behind the driving cab
I'm talking about the Standard Stock trailers that were converted in 1938 to run with 1938 TS on the Bakerloo. There were fifty-eight of them, and they were known as '58 stock'. The first was withdrawn when it telescoped when a 1938 train had an argument at Watford with an LMR train of the later TOPS class 501, and the last in 1973.

Absolutely. I was on the Bakerloo line last night and the trains felt decrepit.
The LED lights and new flooring on some make a big difference. Throw in the latest RVAR refresh and it’ll help with the appearance, but the trains are janky when they’re on the move for sure.

Ultimately even if they get funding, it’ll be early 2030’s before the last one is withdrawn. Can’t imagine what state they will be in by then.

I don't' suppose replacement stock on the Bakerloo will have transverse seating?

The proposed version for Bakerloo is virtually identical to those for Piccadilly. It is just a partially different colour scheme in the saloons, and different version of signalling safety scheme (although initially both look likely to use existing system).

It would be very easy to divert the Piccadilly growth build (the increase from 24tph to 27tph) to the Bakerloo if done within next 3-4 years. Similarly could build more for Bakerloo, or even build extra for Piccadilly after a Bakerloo batch.

The version for the Central are planned to be different, 11 car (6 single cars with 5 suspended links), and different length bodies.
