Point to note re the upcoming comparisons of S Stock and 24ts:

They will be roughly the same age difference ( 13 to 15 years) as there A Stock and 73ts were. Did the 73ts feel generations ahead of the A Stock when new?
Same with 1967ts to 1983ts. But 1992ts was just 10 years apart so I think this type of thing isn't linear.

A more apt comparison might be 1996 Tube Stock, and S Stock.

These are some pictures of them at Ealing Common depot from yesterday https://www.facebook.com/share/r/1AFYN1HVY4/?
To me when I see the interior it definately doesn't look claustraphobic despite the small windows though the door windows allow a lot of light in. I think the rubber trim at the side of the doors remind me a lot of S stock, vibewise, also the seat armrests.

^Yeah they seem much brighter than in videos where transport influencers like Geoff were invited to ride the trains on a press ride.

Yeah probably. I wonder how different it would look in real life. The destination signs in recent pictures also looks clearer and brighter.

Wouldn’t be surprised if they’ve done some tweaks since the press event. Remember that the trains haven’t entered series production yet, and this initial batch are still technically prototypes at this stage.

A good example of this are the doors at the front of cabs, the unit at Northfields doesn’t have the final design which has a cover over the TIF brake interface.
Here’s the final design:

I agree that the train that was shown to journalists was probably first off the production line for testing purposes.

What is a very rough timeline for the completion of the Picadilly line trains production at Goole? My calculations based on 2009 stock (~45 trains manufactured from ~Dec 2009 to June 2011) indicate that it may be some time in H2 2026 considering the start date in March 2024. However, I appreciate that I am likely missing more specific actual up-to-date production figures. I would suspect that the production rates are quite a bit slower vs. the 2009 stock due to 2024 stock still having quite a few months before it can even enter the service

Additionally, there were two ’pre-production’ 09TS built for Metronet before the main fleet. I’m not aware of any dedicated prototype or pre-production 24TS units.

For financial products they usually say something like "past performance is no guarantee of future performance". This certainly applies to train construction!

Have to wonder if these pre production units will share the same fate at the 09TS ones.
Can't imagine all of them will considering there's already been 4. Maybe the first 2. Then again in this economy would it really be wise to just scrap them? I think they'll probably be some of the last ones to enter regular service as they undergo modifications to match the serial production units.

Were the 09TS pre-production units completely scrapped? I thought they were modified/rebuilt as 001-004? Or are 001-004 brand new units?

It depends on your definition, not brand new, some parts were new, many other parts were reused. Although I think refitted or reworked would be usual way of describing them

Even if you got a new body shell and transferred most components over then wouldn't call it brand new, probably use term rebuilt.

Prototypes are usually reworked to make them the same as the serial units.

001-002 and 003-004* are brand new bodyshells at the end of the run with some component re-use. The original 001-002 and 003-004 spent many years at an MOD site before being blown up (literally).

003-004 were modified to production standard.*

It is also worth saying that whilst the S stock had two pre-production units (001-002 and 099-100), these were modified to match the production run rather than being replaced (with the exception of the traction packages on 099-100, which remained unique but at least one of which has now been replaced at overhaul). I would suspect the 24TS will be more in line with the S stock than the 09TS.

*Apologies for some duff gen, I was misremembering the status of 003-004 which were also new-build. In true LT fashion several renumberings took place which is a lot to keep track of! Check your reference materials first :lol:

Interesting. Was the bodyshell of 001-002 significantly different to the production ones that they couldn't modify it?

The bodyshells themselves weren’t that different, but various modifications were made and the fit-outs differed significantly from the production versions. Ultimately it was cheaper to build two more production trains on the end of the order than modify them.

My previous post also edited, as I had misremembered the make-up of 003-004.

Somewhere, not in London
Also fun to note that any prototype mods and whatnot also being done on the 2nd versions of 001, 002, 003, 004 means that they were the lowest mileage units for quite some time. (Given how challenging ATMS was to fit.)
