2024 Tube Stock (Siemens Inspiro London)

[MaidaVale]

I believe the first unit is in service soon.

I saw an Xtrap 2 testing at Flagstaff in mixed traffic the other day with the seat plastic wrap removed and all the doors opening (with staff at each door) so looks likely soon.

I'd imagine it'll be quite a few more months yet until the 24 Stock are at that stage in London. When they are being tested during traffic hours or having driver training done on traffic hours, I believe the plan is still to do so on the short Northfields to Arnos Grove services for the most part, and then keep them mostly isolated to that pattern even upon entry into service until enough drivers have been trained on the new stock to a point where it won't cause any issues during crew changes or service reforms during disruption.

The next significant step is probably running test trains during off peak hours Northfields - Acton Town or Hammersmith.
Certainly need to consider how they handle crewing of the new trains once they enter service - it has and continues to be a real problem with the central line refurbished trains, which continue to run only a fraction of the milage they should be doing

38063-48063 has successfully made its way from Europe to Goole, arrived today.

Managed to take a pic of the new wheel lathe building at Cockfosters depot this week. Quite obviously not completed, and nothing inside either.
(Pic shows exterior shot of an empty building clad in blue and white panels.)

That set was in Düsseldorf last Friday!

The cab is rather small and cramped, but they look smart.

Even after moving the partition wall back (at the expense of 2 or 4 seats)?

Yeah, the cab may not be big compared to modern national rail stock but is it bigger than modern tube train cabs, certainly looks bigger than 73 stocks.

What are the two holes in the bottom rubber stip for on the windows? I've seen the same holes on class 165 Chiltern Railways windows.

After a bit of research I think they might be weep holes.

From what I saw, yeah.

Yesterday I was having a read through the TFL board meeting which was on the 18th March and from the document it said that the target for the new Piccadilly line train to enter service would be on the 31/12/2026

 

[Central]

Think when they eventually enter service,initially they’ll be on the Arnos Grove-Northfields service only.

Think when they eventually enter service,initially they’ll be on the Arnos Grove-Northfields service only.

As of the January timetable change, this service pattern no longer exists - and the January TT has been written with 24TS introduction in mind.

 

[Zeremony]

Current service pattern:

Cockfosters to Heathrow
Cockfosters to Northfields
Arnos Grove to Rayners Lane
Arnos Grove or Cockfosters (peaks) to Uxbridge

All are self-contained diagrams.

It is bigger than a 73 cab but the dynamics are weird. There isn’t a massive area to get in and out through the side cab doors (particularly on the drivers side because of where the seat is) and the instructor side console comes out miles. Plus the windows are very small, the M (front) door window is recessed quite a lot too. I’m not sure how the sight lines will work in practice, or how much more needs to change out on the line, seeing as in more than one location the legacy station starting signal is before the 24TS stop mark……

(Image shows a view of a 24 stock cab taken from the drivers' side door, illustrating the narrow space between the seat and rear bulkhead.)

 

[Old Walter]

That’s the one! It does slide forwards but not by a vast amount. The room behind the seat, the small windows, the restricted sightlines……..wouldn’t 200 years of experience of designing trains be handy…..oh wait : 0

I just saw a video of one posted by Rail Color on Instagram on the Continent (due to the Continental European electric locomotive) showing it being hauled by a RailAdventure locomotive. It had graffiti on it. Who is responsible for the cost of removing the graffiti in this case? Presumably it doesn’t belong to/hasn’t been handed over to TfL yet, so it still belongs to SIEMENS. I guess SIEMENS has to hand it over to TfL with presentable paint-work and windows. If it was done while it was in the custody of RailAdventure (it had left SIEMENS’ facility), does RailAdventure cover it (presumably maybe through insurance, or something like that)? Or would they have some clause in the contract which states that they wouldn’t be liable for any damage which they didn’t directly cause themselves?

Yes Ken Livingstone once launched a competition for ideas on how to add AC to the deep tube. There were no winners, but the favourite idea was adding heat packs to the end cars that would be swapped with cold ones at the terminal stations

I believe that in early 20th century India, ice blocks were installed in certain carriages with a fan blowing across them as a primitive form of a/c, and would be regularly replaced en route

Is there another Goole-Old Dalby working today? Two 57s have worked to Goole on a 6Z22, and there’s a STP 6X22 in for this morning, although not activated yet:

There do seem to be some test train movements Cockfosters - Northfields (Infrastructure work going on towards Heathrow)

 

[davews]

I am puzzled though by Journey Check which reports 'Piccadilly Line closed Cockfosters to Heathrow Terminals, good service rest of line'. Does that mean only Acton to Uxbridge is open?

 

[Dstock7080]

That is indeed correct
Acton Town-Uxbridge every 20min
Acton Town-Rayners Lane every 20min

 

[Alxxxs]

Approaching Hammersmith

 

[jumble]

We went for a walk around Ealing today
Saw the 24TS passing Acton town both in the morning and afternoon
It is not exactly hard to track where they will be

Here's 38030 leaving Northfields and 38062 arriving back from King's Cross on Sunday.

An unpopular opinion. A common complaint about the 24 stock are its small windows. I admit they are narrow. However I also think tube trains usually look better with the smaller or shorter height windows of modern stock as well. A modern tube train with s stock style windows makes me imagine a modern 1972 tube stock look alike accept I think it would look fugly, like some typical ai interpretations of tube trains.

The number of people who have actually seen the the 24TS stock in the flesh, let alone travelled inside them, is very small, so to describe a limited number of snap opinions as 'common complaints' is misleading. Apart from considerations of rigidity of the cars that, apart from the very ends have no full bulkheads requiring the sides to maintain their form in the event of a collision, there is the issue of thermal performance. Over half of the Piccadilly line, like most of the deep tubes, is above ground so 92TS or even 73TS style windows would present an unnecessary load on the AC, which would be highly compromised by the limited space on board.

That’s great. But windows are about more than just thermal performance or aesthetics. If they’re too small, they prevent people from seeing out of them if they’re outside the range the designer considered because people’s eyes are above the top of the frame. That’s why I actively avoid Pendolinos, and will be a particular issue for standees on the Tube.

I can barely see out of the windows on most current tubes, and I'm only 5'7"! Given that they'll have a modern PIS telling passengers where they are, I don't think standee window visibility is a big issue. Especially as you're more likely to get standing customers in the busiest sections, which tend to be underground anyway.
