I thought LCD displays were a thing of the past, didn’t the 1973TS refurb the 1995/96TS and originally the 1992TS use unreliable yellow segment for their exterior LCD destination indicators? They were unreliable and especially on the 1992TS, being replaced by LED displays form the mid to late 1990s. Tube Lines replaced the examples on the 73,95 and 96TS. The Networker trains also had green segment LCD displays, they were replaced again with LED ones akin to the 1992TS, the LCD segment displays deteriorated quickly, I recall it was due to sunlight degrading the segments?

Do the Aventra trains and pretty much everything else have TV style displays? What type of displays are they?

== Doublepost prevention - post automatically merged: ==

With the 2009TS about 15 years older than the 2024TS by the time it finally enters service, the contrast of modernity will be immense. I find the 2009TS quite similar externally to the 2024TS, the shape of the door windows and the front is somewhat reminiscent, of course the 2024TS is much more modern and looks a better train than the 09 Stock. I fear the 09 Stock may have an early replacement as it will seem so old and outdated once 2024TS is rolled out across the entire deep level lines in the next 10 to 20 years. The lack of walkthrough carriages and outdated scrolling DMI indicators and more importantly air conditioning, will make the carriages stand out like a sore thumb compared to the 2024TS or similar varieties.

You are correct in that LCD segment displays are a thing of the past. The thing replacing them were LED dot matrix displays which could display text in a very readable manner and didn't suffer from burn-in unlike its prior counterpart.

Most of the rail industry have now moved onto LCD panels which is the same tech behind TVs and computer monitors. This is what is on the in-carriage screens for Aventras and the 2024TS.

Continuing the chat about display types, Desiro's use another type of display for the external destination displays, the flip-led display. These are a hybrid of the mechanical flip-dot/segment display (like the Family Fortunes display) but with and LED for each element. This makes them readable in bright sunlight without needing extremely bright LED's.
Work really well in my opinion.

Had a look at the maps in the TfL Board papers regarding compulsory purchase for servicing depots for the 36 Bakerloo trains, and sites appears to be :

1) the area currently used by Travis Perkins at Queens Park. Basically the long site between Bakerloo tracks and WCML all way back to ramp off Chamberlayne Road

2) Northwest of Stonebridge Park depot, alongside Wembley Brook, a sort of triangular site alongside WCML towards Wembley Central

I noticed new cameras at Finsbury Park, presumably to feed the in-cab monitors? They're hanging on new gantries alongside the existing ones, a similar shape/size.

Correct, a fair few have been incorrectly placed (blocking the old cameras) and have been reported and moved.

When did these start appearing?

Is that Turnpike? These markers and the 24 stopping diamonds on the track have been appearing over the last 12 months - I think I posted about one in Wood Green some time ago. Hopefully the removed roundel in your pic is in the London Transport Museum at Acton....

Yes it's amazing the amount of kit that is required for the new trains "system" ( and has to be installed and proven before they can enter passenger service)

Noted in the yard at Gascoine Wood this week was what appeared to be an underground unit. The facility has seen visits by 730 units for mods etc. but this seems to be an new venture. Does anyone have any information on what's going on? TIA.

Believe this is being used to store completed 24 tube stock for the Piccadilly line.

Can anyone confirm which set moved from Goole to Old Dalby on 25th June?

Headcode for the transfer was 6X26.

TFL app appears to be showing when the Heathrow trains will be passing through the stations (Turnham Green here)

48030 made it to Terminal 5 today. I saw pictures, but they all had faces from the testing crew so won't post. A good milestone though.

Also testing was taking place on the 'local line' between South Ealing and Acton Town. This is a regular testing track for lots of stock and allows for wet testing, with a water spray (which is the white mist in the shots below.)

(Pictures show a 24 stock progressing along a track with a mist water spraying onto the tracks)

Apologies, the quality is low as it was a screen shot of a WhatsApp message and I don't know who to credit.

It was impressive watching the brake testing take place today. Here's a video I captured demonstrating the stopping capability in wet conditions.

The American company, Aecom, has been appointed to do a feasibility study into additional stabling and depot capacity for 2024 stock on Bakerloo

American infrastructure firm Aecom has been appointed by Transport for London (TfL) to deliver a feasibility study for the depots and sidings required to facilitate the Bakerloo Line Upgrade (BLU), marking one of the first steps towards the rollout of a new fleet of trains on the London Underground line.
The appointment forms part of the feasibility, planning and optioneering work needed to enable the introduction of new rolling stock on the Bakerloo line, replacing the existing fleet that first entered service in 1972. The trains, which are now more than 50 years old, are the oldest in daily passenger operation in the UK.

The programme is intended to support the introduction of the new fleet while delivering long-term improvements in reliability and passenger experience on the line.

As lead consultant for the early-stage feasibility and planning work, Aecom, supported by Arcadis, will lead multidisciplinary delivery across planning, systems engineering, rail disciplines, environmental services, digital delivery and building information modelling (BIM) integration. The work will culminate in a coordinated baseline design covering Stonebridge Park Depot, the Queen’s Park area and the London Road (Elephant & Castle) sidings.

So TfL are paying the Americans to do a feasability study that will tell them what they already knew 10 years ago.

I feel like a slow clap for government efficiency is coming on.

You would have liked to think that TFL and previous consultants had got the requirements and dependencies understood ( been a lot of rumours of need for blockades) .
But perhaps not clearly documented and ready for the commercial project structure envisaged ( lessons learnt from PLU).
Let's hope the framework arrangement with Aecom works well and they don't take TFL for a ride

In this country we spend more money and time on "feasibility" studies, consultations and all sort of other paperwork than some other countries spend on actual rolling stock production or infrastructure construction.

Roll on "consultation nation".

Presumably TfL don't have any in-house architects/civil engineering any more so they have to use a consultant? Calling it a feasibility study when it's going to produce an actual design seems a bit inappropriate

They do have in house civil engineers but they are obviously specialised in day to day operations etc. It isn’t economical to employ enough people to do a feasibility study this large that only happens once a decade.

Aecom is the same company that has been appointed for the Bakerloo Line Extension Stations & Elephant & Castle, and they've been appointed to the DLR's Beckton Depot Upgrade (which has presumably been completed), and I haven't heard anything negative about that so presumably they're not too bad.

The title is clickbaity and misleading. In reality they're doing more than just a feasibility study:

"As lead consultant for the early-stage feasibility and planning work, Aecom, supported by Arcadis, will lead multidisciplinary delivery across planning, systems engineering, rail disciplines, environmental services, digital delivery and building information modelling (BIM) integration. The work will culminate in a coordinated baseline design covering Stonebridge Park Depot, the Queen’s Park area and the London Road (Elephant & Castle) sidings."
