Latest update from TfL Board committee papers (page 34)

Introduction of the new DLR (B23) trains
Two new DLR replacement B23 trains have been delivered, coupled and commissioned at Beckton depot. Next year, we will carry out testing to secure regulatory approval so they can enter passenger service. We are also able to confirm that we will be receiving 11 additional trains to supplement the original order of 43 trains. This means a total of 54 new trains are planned to be introduced from 2024, with the full fleet installed by 2026.
The new trains feature a walk-through design, latest audio and visual real time travel information, air conditioning and mobile device charge points. In addition, the new trains have a 20 per cent greater capacity than the existing trains but being only seven per cent heavier, giving lower energy consumption per passenger. The trains also have improved accessibility with a variety of seating types, large spaces for wheelchairs/ mobility scooters, and helpful lighting to indicate open/closed doors.
When all 54 new trains are introduced by 2026 it will help boost overall capacity by more than 60 per cent.

One of the contractors that have been updating Beckton depot for the new trains has collapsed, which will probably cause further delays to entry

New DLR trains on track, but depot expansion faces delays after contractor’s collapse​

Upgrade work on the DLR to prepare it for a fleet of new trains has hit a problem after one of the contractors closed down.

The depot and maintenance facility at Beckton needs to be expanded to store and look after the new trains that will be coming into service next year, so there’s a large project to redevelop the depot. Most of the work is being carried out by Morgan Sindall Infrastructure, who are building a new maintenance shed and facilities, but a project to rearrange the railway tracks to create more space to store trains was contracted to a rail specialist.

That company, Buckingham Group Contracting (BGCL) had been awarded the contract to build new railway sidings but had suffered from recent losses and cashflow problems and eventually had to bring in administrators to salvage the company.

BGCL suspended works on site and stood down its subcontractors. In the short term, the TfL team enacted a safe stop to ensure the site was left in a safe and secure condition.

Some of BGCL’s assets were successfully sold, but the rest, including the part of the company carrying out the DLR depot upgrade, couldn’t find a buyer, so they were closed down and the staff made redundant.

TfL said in a recent report that “work is ongoing to develop and consider options for how we complete these works.”

Although new trains are due to enter service from next year, the full fleet won’t be in use until 2026, giving them time to complete the depot capacity upgrade.

The depot expansion at Derby Etches Park has also been affected by the BGCL collapse.

I really am surprised by the increased extent of weekend DLR closures, which are described on posters as being principally due to "testing the new trains". Apart from those recently experienced, in December every weekend one or other of the lines through Canning Town is impacted, and for the first one, December 2-3, every line there is closed the whole weekend. Now the DLR concession operator before the current one certainly had it in their contract there could be only one weekend closure of each branch per year, but now it seems to be open house.

Speaking of Canning Town, nice shot of unit during testing there:

It looks rather smart if you ask me.

I'd agree, very smart. Is it just me, or did anyone else get seaside resort vibes from that photo? It looks like it wouldn't be out of place in somewhere like Santa Monica, for example.

The whole of the "City Island" area just across the River Lea from the station has been nicely rebuilt.

Ah yes, now you mention it I can sense the Paris Metro vibes too. It's been I think nearly 16 and a half years since I last went to Paris, a fact your post has reminded me about and I think it's time to look seriously at a return.

I'm definitely looking forward to these new trains still, they've got plenty of promise!

Although 25 trains have been built and they don't enter passenger service until March 2024 (per TfL Board papers)

Rumours are TfL are starting to thin out existing fleet, ahead of new fleet being ready, with B92 set 88 leaving on 13th Nov, and B90 set 38 leaving 2 days later 15th Nov, both going to CF Booths at Rotherham.

Has anyone else heard if these rumours are true and fleet will be leaving at 2 day intervals

Is that wise given Xmas passenger numbers are normally extremely high. How much slack does the fleet have?

Losing 8-10 units by Xmas seems high. It's then quiet until mid Jan when numbers rise quite a lot once again.

Unless they're confident they can get some new stock in service earlier.

The only units that have left for scrap so far are the ones that are long-term out of use. As far as I am aware, there won't be any more leaving after 88 (long term out of use) and 38 have left. There is no increase in service or units used over the Christmas period when compared to the rest of the year

One thing I'm curious about is if these will fix the fairly bad hunting oscillation you get on the current stock

I've read various reports that a clever suspension design is supposed to reduce it.

So the B23s are meant to be going in service this year, I wonder what date TfL have in mind?

Despite closures on the system every weekend through December and now into January, nobody I know has seen a single one out on the line, which is what the posters claim is the reason for this.

The existing trains seem to have been allowed to "let go" for maintenance, external corrosion underneath the windows can now be seen noticeably on several units, which have never shown the slightest deterioration before.

The hunting is apparently a feature of the way the tyres are turned, to handle the sharp turnouts. I actually recall it being pronounced at certain points on the system opening day back in September 1987.

I live right by Stratford International and I've seen them out twice - once leaving Stratford Int'l and once after leaving Pudding Mill Lane (I was on a Greater Anglia train going past, so didn't get a picture). I do agree that the old trains seem a bit more worn down though, but I suppose TfL doesn't want to invest much in keeping them decent if they're off to be scrapped soon.
