The first train entered service way back in November 2023! So if the second train arrives in September, that will be ten months. That makes the FoI forecast of no more new trains this financial year, to March 2025, quite believable.

At that rate they should have the rest of the fleet finished by Christmas.

On Saturday a member of the CLIP team posted on Facebook 'Central Line Past & Present' Group the train has been through software updates and "will be … off to Ealing for routine brake testing."I saw a 92 stock in Ealing Common yesterday at about 12:30, parked on “the alps” (the sidings close to the transport museum depot). I was on a train and my slow reaction time meant I only got a photo of its roof! Is this the first CLIP train? There was an unusual train in the timetable with timetable ID 776 and leading car ID 6246, which I thought was the 92 stock, but I suspect that’s not right. |

I think the CLIP train is currently sitting in Hainault depot for further works.
A 92 stock was at the South Ealing test track, not long ago. That might have been the one you saw.

Can anyone contribute an update regarding the proving of the 1st train + the next trains?

I was on the visit to the CLIP project at Acton organised by TechSoc last week. Testing of the first completed train is continuing. This is actually known as Train 3, with Train 1 having had only the replacement traction system, and Train 2 only the new passenger info systems, as trial runs. Train 3 is the first with everything fitted. They were working on Train 6 during the visit, and aiming for an eventual 50 day turnaround time. |

Further info for anyone interested
Train 1 & 2 were prototypes, so were stripped down and being built into the 'proper thing'
Train 3 is heading for the South Ealing test track (Currently stabled in Northfields depot)
Train 4 should be ready soon
No word on train 5 yet
Train 6 as you said, currently in the works

Thanks for update
Sounds like Acton works is full (5 trains) which are in various stages of progress but not in "full flow" yet - not sure if this is pending design sign off, staffing levels or materials?

Yesterday I was told that the CLIP train is currently stuck in Ruislip depot and can only move in Restricted Manual (15kph). I have no odea how reliable that information is as mess rooms are notorious for rumour and gossip

CLIP Train 3 91001+91201 has been on the South Ealing test track for the past few days, stabling at Northfields and Ealing Common

I hope the testing was successful - any idea what it was about?
Rather an unexpected time in the program to do the Brake performance Testing.
Noting that I don't think South Ealing is Central Line ATP or ATO equipped

Speculating here but previous testing might've identified tweaks necessary to the software which, once done, needs to be tested to prove performance is as predicted. This wouldn't necessarily need ATP or ATO - just controlled & measurable brake applications under the right conditions. I may be totally off-beam but if so hopefully some more knowledgeable person might want to contribute.

It's worth noting only one CLIP train is in service at the moment
As I said in late March, the next CLIP train is expected to enter service in December

Does anyone have an update on the plan and whether they have indeed had to start a separate work stream for essential heavy maintenance/overhaul works on "standard" 92 stock so they can remain in service pending their turn in the CLIP queue to Acton. With regards progress on the CLIP trains - I hope by now the first (train 3) has completed testing (at South Ealing) and has returned to clocking up in service/proving mileage. It seems the next completed fully refurbished train is due to be available for service in Dec 2024. |

One of the key reasons for the long gap between the first and second CLIP trains going into service is that there is a separate Door Overhaul and Programme lift project ongoing in 2024 into 2025. This programme had to be separated from CLIP, because the pandemic delays to the programme would have led to the (non-CLIP) trains running out of their 'certification' had the two work elements remained integrated as had previously been planned.

I suppose that is what the second line of my quote from the TfL Commissioner’s report - July 2024 in my post of 17 July was all about! Two lines about overhaul of Central Line trains, but about two different programmes!

There’s pictures on Facebook of ‘Train 4’ (which is, of course, the second to be completed) being moved from Acton Works to Ruislip by road, ready for whatever they need to do at Ruislip before entering service, due in December.

Thanks Jim, that’s my FOI request but I read the answer here before noticing the email from TfL, sent yesterday.  My request was “What are the latest forecasts for the numbers of CLIP-upgraded 1992-Stock trains completed or entering service in each financial year from 2024/25 until 2029/30?” And the reply was CLIP trains in service: 2024/25 - 2 2025/26 - 9 2026/27 - 25 2027/28 - 45 2028/29 - 65 2029 - 85 So the aim is for Acton to ramp up to about 20 trains/year after the first few are completed. As Jim says, the table does not include 2030, consistent with the previously stated aim of completing the lot by the end of ‘29. If you reshuffle the above figures slightly I guess the aim might be for capability of producing 20 per calendar year from Jan ‘26 onwards. We’ll see. The TfL Programmes and Investment Committee papers for 3 October 2024, item 11: London Underground Renewals, shows under table 8 – Key Projects to be completed in 2024/25: "five CLIP train and overhauled trains will return to service." This is more than the two forecast for the year in the FoI reply, but not clear that they are all CLIP trains with overhaul, or some CLIP and some overhauled makes five! After all, CLIP has again been redefined to split out overhaul as a separate process in view of slippage in programme and some trains needing more urgent attention. CLIP full production rate by March 2027 is still forecast, but maybe the completion date has also slipped in view of slow start? Strategic milestones in the TfL Investment programme report Quarter 1 2024/25 (1 April to 22 June 2024) includes: shown as due Jan 2025, but expected in Dec 2024. |

Is the original CLIP train back in service yet? The last report above was brake testing on the Picc test track a couple of months past.

Currently sat in a depot (not sure if it's Hainault or Ruislip?) depot for door works. Won't be in service for the rest of the month.

Has the train actually been "exercised" enough yet to prove the upgrades/fixes undertaken this summer ?

A member of the CLIP team posts occasionally in the Central Line Past & Present Facebook group. He recently commented on a photo of the first train in service, saying it’s been in regular service use for both testing & training, but the door overhaul (not carried out as part of the CLIP works) and more software updates were now due.
A recent post also said “We’re coming off it soon and it’ll be on its own.”
If the lessons learned from the first one’ve been applied to the second one, now at Ruislip and due in service in December, it’ll presumably need a shorter testing & commissioning period.

A recent post also said “We’re coming off it soon and it’ll be on its own.” I was told they were! How things get twisted so easily... Good news that the CLIP train will finally be on its own. I've also been hearing that after this month (as miff said the train will be out of action this month due to software updates) we should be seeing it more often but take this with a pinch of salt I don't actually think it's done the run up to Epping in passenger service, nor the Ealing Broadway leg. I would imagine that would be the next step once more paths are implemented. |

Good that the 2nd CLIP train progressed to Ruislip for the remaining works - that also explains the carriage I saw last weekend trundling up the West End Road.

CLIP is intended to upgrade the 92ts fleet to improve reliability and extend its life for another 15 to 20 years. The first train doesn't seem to have seen much public service in its first 10 months. It's still a couple of months before the second train arrives in service. I presume that will be the first real test, having built on experience from the first train. Production is due to ramp up in the coming financial year.

extend its life for another 15 to 20 years by when LU might need to raid museums for compatible computer tech for the signalling! |
