Suppose it may also be important to mention that if I recall correctly, at one point in time, there was going to be some form of introduction of a refurbished 92TS on the 26th February? We aren’t far from that day at all!

Well I take it that it’s not happened today then as no one has mentioned it.

Oh yeah it was march. I forgot there was a typo in the comment about the two dates regarding the two dates. Think the other one was 30th march.

"Pull-forward" seems to be 'newspeak' for doing bits of a project that are not being delayed and can be done independently of the bits that are delayed. Appearing more widely across various projects recently. Of course it doesn't usually mean they are pulled forward, just much less delayed.
Bring forward would be a better term. If you can push something back, surely the opposite is to pull it forward? I'd expect something pulled forward to be completed earlier than originally planned. |

Apologies if already asked - but will the refurbished trains need the signalling system to be modified in anyway, if so, how?

Whilst the 92TS is quite unreliable, the signalling system on the Central is actually pretty robust hence I don't think any modifications are being made to the signalling system

In broadcasting jargon, 'pulled' is used for an item removed from the schedule.

"Progress continues on the Central line signalling life-extension projects, with design work continuing for the obsolete systems. Plans are maturing for installation of assets on site in Quarter 4 2022. These works will utilise both internal delivery and our contractor installing assets at different sites to ensure efficient delivery. An outline specification and design has been completed for an enlarged testing facility at Ruislip depot to support the renewed train borne signalling equipment through its life."

Unsurprisingly, the Investment Committee report provides a snapshot without actually explaining exactly what they are doing. My understanding is that the functionality and interfaces will be maintained and obsolete components will be replaced with new ones with the same function. So not a resignalling.

"The Central Line Improvement Programme is a complex project aimed at improving the performance, reliability and accessibility of all Central and Waterloo & City line trains. The Programme includes a complete redesign of the train’s control and diagnostics computer and new traction motors, allowing accessibility improvements including wheelchair bays, CCTV, a new passenger information system, as well as new seating. Under the Programme, we expect the first refurbished train to enter customer service later this year. We are currently carrying out refurbishment works on multiple trains at our purpose built facility and expect more trains to enter customer service in 2024, with more to follow in the years after."

Everything about CLIP (or indeed, eventual replacement of 92TS, has been "rather vague"!

Pretty sure I recall tender reviews or concept design stage back in 2016 0r 2017. Seems to be taking longer than a new stock project. Still, I hope it all works out well though.

So the 26th March date for the first train into service probably isn’t happening then.

a slight update:
Train 2 already has the internal CLIP fittings, being the prototype for these.

Body end replacement? And how bad was the corrosion?

If all trains have to have repairs for floor corrosion and body end replacement the programme of work will take at least 2 to 3 years before all Central Line trains have gone through Acton Works. Of course Clip Train 2 is a first to go into AC15 and the next train may take less than 12 weeks to complete.

Woah. So does that mean another 3 months minimum until the first train is done? I don't want to sound pessimistic here but it has honestly felt like for the past 2 years every date has been pushed back several months every time it draws close, almost as if the day will never come. I know this stuff takes time and I'm not eager for it to be rushed, but I am impressed how we were originally expected to have all trains refurbished by 2022 and it's now increasingly likely we won't see the first one in service until 2024 (I know covid had a big impact on this too). Surely at this rate the full fleet upgrade won't be complete until 2027/2028? By that point they could've started to roll out the NTFL on the central line and saved the money on refurbishment.

As has been pointed out several times on this thread> It'd be true if NTFL was likely to arrive on the Central before the mid 2030s....

I suppose it is important what isn't in the latest budget milestones for 2023/24, as much as what is in, and there is no mention of CLIP at all!

Not completely certain on how correct this is, but yesterday I was at Ruislip Gardens at around 3:50PM. A train was advertised on the Westbound boards as a “Special” service. When it arrived, the destination board said “Not in Service” on both sides and it did sound noticeably different, a lot quieter both when braking and accelerating (it stopped for about as long as a regular service would). Lights were off so I couldn’t see inside the train (thanks tinted windows!), but some emergency doors had been left open. Is there a chance I could have seen one of the CLIP trains out on a test run? I would have liked to see the inside to verify it were the CLIP train, but unfortunately I couldn’t, so I wanted to turn to some more knowledgeable people here who may know more than me.

Unfortunately not a CLIP train as none have been released from Acton Works.
it was T040 91253+91015 which detected a positive to earth fault approaching Northolt EB at 15.38. it was detrained and reversed via the east-end crossover in coded manual back to Ruislip depot, passing Ruislip Gardens at 15.49.

Hi everyone, I submitted a Freedom of Information request to TfL for photographs of the interiors of the trains currently undergoing refurbishment, and they got back to me with them today. I was wondering if I am able to share those photos here or if I would be breaching some kind of copyright/data protection thing? They've not yet been published on the TfL FOI page, but I assume they eventually will...?

Admin response
It depends on what conditions TfL have attached to the images, though if they have been released in response to an FoI request I can't imagine that they are "controlled" images so are fine to post.
