OK, so they were all built for the Met Railway or the Met and another railway but Preston Road is the only one now in Met line use.

Hmm, of these stations, Preston Road is the only one first opened in the 20th century. All the others are 19th century originally. Also Preston Road opened as a Halt with the impressively long name Preston Road Halt for Uxendon and Kenton.

How about Aldgate East as the odd one out, not being originally Met Railway. Presumably the loco is too obvious as the odd one out!

True enough. You'd need an ITMP for the 2 locos plus one Bakerloo line train scheme too though due to the formation being over length for the signalling's 138m limit. Not easy is it!

Don’t they get moved to the test track at South Ealing now and again? Yes, by the method I mentioned. Now and again is manageable. A full fleet would take a lot of careful planning due to the impact on Engineering Hours access to the railway for normal inspections and maintenance each time there is a stock move under an ITMP.

My understanding is that it is done under an Incompatible Train Movement Plan due to the 72TS not having Jubilee line ATP equipment. This involves no other train movement in the JL area so is quite disruptive. It will get worse when the Met line ATC is commissioned successively to Preston Road and Harrow and a similar provision will be needed.

Indeed. Planning and replanning several times in so many cases... For the postulated stock moves over LUL only routes, Test Train Operators would be the usual solution, having the route training and before the moves, the stock training.

I vaguely recall tube trains stored on a military railway at Shoeburyness, and maybe elsewhere, when there were too many for the LU network. Was this in preparation for the Jubilee Line extension before Stratford Market depot was available? I seem to remember JL 1996TS trains being stored at Long Marston rather than Shoeburyness, but maybe both were used. We also had several stored at LU depots including Upminster, Cockfosters (I think) and one at Edgware Sidings (my first ever trip there!). These would have been 3 car unit moves with the pilot unit which was a converted 62TS unit. The Upminster ones got heavily graffiti attacked so I don't recommend this sort of thing.

A: Entrance to Uxbridge Sidings. D: Northwood Sidings. C: Rickmansworth North Sidings from NB train?
Which would make B the odd one out, being Depot (Neasden), not Sidings. And link stabling places on the Met. Another odd one out could be Northwood, not regularly used as passenger train stabling.

The displays show the destination and all the stations where the train will stop.Some services omit stations How could this information be shown on the standard LUL displays? Agreed, not very well at Baker Street! Finchley Road DMI attempts to show the stops for the next train and the stopping pattern description for each train, but there's only one NB platform of course. The current DMIs at Harrow aren't a complete success at this sort of thing in my opinion.

The 62TS plus 92TS moves would have been 4-car plus 4-car. So within lengths permitted on the chosen routes. As mentioned in an earlier post, physical track layouts set the real limits for a very special rare movement. Signalling limits tend to set the reasonably practicable limits for moves that are to be relatively frequent like transferring a whole fleet over a period of months if special movement plans would otherwise need to be in place and cause extensive unavailability of Engineering Hours for maintenance and other new project works.

I used "a few years ago" because I couldn't recall the exact number. I agree it was well before CBTC at Baker Street and that the raw info source has been changed. I was thinking more of the screen's display layout, colours, font and so on being inherited from the previous CRT screens. Just so I can be more careful on some other occasion, what range might be considered reasonable as "a few years ago" I wonder?

How about they are all one stop from an interchange on to a National Rail service, with Chesham the odd one out because that National Rail service runs on LUL track there at Chalfont?

The direct route from Hillingdon to the sidings was removed in a track rationalisation just a few years ago. Hillingdon is still available as a destination in the S stock TCMS/CIS though. I imagine it's still available on the Picc trains too.

Slight refinement then, D has two bits of same railway (DLR) coming together, as well as DLR and LUL Jubilee.

Hey, back off a little. I was only pointing out that increasing NL performance wouldn't be a small set of signalling changes, which others might not have inferred. I'm not saying the scheme adopted was necessarily the best solution and I'm well aware of many of its limitations.

Post by t697 on Oct 18, 2023 17:07:14 GMT
Even if the NL trains were made to go faster without TBTC there would have needed to be a lot of resignalling or signalling modifications to provide signal overlaps fit for the higher performance and desired headways wouldn't there? And I seem to recall the TBTC signalling was also eliminating a lot of assets assessed to be life expired wasn't it? One can of course debate the expected life of new signalling assets and its reasonableness...

Finchley Road to Preston Road - Some date to be announced, but later than Easter 2024 seems to be the current info.

Although the screens were renewed only a few years ago, I think the software driving what is shown is the same as drove the CRT screens they replaced.

I recall the Euston Square platform work for the now cancelled eastern entrance was going to involve S stock needing a whole car of doors cut out at that end for a year or more on both platforms while the work was going on. So Circle, H&C and Met users won't be so inconvenienced. The length of walk in the street isn't really that bad but I agree the Euston Square station entrance on the north side isn't very good.

The software tool for 24TS actually seems to be able to give good announcements without the type of problem suggested.

Two different female artistes have already been used. I seem to recall the last set of new recordings rather than just simple edits being done maybe as long ago as about 2015 or 2016, which would have included the MLE stations and the Elizabeth line interchanges, oh and the NLE stations for disruption messaging. Had to wait quite a while for the EL ones to be brought into use! Maybe the next need for new audio will be the LO line names and any other updates needed by then or foreseen for the next few years. There are about 3000 audio files in S stock, so it would be expensive to re-record the full set with one person. If it's ever done, perhaps it would be done using a synthesis based on a specific real human's voice. Same principle as 24TS but for the S stock system synthesised and recorded, rather than synthesised at the moment of use.

Yes, all the necessary audio files for Cassiobridge, Watford Vicarage Road and Watford High Street were also recorded and remain in the current CIS files. Unlike some other redundant items, no instruction has yet been made to remove the Met line Extension (MLE) announcements and trips. There's a maintenance test feature that one can use to play any 'trip' and these have been tested on train that way.
If the MLE were actually to be built, the interchange announcements at Harrow and Moor Park would need amendment.

From the few videos of 1983 stock operations I've seen on YouTube they don't fill the platforms entirely, being six-car trains. Were there any operational difficulties when the 1983 stock shared duties with the longer 1972 stock trains? At that time there wasn't so much concern about end barriers having to meet the end of correctly berthed trains. In any case a similar condition arises at all stations from Great Portland Street to Aldgate where there are platforms used by both S8 (Met) and S7 (Circle and H&C) trains and that is still tolerated!

Papers of the Programmes and Investment Committee meeting for 5 October 2023 have "Expected outputs to March 2026" for CLIP project showing "by March 2024, first CLIP train return to service". Pleasing to see also by then "contract award for seats overhaul". Wasn't it going to be March '23 not so long ago? There must be some lessons to be learnt from CLIP about biting off too much at one go for future projects replacing obsolete equipment on, say, 96TS etc.
