New tube for London stock

What's going on with the Cl.31 and guard's van to the top right..??

The Track Recorder can and does run to Harrow & Wealdstone. The most recent version of that same publication (2018, I believe internal only) corroborates this.

I'm looking forward to seeing what the new trains will be like and what design they go along with. I hope they use the design from the 2014 concept video. It had that 'classic' LU design but more modern. Will the new Piccadilly line trains have luggage space for people going to/from Heathrow?

Looks like a small site for a depot! Maybe a few sidings, but 60 trains? Perhaps there is more space by the Hayes line, or else up in north-west again? The previous consultation to Lewisham only proposed storing 9 trains at terminus within long overrun tunnels. The last consultation proposed sub-surface stabling at Wearside, a proposed line construction site, perhaps like White City Central line. It's a triangular site with the point to the south; best use would have the shunting neck at the Hayes end of the site, so unlikely to be used without access to the Hayes line.

But these 60 are in addition to known requirements, which includes 40 for the Bakerloo

The original plan for 250 trains provided 100 for the Piccadilly and Central lines and 40 for the Bakerloo. Someone must have thought a Hayes extension will make the Bakerloo a full length line, also deserving 100 new trains. These are obviously rough numbers, but the former lines will receive around 100 trains each. The Piccadilly order is for 94 trains for 30tph under new signalling, but could extend to 109 trains for 36tph. I believe the Central line plan is similar in size. The Bakerloo will have up to 100 trains rather than around 100 trains, since the largest fleet I can calculate is some 90 trains.

The current Bakerloo was promised around 40 trains, and the previous consultation for a line to Lewisham said only 9 more trains, so around 50 in total for 27tph. The last consultation gave no train numbers to Hayes, but I estimate 60 for 27tph, and eventually 70 for 30tph, which is the highest frequency mentioned. If 40 can stable on the existing line, that requires 30 more stabled on the extension. If they ever consider 33tph or even 36tph, that may require some running to Watford to provide sufficient reversing capacity, which gave me 90 trains. I presume Stonebridge Park could be modified to maintain the new fleet, given the much reduced maintenance requirements of modern trains.

Wearside Road council site looks to me suitable to hold about 17 full length roads entered from the Hayes end, with two becoming the through roads, and a central reversing road for short workings. Earlier consultations mentioned reversing at Catford Bridge, but not recently, and I wonder if these sidings might be used instead. (Some distance from Lewisham station, but then so is Westbourne Park from Paddington Deep Level!) The current Network Rail connections to the Hayes branch might be retained for engineering trains, and could stable another 6 or 8 trains. That totals a maximum 23 trains, leaving another 7 to stay elsewhere. Is West Wickham former goods yard a possibility?

I think by full length line, what is meant is that the bakerloo line lacks a proper opposite side (in this case south east) to its north west counterpart in harrow, not that it isnt already isn't a full length line. Every other deep level line runs from one side to the other, even if it only stretches as far as zone 3 on one of those sides (bar the W&C). I too have also felt the bakerloo was only 3/4 of a full line and terminated too short on the southern side!

I know the Victoria line doesn't really stretch anywhere far on either side, but thats got an entirely different purpose in that its supposed to be get from one side of zone 1/2 to the other side as quickly as possible, as opposed to having a more commuter line purpose from more further afield.

A Bakerloo line from Watford Junction (or Harrow) to Hayes/Lewisham, now thats a proper full length line!

The recording car of the TRV (so the one 73TS car) is actually certified for Network Rail running I believe. At least going by the information sticker on the end of the recording car. Also one of the reasons its formed with Buckeye couplers and train/main line hoses on the ends.

Perhaps that is what the '+' refers to!

RW819 near camera is 1986 Procor built rail wagon with buckeye coupler 20 tonnes capacity, one of 26 such in the LU Engineer's fleet according to my 1997 edition of Brian Hardy's "LU Rolling Stock" book. So query 1980 open day? Note selection of line diagrams within car! Thanks for photos.

Siemens are contracted to follow the 2014 concept design, or explain why not! We saw updated concept images at the end of 2019, but I can't find them now! (They were in the January 2020 Underground News.) The colour scheme now uses blue grab rails and seating, which looks a lot brighter. They said the suggested 1938 style colour scheme did not meet RVAR requirements for colour contrast, if I recall correctly. The new Picc and Bakerloo trains will be inter-changable, unlike the later planned Central & W&C builds. Luggage racks were part of the prototype 1973TS refurbishment, but considered a waste of space except on Heathrow runs, so general purpose open space is preferred. 

Yes, there was a lot to be desired in terms of how they came to the final design of the 1992 stock.

Note the video says "air cooled" not "air conditioned"

D Stock didn’t have air conditioning, only one C Stock car 6513 was trial fitted.
