S stock delivery & introduction - discussion

I suspect it's simply a case of something with sufficient brake force that was available.

I would blame the Signaller, except they're on holiday.

Indeed, it happens a lot. I've seen quite a few different variations over the last 18 months, and if you go back through my Twitter there's a few photos from the other end of the station.

In this instance it is often down to how slow the TCMS system is on the S stock, particularly when livening up. Even when pressing all the correct digits, not all my register, and it's easy to miss that out when you're busy doing everything else that is required of a train operator.



And a very nice holiday it is too.

21029 back in service following ATC modification at Derby. 21035 not noted as returned as yet but 21001 has been to Derby and back and is now ATC modified. 21005 believed to be at Derby possibly along with 21105 and / or 21109.

That seems a logical outcome assuming you want to simplify maintenance regimes. As there is no Croxley link then presumably the original compliment of S8 trains will now be sufficient to meet service needs on the Met.

Removing the extra section from the non standard S7+1s just means the S7 fleet has a spare train which will presumably be identical to all the other S7s.

The follow on question is of course what happens to the two spare sections. I doubt Derby will want to store them indefinitely. So where would they be best stored - please do not suggest Booths!

I suspect they will eventually return to LUL for safekeeping somewhere so they could provide a substitute section to cover for defects in other units, or sadly even a source of spare parts.

I guess the best place for them is one of the S7 depots. Has any of the S7 depots got room to park them long term - presumably at the buffer end of a never used non-electrified siding if there are any still left?

There is the siding at Northwood where the A stock left from, again not especially secure, but I don't think it's electrified.
There is the north end of the shunting neck at Loughton - but good luck getting S stock there in one piece.
South Harrow sidings probably have space now the 83 stock are gone - but they were heavily graffitied while there so probably not the ideal spot.

South Harrow is now in regular use as a stabling point.

I cant imagine any outside sidings being suitable because of security, there is no real need for them to be stored on LUL or bombardier property, other sites are available for rent.

I understand one S Stock car will be going into the ERU compound in Acton Works.

Dan

S8 21105 ATC modified and back in service....followed a few days after by 21035

21099/100 has also now been ATC modified and is back in service on the Met

Seems the S stock are finally getting their CIS systems updated for some of the recent network changes. At Liverpool Street unit 21359/60 included London Overground and TfL Rail on both the PIDs and DVA. It was noticeably different, in a similar way to how changes have been noticeable in the post on Northern and Jubilee stock.

I don't know how long the change has been live, nor what other units have been updated.

CIS = customer information system
PID = passenger information display
DVA = digital voice announcer

I think it was mid-November when I realized Wembley Park announcements now included Wembley Arena aswell the stadium.
