As the S-Stock is to be universal across the whole SSR element of the Underground, it is logical that they will fit all platforms.
If the new trains were not joined by corridor connections, this would mean that running of 8-car trains on the Met would have to stop if all trains were to be the same length - it would be a problem when running on the Edgware Rd - High Street Kensington section!
However, seeing as there will be full-width connections between carriages, will all sets be 8-car and the doors of the last two carriages be locked out of use when the train is in a station with short platforms?
I suppose the Correct Side Door Enable system already takes care of that - only places where there is the special wiring on the sides of the platform will allow the doors to open at these points.
This could actually allow the largest improvement in capacity the SSR network has ever seen! Passengers could spread out into the extra rear carriages.
The only restrictions would be how far along the train passengers are willing to walk to get to an open set of doors, provided that signal positions and junctions are not fouled by the longer trains, and the train is not so full to bursting that people can't get to the open doors further up the train.
(Baker Street Circle & Hammersmith & City platforms could be a problem actually - there is a flat junction not far from the Eastbound end of the platforms)

The District and C&H S stock trains will be 7 cars and Met Line 8 Cars.
There is a Transport & Works order going in for stations like Bayswater that will need excavation to extend the platforms. Some other stations like on the Hammersmith branch will need longer platforms too.
You are right too about the junctions. Baker Street Junction is only a few feet away from the platforms.

no Ben, there will be some 7-cars and some 8-cars. 7 cars for the District + C&H and 8-cars for the Metropolitan railway. They will have to extend the platforms at quite a few stations on the Circle but it will make a big difference. if you want to find out about some of these things that we have already discussed, set a side quite alot of time to read the 'SSR upgrade newsline' thread'  although your idea of having the 8-cars and just making people walk through is quite a novel one EDIT: started to write at the same time, but I have a broken finger so have slower typing! |

I still want to know how a 7-car train built to C stock dimensions is going to fit in Hammersmith station.

Well perhaps the platforms will be extended at both ends - the ticket office demolised and extended that way with buffer stops rather than a sand drag.  |

I'm hopeing LUL suprises all of us and builds a new station at Hammersmith...say at Grove Road...with maybe a connection to the District? Just for stock transfers, of course *hopes with fingers crossed* |

I know ATO is a later add-on, but under ATO is the long sand-drag still necessary (accepting there will be times when they are driven in coded manual)? With refined Moorgate control when in CM, the possibility of an overrun could easily be eliminated (at the expense of very slow arrival speeds under those conditions).

From what my colleagues are saying, it seems that with the requirement for modern train arrestors the space needed in some areas may increase rather than decrease. |

The ticket office may not have to go, if we could have a 're-jig' up the other end. Nothing has been decided yet so I'm not refering to a secret LU plan!

A 're-jig' at the other end is not likely - the presence of the depot constrains the placement of the station throat's layout. Unless Hammersmith Depot is to be decomissioned and the land returned to its owners I'm not quite sure as to what could be done at Hammersmith H&C.

Well the depot wont be needed by Metronet within their fleet plans - but stabling sidings will be.... plus they could go a la White City and put a building on top  |

Unless Hammersmith Depot is to be decomissioned and the land returned to its owners I'm not quite sure as to what could be done at Hammersmith H&C. The long sheds (roads 1 - 5) hold three six car 'C' Stock each, with the exception of 5 which has a store at the bottom and can only take two. These roads will not take three seven car 'S' Stock and so there may be some room left over at the top of the sheds. Just thinking off the top of my head here, but with the top of the sheds gone, you could extend the platforms and move the cross over east. Less radically, you could extend platform one quite easily and with the new train crew facility moved platform three then becomes a better prospect too. I am sure with some work at the end of platform two and the use of selective door opening that platform also becomes more viable. This would then leave the booking hall where it is now. Again, not official plans - just my ramblings!  |
