I've seen on here someone say that in one of the tunnels on a metro in the US (Boston I think), there is a tunnel with a continuous platform all along the tunnel - the train just stops at various places along the platform but it's perfectly possible to just walk. I think it's one of the Chicago subway tunnels (i.e. not the Loop) |

I think it's one of the Chicago subway tunnels (i.e. not the Loop) Yes - Chicago - both the State and Dearborn Street subways under the Loop [1] have continuous island platforms about 6 blocks [2] long, with three stops/stations each. [1] In its of the central downtown area, rather than the surrounding L or cablecar loop from which it took its name. [2] In Chicago, 8 blocks to the mile. |

If these trains get any longer they'll be stopping at two stations at once. "The next stations are Bond Street and Tottenham Court Road. Passengers for Bond Street, please move to the rear five coaches. Passengers for Tottenham Court Road, please move to the forward five coaches." Never mind about interchanges being so long that you might as well alight and walk at surface, how about platforms being so long that you might as well get off at the previous stop? At some of the stations they will, in effect, be stopping at two stations at once, as the exits at either end of the Crossrail platforms will lead to different Underground stations. Farringdon will have exits at Farringdon and Barbican, whilst Liverpool Street will have exits to both Liverpool Street and Moorgate. |

That's not actually bad; it'll just be a bit like Châtelet – Les Halles RER: Châtelet Metro at one end and Les Halles Metro at the other.

That's already true of City Thameslink. If you're at the front of a southbound train and want to get to Holborn Viaduct it's quicker to get off at Farringdon than City TL, despite the latter station having an entrance on HV itself. [At some of the stations they will, in effect, be stopping at two stations at once, as the exits at either end of the Crossrail platforms will lead to different Underground stations. Like Waterloo East or Paddington main line stations, or indeed the Northern Line platforms at Bank. |

An S Stock derivative wouldn't be a bad idea for Crossrail - although I'd suggest redesigned for 90/100mph for the long sections Between Maidenhead and Reading.

I wondered why this wasn't done for the new SSL and LO replacements. With appropriate width doors and acceleration (which AIUI is already pretty great) either Desiros or Electrostars could do the job well.

LO uses Electrostars; at tendering Desiros were concidered too. Crossrail will, no doubt, consider the current Bombardier and Siemens products which are better in every way than those supplied in the last 10 years. S stock needed shorter cars, more doors, lower floors. By the time those changes were made it became a different train. However Electrostar experts would recognise lots of components |

However Electrostar experts would recognise lots of components True, and even with all those changes it is still based on the Bombardier Movia platform, just heavily adapted to fit the SSL operation. Desiros and Electrostars would never have fitted in SSL tunnels. |

I also highly doubt that the Electrostar or Desiro platforms would be able to provide the high frequency of stops without compromising line speed. Further, they lack proper M doors. |
