Why won’t we get 12 carriage trains on the Wimbledon loop and the stations up to and including Elephant & Castle?
There will be extra room in the rush hour on the Wimbledon loop brought in during 2009 when we will be able to run more longer, eight-carriage trains. However, we can’t run 12-carriage trains, it’s just too expensive and in many cases it is not possible to lengthen the platforms. For example, at Tulse Hill there are complex sections of track at each end of the station and a large bridge which cannot be moved.
