Canada Water platform extension confirmed
TfL has confirmed that five-carriage East London Line trains will start running at the end of next year, with all doors opening at Canada Water, thanks to a platform extension at that station.
Confirming the appointment of the construction contractor, TfL says:
The first of [the five carriage] trains will run on the East London route - Highbury & Islington to New Cross, Crystal Palace, West Croydon and the South London route to Clapham Junction - by December 2014.
Works to extend platforms will take place at the following stations on the East London route: Highbury & Islington, Canonbury, Hoxton, Haggerston, Dalston Junction, Shoreditch, Shadwell, Wapping, Canada Water and Surrey Quays on the east London route, as well as Wandsworth High Street, Clapham High Street and Clapham Junction on the south London route. Work at the first of these stations is expected to begin in autumn.
The short platforms at Canada Water can't currently accommodate five carriages, meaning that without an extension, the front doors would have remained shut. These works mean that work-around won't be necessary.
With thanks to Matt on the South East London transport forum.
