This month's board papers contain the first ever direct discussion by TfL of what happened and Shepherd's Bush, and what they plan to do about it:
A new station at Shepherd’s Bush on the West London Line (WLL) has been constructed by Westfield together with Network Rail, prior to TfL taking over responsibility for Overground services. It was hoped that this would be opened in time for the start of London Overground services, launched by the Mayor on the 12 November. However, the north-bound platform has insufficient width, given projected passenger levels. Dialogue has taken place with Westfield and Network Rail with a view to rectifying this situation by moving the platform retaining wall and widening access to the platform. It is hoped to provide an opening date once the project plan has been completed. It is estimated that the work will take 4 months following agreement to provide.That puts the earliest opening possible opening date as mid-Summer.
