Question to the Department for Transport:

To ask the Secretary of State for Transport, what the cost of alterations to the rail lines to enable Wimbledon trains from Brighton to pass through Blackfriars Station to Bedford and St Pancras was; and if he will make a statement.

The layout of the tracks approaching Blackfriars from the South always allowed for services from Wimbledon and the lines via Herne Hill to access the Thameslink route between Blackfriars and St Pancras. Thus no additional cost has been incurred as a result of this change.
