Question to the Department for Transport:

To ask Her Majesty's Government what are their latest estimates for the cost of the station serving Great Western, Heathrow Express and TfL train services at Old Oak Common; how many station platforms are planned; when development approval will be sought; and whether these costs related to Old Oak Common station are included in the Government’s cost estimate for HS2.

Old Oak Common will contain 14 platforms: 6 subterranean High Speed platforms and 8 conventional rail platforms for services on the Great Western Main Line.

Within the Target Cost for Phase One, the budget allocated by HS2 Ltd for the Old Oak Common station, including contingency for risk, is £1.67bn (2019 prices). A more detailed breakdown of costs cannot be provided as this information is commercially sensitive.

The High Speed Rail (London to West Midlands) Act provides the necessary powers for the station.
