Question to the Department for Transport:

To ask His Majesty's Government what estimate they have made of the cost of constructing the Great Western station at Old Oak Common with (1) four platform faces to serve the Elizabeth line and other suburban services, and (2) four platforms to serve the Great Western inter-city services to Reading and beyond; and whether they will place in the Library of the House a copy of the outline track and platform layout as presently drafted.

As noted in the last report to Parliament, HS2 cost estimates are currently being revised in light of the scope changes arising from the Network North announcement.

Within the Target Cost for Phase One, the budget allocated by HS2 Ltd for Old Oak Common station, including contingency for risk, is £1.67bn (2019 prices). As Old Oak Common is being designed and delivered as a single, integrated station this budget includes the costs for delivering both the HS2 and conventional rail elements.

A copy of the outline track and platform layout as presently drafted will be made available to place in the Library of the House.  Please see the Key Plan attached which was submitted with the Old Oak Common Station Schedule 17 application.
