Question to the Department for Transport:

To ask His Majesty's Government what alternatives they evaluated when seeking to reduce the cost of the HS2 connection between Old Oak Common and Euston.

No other alternatives to reduce the cost of the connection between Old Oak Common and Euston were identified at the time of the Government's decision to proceed with the Euston tunnel. The existing tunnelling plans are the most cost-effective approach, as Old Oak Common station's construction has been set up for this purpose.

If this decision had not been made at this time, there would have been likely cost and schedule impacts to the delivery of Old Oak Common station, and potentially to the wider HS2 programme.
