Question to the Department for Transport:

To ask His Majesty's Government what steps they are taking to maintain the frequency, reliability and journey times of passenger trains between Cardiff and London during the construction of HS2.

Old Oak Common is a crucial enabler for the Government’s growth mission. During construction there will be periods of full line closures and some periods – generally weekends – when the closure of some lines means fewer services will operate. During full closures, some services from Cardiff to London are expected to divert into London Euston, maintaining direct access into Central London. Government is working with industry to ensure disruption for passengers is kept to a minimum.
