To ask His Majesty's Government what are the expected passenger flow numbers from the Great Western station to be opened at Old Oak Common to London Paddington on the Elizabeth line.

Passenger numbers at Old Oak Common will depend on multiple factors including: what HS2 services are running at that point (including whether Euston has opened as the London terminus); the assumed Great Western Main Line calling pattern; and the assumed Elizabeth Line train frequency.

Following the Network North announcement, detailed modelling and analysis is currently being undertaken for a number of different scenarios, with the aim to provide the best overall service provision for passengers across the rail system as a whole.

This includes timetable development and operational modelling to support a consideration of the optimum Elizabeth Line frequency at Old Oak Common.
