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 (1) on HS2 to Slough, London Heathrow and Reading, and (2) on inter-city trains west of Reading at peak hours.

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.

Detailed modelling and analysis is ongoing to determine the optimum service pattern under different scenarios, to inform decisions on calling patterns and frequencies at Old Oak Common.
