Question to the Department for Transport:

To ask His Majesty's Government, further to the Written Answer by Lord Davies of Gower on 15 December 2023 (HL801), what are the sources of the “in vehicle” and “walk” times quoted; what is their assessment of the breakdown of times by vehicle and walking between Old Oak Common and Euston on HS2, and between Euston and Bond Street on the Underground; and whether they are able to model the journey times from Old Oak Common to Tottenham Court Road.

The estimated ‘in vehicle’ and ‘walk’ times quoted are outputs from the Station Choice Model which forms part of the Planet Framework Model used to assess the impacts of HS2.

The breakdown of in-vehicle time for passengers travelling to Bond Street via HS2 to Euston is as follows: 6 minutes between Old Oak Common and Euston on HS2 and 6.6 minutes on the London Underground. It is not possible to further breakdown the walk time in the journey without commissioning further work.

While journey times to Tottenham Court Road could be modelled, the Department does not currently hold estimates of these journey times developed on a consistent basis and would need to commission these separately.
