Question to the Department for Transport:

To ask His Majesty's Government what levels above track are planned (1) for the HS2 train floor levels at exit doors, (2) for new HS2 station platforms, and (3) at stations already in use by national train services.

At the HS2 exit doors, deployable gap fillers extend from the train to provide step-free access. The deployable gap filler has a nominal height of 1135mm above top of rail. This height can vary between 1115mm and 1135mm depending on vehicle movements and loading condition. New HS2 station platforms are being built at 1115mm above top of rail. At existing stations visited by HS2 trains, the nominal platform height is 915mm above top of rail, but with variability due to local conditions.
