Question to the Department for Transport:

To ask Her Majesty's Government what plans they have to phase out the use of diesel trains on the lines running in and out of Marylebone station; and what steps they are taking to protect (1) staff, and (2) passengers, at that station from the impact of harmful emissions.

We are currently in negotiations for a new National Rail Contract on the Chiltern route which, if successful, will include plans for improving the environmental impact of stations and trains, including at Marylebone station.

A hybrid trial is currently underway to determine whether this is a feasible option for more environmentally friendly rolling stock on this route. Additionally, we are exploring options for procuring greener rolling stock on the route, and the environmental impact is an important factor in this process.
