Question to the Department for Transport:
To ask the Secretary of State for Transport, what estimate his Department has made of the proportion of the UK rail fleet that is composed of rolling diesel stock; and what the expected proportion will be in (a) 2025, (b) 2030 and (c) 2035.
Out of a national fleet of over 14,000 vehicles, there were approximately 3,400 passenger vehicles in service at the beginning of July 2020 that formed part of a diesel powered train. Decisions about the necessary pace of removal of diesel trains from the network to decarbonise the railway will be informed by ongoing work led by Network Rail.
