Question to the Department for Transport:

To ask the Secretary of State for Transport, which rail lines are only operated for freight purposes; and what the length in miles of each such line is.

As of 31 March 2022, according to ORR, 777 miles of mainline network in Great Britain are for freight only, with 9,129 miles for passenger and freight traffic. This refers to the mainline railway and does not include privately operated lines, such as terminals, for which we do not hold information.
