Question to the Department for Transport:

To ask the Secretary of State for Transport, what the average age is of (a) diesel-electric and (b) electric locomotives that will deliver annual rail freight growth targets to 2029-30.

As rail freight operating companies are privately owned and operated, the Department for Transport does not hold information on what the average age is of (a) diesel-electric and (b) electric locomotives in their fleets. We do expect that new bi-mode locomotives currently being introduced by operators and the gradual retirement of older diesel units will lower the average age of freight locomotives on the network.
