Railways: Freight
The question
To ask the Secretary of State for Transport, whether her Department has made an assessment of the potential impact of (a) discontinuous electrification and (b) battery locomotives on (i) the decarbonisation of rail freight and (ii) increasing the use of rail freight.
Answered by Simon Lightwood
The department will consider all options, including battery locomotives and discontinuous electrification, when deciding on the best solution for decarbonising freight. Currently, it is unclear what role batteries will play in freight in the short term due to range and weight considerations; however, the technology is constantly improving. The department will continue to monitor developments in battery technology, although it is expected that most decarbonisation in rail freight will come from full electrification and fuel changes. Discontinuous electrification could also play a role decarbonising freight on lines which have lower volumes of freight traffic. Additionally, electric traction has advantages of more pulling power and speed compared to diesel traction and therefore could aid rail freight growth as well as contributing to decarbonisation.
