The Government is ensuring the railway plays its part in delivering our ambitions to achieve net zero greenhouse gas emissions by 2050 and to reduce air pollution created by transport. We continue to expand the electrified rail network where it delivers passenger and environmental benefits and value for money. This allows removal of diesel trains. For example from this month electric trains can run between London and Cardiff. Network Rail is developing a Traction Decarbonisation Network Strategy to inform Government decisions on the scale and pace of further rail decarbonisation, and the reduced use of diesel trains that this will require.
