Government support rail electrification as it helps to reduce carbon emission and cut running costs. It is keeping the case for further electrification under review subject to rolling stock considerations, value for money and affordability. However, our priority is tackling the fiscal deficit and Ministers will consider the full range of proposed transport projects in parallel with the spending review process to ascertain what is affordable.
