On 23 July the Government announced the electrification of the Great Western Main Line between London and Swansea, and the line between Liverpool and Manchester via Newton-le-Willows.
This electrification programme radically affects the requirements for rolling stock over the next decade. As a result, the previously planned procurement by the Department for Transport of new diesel multiple units has been superseded. We will publish an updated rolling stock plan, taking account of these changes, in the autumn.
As part of the Intercity Express Programme, the Department is procuring new electric and bi-mode (electric and diesel) Super Express Trains to operate services on the East Coast Main Line and the Great Western Main Line. Bi-mode trains utilise the electric wires where available and continue beyond the wires using the diesel engine. An announcement on the placing of orders for Super Express Trains will be made in due course.
