As announced on 30 September, Network Rail are working with the Department and Rail North to develop a new plan for electrification of the TransPennine line to focus on delivering key passenger benefits as quickly as possible. In his letter to the Secretary of State, Sir Peter Hendy, the chairman of Network Rail, stated that the planning of this work will be concluded by the end of 2017. The intention is to use the Calder Valley Line as a diversion during the works on the North Transpennine Line via Stalybridge. The details of the calling patterns of the diverted trainsare not yet determined, as the works need to be planned first. The Department and Rail North will work with the new train operators over the next few years to plan the calling patterns. The new train operators will take over from April 2016.
