Work on the Calder Valley Line to increase capacity and provide the infrastructure to enable shorter journey times on this busy rail corridor is currently in the final planning stages and will start on the ground in January 2016. Network Rail is currently updating its national electrification strategy. This includes the case for electrifying the Calder Valley line. Network Rail is taking into account the recommendations of the Northern Electrification Task Force - which placed this line in the top tier for consideration. The updated strategy will inform the Government’s next Rail Investment Strategy for the period 2019-2024.
