The Durham Coast Line is an approximately railway line running between Newcastle and in North East England. Heavy rail passenger services, predominantly operated Northern Trains, and some freight services operate over the whole length of the line; it provides an important diversionary route at times when the East Coast Main Line is closed. Light rail services of the Tyne and Wear Metro's Green Line also operate over the same tracks between a junction just south of Sunderland station and Pelaw Junction (just east of Pelaw Metro station).
