The Great Northern and London and North Western Joint Railway was a British railway line, almost entirely within Leicestershire. Authorised by the same Act of Parliament, the Great Northern Railway Leicester Branch was built, branching from the Joint Line; on the same basis the Newark to Bottesford Line was built. The lines opened progressively between 1879 and 1883. The dominant traffic was iron ore, and the agricultural produce of the area served also generated considerable business. The passenger usage was never heavy, although some unusual through services were attempted at first.
