Manchester Sheffield and Lincolnshire Railway (MSLR)
Formed in 1847 by the amalgamation of the Sheffield, Ashton-under-Lyne and Manchester Railway with two proposed lines - the Sheffield and Lincolnshire Junction Railway and the Great Grimsby and Sheffield Junction Railway. In 1897, the Company changed its name to the Great Central Railway. At the same time the headquarters of the Railway was moved from Manchester to London (Marylebone).
