Great Northern Railway (Great Britain)
The Great Northern Railway (GNR) was a British railway company established in 1846. The main line ran from London King's Cross station via Hitchin, Peterborough, and Grantham, to York. There was a loop line from Peterborough to Bawtry (south of Doncaster) via Boston and Lincoln. There were also branch lines to Sheffield and Wakefield. On 1 January 1923 the company became a part of the London and North Eastern Railway. Today, the GNR main line forms part of the East Coast Main Line.
