The Grantham and Lincoln railway line was a line in Lincolnshire, built by the Great Northern Railway to shorten the distance between the town of Grantham and city of Lincoln. It had already formed a network in Lincolnshire, but the route from London and points south and west of Grantham was very indirect.
The line opened 1867, and was 18 miles in length, from Honington, near Grantham to Pelham Street Junction in Lincoln. Running through rural terrain, it was never heavily developed, and after nationalisation, through traffic was concentrated on a better alternative route via Newark. All local stations except Leadenham closed in 1962, and the line from Honington to Lincoln closed completely in 1965.
