The Horncastle Railway was a seven mile long single track branch railway line in Lincolnshire, England, that ran from Woodhall Junction (opened as Kirkstead) on the Lincolnshire Loop Line to Horncastle via one intermediate station, Woodhall Spa.
Originally named the Horncastle and Kirkstead Junction Railway, the company was renamed the Horncastle Railway on 10 July 1854. Authorised in July 1854, the line was the brainchild of three local businessmen who were concerned that the lack of a railway would inhibit the town's development, and who negotiated with the Great Northern Railway that they would construct the line and the GNR would run it.
Due to poor weather conditions it was not until the spring of 1855 that work started, but aided by the flat terrain, and lack of major engineering work the line was completed in five months, opening on 11 August 1855. As further work was required to bring the line up to the required standard the line did not open to traffic until 17 August, with full services running from 26 September.
The line was profitable up to Grouping in 1923, when it became part of the London and North Eastern Railway but suffered after competing bus services took most of its passenger traffic. Despite local opposition the line closed to passengers on 13 September 1954, but remained open for freight until 6 April 1971.
