The Great Northern Railway opened its main line between Peterborough and
Grantham in 1852. Bourne (then spelt Bourn, until 1872) was a significant market town, and influential people in the town saw that a railway connection was important to its continued prosperity.
Stamford already had a branch line: the Stamford and Essendine Railway had opened in October 1856. An army general, a clergyman and some tradespeople in the town put together a proposal which went to Parliament as a bill. The Bourn and Essendine Railway was incorporated by the '''''' (
20 & 21 Vict. c. cxii) on 12 August 1857 with powers to construct a railway from Bourne to the main line station at Essendine. Authorised share capital was £48,000. There were thoughts that this line and the Stamford and Essendine Railway might together form part of a long-distance railway between the Midlands and the East Coast, but this never developed. Moreover, it had been considered to run through trains between Stamford and
Spalding, so that the Bourne line was to cross all of GNR tracks at Essendine, so as to use the Stamford and Essendine Railway platform, on the down side of the main line. The GNR forbade that idea; an alternative put forward by the Bourne directors was to enter Essendine from the south to the S&ER platform, but that would still need to cross all the GNR lines, and it was also ruled out. ==Opening==
