A small local railway company built a branch line from Firsby junction to Spilsby, which it opened on 1 May 1868. The branch was just over long and connected Spilsby to the King's Cross, London to Cleethorpes main line. The only other railway station on the branch line was Halton Holegate Halt. Necessary parliamentary permission was obtained by an Act in July 1865 which incorporated The Spilsby & Firsby Railway Company with an authorised capital of £20,000 and loans of £8,333 for the construction of the four-mile-long single-track branch.
