History: The line between Grimsby and Boston was built by the East Lincolnshire Railway and opened in 1848, but it was worked from the start by the GNR and was their first line. It was never taken over by the GNR and remained independent until Grouping in 1923 when it became a part of the LNER. It was, however, block signalled by the GNR in the 1880s with this box being built in 1886. It remained operational until 1980. Reference: Michael Vanns, Signal Boxes, Ian Allan, 1997, PPS 99-100.
