The Boston, Sleaford and Midland Counties Railway opened a railway line between Grantham and Boston, through Sleaford, England. It opened in two stages, in 1857 and 1859.
Although not a major line, it formed part of a route from industrial cities in the East Midlands to Lincolnshire seaside resorts, and a major seasonal traffic developed in the twentieth century.
The line remains open at the present day.
