The Branford Steam Railroad (reporting mark BSRR) is 7.2-mile (11.6 km) standard-gauge industrial railroad that serves the Tilcon Connecticut stone quarry in North Branford, Connecticut, in the United States. It was founded in 1903 by Louis A. Fisk, a businessman from Branford, Connecticut, to transport passengers to a trotting park for horses. Fisk also chartered the Damascus Railroad in 1905 to extend the route of the Branford Steam Railroad to North Branford to serve quarries. The Damascus Railroad's charter was amended in 1907 to allow a further extension to the site of a new quarry adjacent to Totoket Mountain. The Branford Steam Railroad took control of the Damascus Railroad in 1909, and has been the operator since.
