The history of rail transport in the Comoros began in about 1907. The only railway to be built in the Comoros was a 600 mm (1 ft 11 5⁄8 in) narrow gauge industrial railway. Its owner was a plantation society, the Société Comores Bambaoa. The railway carried only freight traffic. It is not known when the railway was abandoned.
