The Changi Military Railway was a 4-mile long standard gauge line built by the FMSR for the War Department, for the protection of Singapore's new Naval Base at Sembawang. The fortifications for the Naval Base were laid at the entrance to the Old Strait, at Changi, where one 15-inch gun, one 9-inch battery, one 6-inch battery and search lights were installed. The artillery installations were supplied with underground ammunition depots and loaded with armour piercing shells. On the beach, concrete machine emplacements and wire were installed. Airfields in Sembawang, Seletar and Tengah were to provide air cover for the Base. Bagnalls of Stafford supplied an 0-6-0ST, number 2547 of 6/1936, to the War Office department, Changi, Singapore. It had 16" x 22" cylinders and 3' 4" driving wheels. It was last seen derelict in 1947 but its fate is unknown. The railway ran from Fairy Point pier to the battery with a short branch to a depot.
