level crossings along the original alignment. Military railways, 1920s-1930s The Admiralty Military Railway was a line that branched off the main line near Woodlands and was built in the 1930s to serve the Naval Shipyard at Sembawang. Three of the locomotives were 0-6-0Ts built by Hunslet in 1929 and numbered SL18-20. In November 1941 they were transferred to the FMSR as the second Class A, later becoming 331 class before being sold to the Port Of Singapore in 1946. In addition to the metre gauge line there was a standard gauge system and two of the locomotives which operated this system were returned to the UK in 1955. One of these, Hawthorn Leslie 3865 of 1936, an 0-4-0ST named "Singapore", has been preserved. 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. Post-war developments, 1950s-1995 By the time the Second World War ended in 1945, the FMSR was still operating six stations along the line: Tanjong Pagar, Tanglin Halt, Bukit Timah, Bukit Panjang, Kranji and Woodlands. In 1946, the FMSR closed Tanglin Halt, Bukit Panjang and Kranji to allow for faster travel between Woodlands and Tanjong Pagar. Meanwhile, FMSR was renamed as Malayan Railways in 1948 after the formation of the Federation of Malaya; in 1962 it was renamed again as Keretapi Tanah Melayu (KTM). In 1953, a proposal was made to convert the existing Malayan Railway line into a double-tracked electrified light rail transit system to resolve the congestion problem; diesel railcars could be used should this not be economic.
