Following full internal self-governance of Singapore in 1959, the new government under the People's Action Party pursued an aggressive industrialisation policy to resolve unemployment problems, one of which included building Jurong Industrial Estate in 1960. Keen on tapping the economic hinterland of Malaya, a freight-only Jurong line was built in 1963 and was opened in 1965. Trains would run west from Bukit Timah under Clementi Road, through Ulu Pandan, under a roundabout at Upper Ayer Rajah Road and Jalan Ahmad Ibrahim and branched out into three lines that penetrated into Jurong Industrial Estate. Despite high expectations of having 2-3 million tons of good moved every year, a shaky merger with Malaysia from 1963 to 1965 led to under-utilisation of the line's potential. The Jurong line eventually closed in the 1990s despite renewed calls from the Automobile Association of Singapore and various members of the public to upgrade the line for passenger service.
