Opened in 1932, Tanjong Pagar KTM is a railway terminus owned by Keretapi Tanah Melayu (KTM), the main railway operator in Malaysia. The land on which the station and the KTM railway tracks in Singapore are situated is held by KTM on a 999-year lease.

Following an agreement between Malaysia and Singapore which was reached on 24 May 2010, railway operations into the station will cease by 1 July 2011, after which the building will be conserved and may be integrated with future developments on the site (Wikipedia).
