Keretapi Tanah Melayu Berhad (KTMB) (Jawi: كريتاڤي تانه ملايو برحد) or Malayan Railways Limited is the main rail operator in Peninsular Malaysia. The railway system dates back to the British colonial era, when it was first built to transport tin. Previously known as the Federated Malay States Railways (FMSR) and the Malayan Railway Administration (MRA), Keretapi Tanah Melayu acquired its current name in 1962. The organisation was corporatised in 1992, but remains wholly owned by the Malaysian government. History In 1948, the FMSR was renamed the Malayan Railways. The railways had been devastated by the Japanese invasion of Malaya, and efforts were taken to rebuild the two main lines, but many branch lines were abandoned in the process. The MR began to modernize the equipment with the ordering of diesel locomotives and railcars to replace steam hauled services, and the first diesel locomotive entered service in 1957. The railcars entered service in 1960, initially on short haul services. Rapid services were introduced later, cutting travel times from Singapore to Kuala Lumpur down to six hours, which was competitive at the time. MR and later KTM continued ordering more diesel locomotives through the decades, rendering the old steam locomotives redundant. The last steam locomotive was withdrawn from service in 1974. Malayan Railways also operated an air service from 1954 to 1958, known as Federation Air Service. The service was transferred to Malayan Airways in March 1958. The 1970s saw the closure of many branch lines, such as the Batu Arang branch in 1971 and the historic Taiping to Port Weld branch in 1972. The Port Dickson branch was converted to freight only operation in 1972, although seasonal passenger service did continue for a short while. However, construction did continue for a new line to Subang Airport used to transport fuel, which opened in 1980. Railbuses were introduced in the 1980s for short haul commuter services. They were deployed in the Klang Valley, Kuala Lumpur to Ipoh, Ipoh to Butterworth, Gemas to Mentakab and Kulai to Singapore services. On certain routes such as Kulai to Singapore, the railbuses were faster than conventional trains, and in this instance saved travel time of 15 minutes. They lasted until the introduction of KTM Komuter in 1995, which took over commuter services in the Klang Valley. KTM was corporatised in 1992, with all assets now under the ownership and management of the Railway Assets Corporation (RAC).
