Keretapi Tanah Melayu Berhad (KTMB) (Jawi: كريتاڤي تانه ملايو برحد‎) or Malayan Railway Limited, colloquially referred to simply as KTM, 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.

The Port Dickson branch was converted to freight-only operation in 1972, although seasonal passenger service did continue for a short while.

[5] 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.

Proposals were made to electrify the West Coast line, which started with the Klang Valley area.

Electric trains made their debut on 3 August 1995 with KTM Komuter, with services from Port Klang to Sentul and Rawang to Seremban.

The completion of such electrification projects from Padang Besar to Gemas to date has allowed the commencement of electrified intercity services in the form of ETS.

As the projects were completed in stages, the KTM Komuter and ETS services were expanded over the years to take advantage of the upgraded lines.

The remainder of the West Coast main line from Gemas Station to Johor Bahru Sentral Station is still in the process of being double-tracked and electrified under the Gemas - Johor Bahru Electrified Double Track Project.

Although the line will remain single-tracked, rehabilitation works are underway to replace the worn track and many stations are also being upgraded.
