Railway electrification in Malaysia

Railway electrification in Malaysia is a relatively recent development of rail transport in Malaysia. Malaysia's first railway dates back to 1885. The first electrified railway service though (KTM Komuter), only began on 3 August 1995.

"Railway electrification" in Malaysia mainly refers to the electrication of Keretapi Tanah Melayu's (KTM) West Coast railway line from Padang Besar to Johor Bahru. In doing so, any single-track rail used for passenger service is to be replaced with double tracks. Level crossings on the line are also to be eliminated, ultimately making majority of the line grade separated. As of 12 December 2025, the main West Coast Line from Padang Besar-JB Sentral (with the exception of the short JB Sentral-Woodlands portion) as well as several branch routes have been double tracked and electrified. Two electric train services operate on the stretch: the KTM Komuter and the KTM ETS. Former diesel-hauled KTM Intercity services along the line were phased out and replaced with the Komuter and ETS services.

Rapid transit systems in Malaysia are relatively new, the first of which was the LRT Ampang Line (then known as the STAR LRT), beginning operations 16 December 1996. They are designed and built fully electrified and grade separated from service launch.
