KTM West Coast railway line

The KTM West Coast railway line is a main railway line in Malaysia. It runs from Padang Besar close to the Malaysia–Thailand border in Perlis (where it connects with the State Railway of Thailand) to the Woodlands Train Checkpoint in Singapore, running near parallel to the west coast and serving the west coast states of Peninsular Malaysia. The line is owned and used entirely by Keretapi Tanah Melayu (KTM). Past Padang Besar, the line continues on to become the Thai Southern Line, which continues up towards Hat Yai and Bangkok.

The 1,151-kilometre line is busier than its east coast counterpart, the East Coast railway line since it is double-tracked and electrified for most of its route and has more services. The line handles a variety of passenger train services such as KTM ETS services, KTM Intercity services, State Railway of Thailand International Express services, KTM Komuter services within the Klang Valley and the George Town Conurbation, and freight trains. The entire line that is used for passenger services, except the Singapore section, is fully double-tracked and electrified.

Major stations on the line include KL Sentral, Padang Besar, Butterworth, Ipoh, Gemas, Johor Bahru Sentral, and the Woodlands Train Checkpoint in Singapore.
