The West Coast railway line runs from Padang Besar railway station close to the Malaysia–Thailand border in Perlis (where it connects with the State Railway of Thailand) to Woodlands Train Checkpoint in Singapore. It is called the West Coast railway line because it serves the West Coast states of Peninsular Malaysia. The major stations on the line include KL Sentral in Kuala Lumpur, Butterworth in Butterworth, Penang and JB Sentral in the south in Johor Bahru.
