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 1,151-kilometre line is busier than the East Coast railway line because the West Coast railway line handles a variety of passenger train services such as the KTM ETS services, the KTM Intercity services, the International Express, the KTM Komuter in the Klang Valley and Greater Penang, and freight trains. Of this total length, 759 km is double-tracked and electrified.
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.
The West Coast railway line was developed in stretches on June 1, 1885, with the opening of the Taiping–Port Weld Line, and 1932 when the line opened up to Tanjung Pagar, thus spanning the entire west coast of Peninsular Malaysia from Padang Besar on the Malaysia–Thai border to Singapore. The line began with the construction of branches linking coastal ports with inland tin mining areas before they were gradually linked up by the main truck line running through the interior of the West Coast states of Peninsular Malaysia.
The latest new lines to be built were the branch lines to West Port, North Port, Tanjung Pelepas, Pasir Gudang and the North Butterworth Container Terminal. The trunk line had also seen sections becoming disused, abandoned or even removed, with the latest being the closure and subsequent removal of the southernmost stretch of track between the Woodlands Train Checkpoint and Tanjong Pagar in 2011.
The West Coast railway line is served by a variety of train services:[1][2][3]
KTM Intercity
KTM ETS
KTM KomuterAfter many years of announcements about the intention to upgrade the final stretch of single track of the West Coast Line, the Government began the public display exercise for the Gemas–Johor Bahru electrification and double-tracking project on 27 October 2015. The public display exercise, required for all development of new railways under Section 84 of Malaysia's Land Public Transport Act 2010, ran until 27 January 2016. Chinese company China Railway Construction Company (CRCC) has been awarded to build the Gemas–Johor Bahru electrification and double-tracking project.
The length of the line to be electrified and double-tracked is 197 km between Chainage 563.040 at Gemas to Chainage 754.180 at Johor Bahru. The project includes the construction of 11 stations at Segamat, Genuang, Labis, Bekok, Paloh, Kluang, Mengkibol, Rengam, Layang-Layang, Kulai and Kempas Baru, and 3 future stations at Tenang, Chamek and Senai. The upgraded line is supposed to cater for at least 22 services daily involving KTM ETS, KTM Intercity and shuttle train services. Electrification for the stretch will have the same specifications as that of the Seremban-Gemas stretch, name at 25 kV AC 50 Hz single phase and supplied via an overhead catenary. Train operations for this stretch will be integrated with the Train Control Centres at KL Sentral and Gemas. The design speed for the tracks is 160 km/h.
Construction began in 2016 and is expected to be completed by April 2025.[4][5][6]
The project was implemented by Keretapi Tanah Melayu began in 2016 and phase 1 is expected to be completed by 2021.[7] The project entails the rehabilitation of 42 km of tracks between Rawang and Salak Selatan as well as Sentul and Simpang Batu. This will focus on enhancing 16 stations along these routes and upgrade the existing signalling and electrification system.[8] This will be reduced to just seven-and-a-half minutes once the KVDT is completed.[9]
The 42km rehabilitation under Phase I, which are:
Phase II is from Simpang Bangsar - Pelabuhan Klang and Salak Selatan - Seremban.
The West Coast main trunk line stretches from Padang Besar on the Malaysia–Thailand border to Woodlands Train Checkpoint in Singapore.
The main trunk line is double-tracked and electrified from Padang Besar to Gemas. From Gemas to the Woodlands Train Checkpoint, the line is single-tracked and not electrified. Loops at stations allow trains to pass. Double tracking and electrification works are currently being carried out.
The West Coast railway line connects with the State Railway of Thailand at Padang Besar, while the East Coast line branches off at Gemas.
The West Coast railway line includes several branch lines from the main trunk line, namely:
The Bukit Mertajam Junction to Butterworth, Batu Junction to Batu Caves, Port Klang Junction to Port Klang station, as well as the branch line to Terminal Skypark is double tracked and electrified.
The line from Port Klang to Westport and its shipping terminals, as well as the branch lines between Skudai Junction and the Port of Tanjung Pelepas and the Kempas Baru and Pasir Gudang are single lines and not electrified.
There are also branch lines where the tracks exist but are not used for any service or closed are:
None of these disused branch lines are double tracked nor electrified.
