KTM Komuter

Current network Central Sector KTM Komuter's 287 km (179 mi) network in the Central Sector mainly covers the Klang Valley. It has a total 58 stations. It consists of two cross-city routes, namely the and the , and the airport rail link . Transfers between the two city lines can be made at any of the four stations on the central core: , , and , with the latter 3 providing same-platform or cross-platform interchanges. The is a limited express airport rail link service for passengers headed towards the Sultan Abdul Aziz Shah Airport (Subang Airport). Running between KL Sentral and , it makes one intermediate stop at , before branching off to the airport. The service is the second airport rail link in Malaysia after the Express Rail Link. However, it is temporarily suspended due to low ridership. The routes have been modified over the years. Previously, the Batu Caves-Pulau Sebang line (formerly, Seremban Line) trains would head towards Tanjung Malim while the Tanjung Malim-Port Klang line (formerly, Port Klang Line) trains would head to Batu Caves. Following a successful trial, the routes were swapped. Trains from Seremban began heading towards Batu Caves, while trains from Port Klang headed towards Tanjung Malim. The train service from Seremban was extended permanently to Pulau Sebang/Tampin, hence the current name of the line. The service is subject to overcrowding during rush hours. Several steps were taken to alleviate this. Firstly, the operator introduced a new queuing system, in which the lines are painted on the floor with three colour codes representing each of the train set. Trains were also run in 3+3 formations, although this has been discontinued with the introduction of six-car sets. Northern Sector The KTM Komuter Northern Sector () service initially operated between in Kedah, in Penang and in Perak. This followed the completion of electrification works on that stretch. The route has been modified multiple times since. Today, there are two lines, namely the Padang Besar-Butterworth Line and the Ipoh-Butterworth Line. , and are interchange stations between the two lines. Southern Sector The former KTM Komuter Southern Sector (Malay: KTM Komuter Sektor Selatan) operated as a shuttle service from to following the completion of electrification works on that stretch. The shuttle service would be terminated on 11 July 2016 when it was fully absorbed into the Batu Caves-Pulau Sebang Line. On 14 March 2024, it was announced that the Southern Sector line will be reintroduced as a commuter service from Gemas to Paloh, and Paloh to JB Sentral, once the electrification and double tracking project (EDTP) along that route is completed. On 22 July 2025, KTMB announced plans to introduce Komuter service on the –Pasir Gudang line, which is currently a freight-only route, to serve the higher passenger traffic expected from the upcoming Johor Bahru–Singapore Rapid Transit System. The service is expected to begin in 2026. By January 2026, three sites were proposed for the line's intermediate stations — Taman Daya, Bandar Seri Alam, and Kampung Pasir Putih. == History ==

Central Sector The first double-tracking and electrification project in Malaysia, which costed RM 1.5 billion, began in 1990. The project covered over a 150 km route stretching as far as , and . the completion was delayed as of January 1995, causing the service to not launch on time. As part of KTM's efforts to get the public to "think commuter", KTM offered free rides of the service from 2 to 11 August 1995. The project was finally completed and service started on 12 August 1995 from Kuala Lumpur to Rawang, on what was the original Seremban Line. The commercial run of the service began two days later. KTM Komuter initially had 18 EMU trains and additional 62 trains purchased at RM 180 million. ==Stations==

The Komuter service was largely built from existing lines, with minor alterations (i.e. removal or abandonment of lines and replacement of wooden sleepers with concrete ones). Relevant station platforms were added and heightened to allow easier access to Komuter trains travelling in both directions. Major pre-independence stations, including , , and were retained and upgraded to support the Komuter services. Smaller, wood-based stations and halts along the line that were built at around the same time were either demolished and replaced by modern brick-and-concrete counterparts, or simply abandoned if not preserved (Taiping and Alor Setar stations of the Northern Sector were among the wood-based stations that were preserved and repurposed). The only exception to the rule is the old station, which remained in service years after KTM Komuter's launch, albeit with a replacement platform. The layouts and sizes of the new station buildings, since the launch of the service in 1995, vary by location but are generally divided into two classes: • Railway halts, consisting of a small single-storey structure with only ticket counters (a ticket booth, ticket machines and faregates). The stations are usually placed along straightforward dual tracks. • Medium-sized and single-storey stations, housing both the ticket counters and station offices, and typically stationed along three or more tracks. Such stations are typically intended to support additional responsibilities, such as managing railway signals, controlling railroad switches and handling goods services. The stations themselves are similar in design to the original wood-based stations along the line with slight hints of Western colonial designs (arches, wooden-and-glass windows and wooden doors), but are larger and modernised. Some stations also have parking facilities. The platforms of the 1995 stations are virtually standardised, down to the design of the passenger semicircle-crossed shelters, the use of similarly-styled foot crossings to link all platforms, and the diamonds-based brickwork of the platforms. Depending on the number of patrons through the years, each station has undergone upgrades or expansions that consist of either increasing the number of ticket counters or opening new facilities for use by passengers or railway staff. Taller, wider canopies were erected on the platforms of most stations to replace narrower, original versions in 2006 and 2007. The pace of the upgrades varies by location. During the 2000s, new stations such as the appeared with more modern designs, consisting primarily of high, curved canopies above the entire platforms. Certain new stations along dual tracks are also included with facilities typically reserved for medium-sized stations, such as the . The KL Sentral station, however, is housed under the concrete base of the Stesen Sentral transport hub, and is stark and utilitarian in design. ==Rolling stock==

The original Komuter rolling stock consisted of three versions of three-car Electric multiple units (EMU) added over the course of three years, beginning in 1994. The EMUs were the first in KTM's history. All Komuter EMUs operated in multiple-unit formation, drawing power from an overhead single-phase 25 kV AC 50 Hz catenary supply, with two driving cars and 1 trailer car in between. The EMUs were state-of-the-art, with remote-controlled pneumatic doors, Automatic Train Protection (ATP), train data recorder, wheel-slip control, GTO/IGBT traction electronics and regenerative braking. Up to the point of their introduction, no other KTM motive power used these modern train control systems. Designated by KTM as "Class 8x"s, the EMUs wore yellow, blue and grey livery, a departure from the predominantly grey livery that KTM adopted on other locomotives and passenger coaches at the time. A handful of EMUs included full advertisements on the sides of their cars. The original Komuter fleet consisted of the following models: The Class 8x suffered from more mechanical problems as they aged, especially the Class 81 and Class 82 EMUs, which had poor reliability. The manufacturers of both classes had gone bankrupt since the trains were built, hence spare parts became unavailable. On paper, the number of serviceable units in 2010 stood at 53 out of the original 62, although there are reports of far fewer trains. Ultimately, four Class 81 sets were refurbished, albeit with new motors from Hyundai instead of Jenbacher. All Class 82s were taken out of service. In 2012, the new six-car Class 92 EMUs were introduced, replacing most of the Class 8x series in the central sector. A handful of the Class 8x EMUs remain, either on the KL Sentral-Terminal Skypark Line or on Sentul-Batu Caves shuttle, but many have been reallocated to the Northern Sector. In 2025, Transport Minister Anthony Loke announced that 12 three-car sets will be constructed for the KTM Komuter Northen Sector, having issued the Letter of Acceptance to CRRC Rolling Stock Centre (Malaysia) Sdn Bhd. == Ticketing ==

Beginning 10 September 2018, all services abolished the cash ticketing system, and cashless ticketing methods were made compulsory. Currently, passengers travelling on KTM Komuter may use the following ticketing options: • Mobile ticket (QR code) via KTMB Mobile app • Touch 'n Go card • Ticket Vending Machines (cashless payment via credit/debit cards or E-wallets only) • Ticketing counters at stations • Debit or Credit cards • NFC based mobile payment system (Apple Pay, Google Pay, Samsung Pay) When transferring between lines in a specific sector (except for the KL Sentral-Terminal Skypark Line), passengers need only to purchase a ticket to their destination once, or tap in and tap out once each throughout their journey. ==Ridership==

Ridership statistics published by the Ministry of Transport are for all KTM Komuter services. No separate statistics for the individual lines are published. Statistics before 1999 are also not available. ==Incidents and accidents==

• On the evening of 3 March 2004, a -bound KTM Komuter train on the Seremban Line collided with the rear of another Komuter train facing the same direction, which had been waiting at a signal between and Seremban for five minutes. Forty passengers were injured, but no deaths were reported. The accident was ascribed to the faulty signal light (struck by lightning) that stopped the earlier train, though the driver of the rear-ending train is reported to have run a red light into the section occupied by the rear-ended train. The resulting crash disrupted KTM Komuter services along the line for a day. This is so far the worst accident involving the KTM Komuter service. • On 2 March 2007, a crane fell onto a KTM Komuter train track near station on the Port Klang Line, stranding about 10,000 passengers and cancelling 40 trips. Alternative transport services were provided. • On 25 May 2007, a person was killed after he was hit by a KTM Komuter train while crossing the tracks illegally. Deaths in this manner have occurred along Komuter lines before. • On 27 February 2008, overhead power cables between and stations of the Port Klang Line broke, causing all train services from to terminate at Petaling, unable to move further. • On 22 October 2009, a multipurpose vehicle plunged onto the railway track as it was heading from Kuala Lumpur towards Subang Jaya. Train services were disrupted, and the vehicle was towed away 3 hours after the accident. • On 4 February 2013, A woman in her 50s was run over by a commuter train at station. The victim was said to have been dragged 50m along the track in the incident. • On 15 February 2013 at 23:00, an out-of-service KTM Class 92 SCS 20 train derailed near station while returning to the Sentul depot for maintenance. No one was injured. The train was heavily damaged and was subsequently written off. • On 1 November 2013, a 3-coach KTM Class 83 derailed near station while moving through a track switch. No one was hurt in the incident. The two rear coaches were separated and towed away using a locomotive while the remaining front coach was removed by cranes. • On 18 September 2017, KTM train services suffered a major disruption after an electrical cable snapped at KM361.76 on the tracks between the and stations, causing closure to both of the rail tracks. == Gallery ==
