Klang Valley Mass Transit Network


Klang Valley Mass Transit Lines and Stations form the backbone of public transportation across Kuala Lumpur and Selangor, connecting millions of commuters daily. The system integrates Mass Rapid Transit (MRT), Light Rail Transit (LRT), the KL Monorail, and the KTM Komuter trains, linking residential neighbourhoods, business districts, and key attractions throughout the metropolitan area. Over time, this network has evolved into one of Southeast Asia’s most extensive urban rail systems, easing congestion and providing sustainable transport options for the region’s growing population1.

Quick Facts

History of Mass Transit in the Klang Valley

The modern era of urban rail transport in the Klang Valley began with the introduction of the KTM Komuter service in August 1995, operated by Keretapi Tanah Melayu Berhad (KTMB). It was Malaysia’s first electrified commuter rail system, designed to provide frequent services between Kuala Lumpur and surrounding towns such as Klang, Rawang, Seremban and Port Klang2.

Shortly after the Komuter’s debut, the first Light Rail Transit (LRT) line was launched in December 1996 — the STAR LRT (now known as the LRT Ampang Line), followed by the PUTRA LRT (now the LRT Kelana Jaya Line) in 19983. Initially operated by different companies, both lines were later unified under Prasarana Malaysia Berhad in 2004 to streamline management and operations4.

The KL Monorail was introduced in August 2003 to serve the central business and entertainment districts of Kuala Lumpur. Stretching 8.6 kilometres, it connects key areas such as Bukit Bintang, Chow Kit, and KL Sentral5.

The most recent addition to the Klang Valley’s rail network is the Kuala Lumpur Mass Rapid Transit (MRT), a modern, high-capacity metro system developed to complement the existing lines. The MRT Kajang Line (formerly Sungai Buloh–Kajang Line) commenced full operations in July 2017, while the MRT Putrajaya Line opened in phases between 2022 and 20236. A third line, the MRT Circle Line, is currently under construction, planned to complete by 20327.

Integration and Interchanges

The Klang Valley mass transit network is designed for interconnectivity. Major interchange stations — such as KL Sentral, Pasar Seni, Masjid Jamek, and Titiwangsa — allow seamless transfers between MRT, LRT, Monorail and Komuter lines. For example, KL Sentral serves as a hub for the LRT Kelana Jaya Line, KL Monorail, and KTM Komuter services, as well as the KLIA Ekspres and ETS intercity trains8.

As part of an ongoing initiative to improve first- and last-mile connectivity, feeder bus services operated by Rapid KL link many stations to surrounding neighbourhoods and business districts9.
