How Malaysia built one of the world's longest driverless metro lines
In short: The Kelana Jaya Line is a marvel of automation, spanning 46.4 km of track through the Klang Valley. From its origins as the PUTRA-LRT to its current status as a ruby-colored, fully automated transit system, this rail network represents a massive feat of engineering and urban restructuring.
The Kelana Jaya Line serves as a vital component of the Klang Valley Integrated Transit System in Malaysia. Spanning 46.4 km (28.8 mi), the line features 37 stations, most of which are elevated. While 31 stations sit on elevated guideways, five—including KLCC and Masjid Jamek—are located underground. The line is notable for being one of the longest fully automated, driverless metro lines globally, utilizing technology similar to the Vancouver SkyTrain.
The system's history is marked by significant restructuring. Work started on 15 February 1994, with the initial stretch from Pasar Seni to Subang Depot opening on 1 September 1998. The firm, initially called PUTRA-LRT, underwent liquidation via the Kuala Lumpur High Court on 26 April 2002 following fiscal struggles. Following a restructuring process, it came under the management of Prasarana Malaysia and was renamed 'Putraline' before eventually becoming the Kelana Jaya Line in July 2005.
The rolling stock has evolved through various phases. From 1998 to 2023, the fleet utilized 35 Innovia ART 200 trains, which employed Linear Induction Motor (LIM) propulsion technology. This technology allows for operation on tighter curves with reduced noise and track wear. To meet rising demand, the fleet was expanded with four-car train sets, and some older two-car units underwent 'Mid-Life Refurbishments' (MLR) to update interiors and add infotainment systems. By November 2023, all un-refurbished two-car trains had been withdrawn from service.
Accessibility is a core design feature of the line. As early Klang Valley rapid transit hubs built for disabled passengers, these stations include lifts, wheelchair ramps, and platform gaps under 5 cm (2.0 in). To improve passenger stability and safety, the system employs direct rubber suspension on trains and non-ballasted tracks.
