Light Rapid Transit (LRT) Malaysia is the medium-capacity rail lines in the Klang Valley, Malaysia. The first LRT line was opened in 1996 and the system has since expanded to three lines, which was opened in 1998 and 1999. Along with the MRT, the LRT is constructed and owned by the Prasarana, with operating concessions currently handed to Rapid KL and Rapid Rail. In 2006, the government announced the Sri Petaling Line and Kelana Jaya line extension projects. Unlike the original line, which uses the Fixed-block signaling system, the extension uses the Communications-based train control (CBTC) signaling system.Entrance A of the Tun Razak Exchange MRT station.

The first section of the MRT opened on 16 December 2016, and the network has since grown rapidly in accordance with Malaysia's aim of developing a comprehensive rail network as the backbone of the country's public transportation system. The network consists of three lines – the  MRT Circle Line, looping around Kuala Lumpur, the  MRT Kajang Line and the  MRT Putrajaya Line covering a 20 km radius in the southeast–northwest direction from the city centre – will integrate the current rapid transit system in Kuala Lumpur and serve high-density areas which are currently not serviced by any rapid transit system. About 90 new stations are planned in this "Wheel and Spoke" concept, out of which 26 in the city centre will be underground. Ridership capacity will be 2 million passengers per day.
