Klang Valley Integrated Transit System
The Klang Valley Integrated Transit System is an integrated transport network that primarily serves the area of Klang Valley and Greater Kuala Lumpur. The system currently consists of 11 fully operating rail lines; two commuter rail lines, five rapid transit lines, one bus rapid transit line and two airport rail links to the Kuala Lumpur International Airport and another one to the Sultan Abdul Aziz Shah Airport.
History
Initially, different competing companies operated the various transit systems and had developed these rail and bus systems separately and at various times.As a result, many of these systems did not integrate well with the others, making transferring from system to system inconvenient for passengers.
Aggravated by Kuala Lumpur's poor pedestrian network, moving from one rail system to another often required a lot of walking, stair-climbing, and escalator-use.
The introduction of the integrated ticket for all rail-based systems, the cards, helped any passenger transfer seamlessly across all stations and lines in the Klang Valley region.
Integration
Since 28 November 2011, the paid areas of shared stations along the Rapid KL system for the,, as well as the from 1 March 2012, have been integrated physically under a common ticketing system, effectively making those stations into interchange stations.This enables commuters to transfer between lines the interchange stations without buying a new ticket each time, provided that they do not exit the paid area. This is currently possible at the,, and stations. With the addition of the latest rapid transit line on 17 July 2017, the, the integrated system has been expanded to, - and stations, and to station with the launching of the.
The Touch 'n Go stored value fare card is accepted as mode of payment on the Rapid Bus system, LRT, MRT, BRT and monorail lines, as well as the KTM Komuter, easing the hassle of buying separate tickets for travelling on different networks. However, the fare integration for the Rapid KL system does not include other rail systems such as KTM Komuter and Express Rail Link.
Rapid Rail, the operator of the LRT, MRT, monorail and BRT lines as well as Rapid Bus, has launched a daily bus ticket which costs as low as RM1, and an integrated transit daily pass which can be used on both its rail and bus services costing RM7.

The KTM Komuter, a commuter rail service, was introduced in 1995 as the first rail transit system to provide local rail services in Kuala Lumpur and the surrounding Klang Valley suburban areas. Light rapid transit lines and monorail line were introduced later on to serve the urban Kuala Lumpur area and its satellite towns. The mass rapid transit lines aims to connect the outskirts of the Klang Valley with the city centre. Malaysia's first bus rapid transit line was introduced to ease pedestrian traffic in Bandar Sunway, a thriving leisure and entertainment township in Subang Jaya. 3 airport rail links connect the city centre with the 3 major airports of the Klang Valley, two to the Kuala Lumpur International Airport and klia2, and one to the Sultan Abdul Aziz Shah Airport in Subang.
Proposed and Future lines
The construction for the second MRT line, the was started in November 2015. The fourth LRT line, the is also under the construction phase.Fleet
