Fleet
The rolling stock of the Kelana Jaya Line, in use since the opening of the line in 1998, consists of a fleet of 35 Mark II Bombardier Advanced Rapid Transit (ART) trains[14] with related equipment and services supplied by the Bombardier Group. The ART trains consist of two-electric multiple units, which serve as either a driving car or trailer car depending on its direction of travel. The trains use linear motors and draw power from a third rail located at the side of the steel rails. The plating in between the running rails is used for accelerating and decelerating the train. The reaction plate is semi-magnetised, which pulls the train along as well as helps it to slow down.
The ART is essentially driverless, automated to travel along lines and stop at designated stations for a limited amount of time. Nevertheless, manual override control panels are provided at each end of the trains for use in an event of an emergency.
Since October 2006, the operator has ordered 35 new 4-car trainsets to be delivered starting from 2008. Due to some delays from the manufacturer, the delivery was delayed to November 2008. After extensive series of testing, the first batch of trains began operation on 30 December 2009.[15]
The rolling stock of the Ampang Line currently consists of a fleet of 50 new trains, better known as AMY, that are deployed to increase the capacity of the line and provide a better service. Each of the new trains is six cars long and provided by CSR Zhuzhou of China, similar to the design for İzmir Metro and Buenos Aires Underground 200 Series. These trains are disabled-friendly and include safety features like closed-circuit TVs, emergency breakable windows, emergency ventilation fans, fire and smoke detection system and supervised automatic train operation system (SATO), and other elements such as interactive destination display inside the train, non-slipping seats, LCD infotainment, walk-through gangways, and a more spacious wheelchair space for the physically challenged. The first trains were put into service on the Sri Petaling-Kinrara BK5 stretch in October 2015, and then until Putra Heights and Sentul Timur in July 2016, and finally the Ampang branch line in December 2016.
The former rolling stock of the Ampang Lines consists of a fleet of 90 standard gauge light rail vehicles manufactured in Australia by Walkers Limited.<[16] The trains consist of electric multiple units, which draw power from the underside of a third rail installed along a side of the line. All cars in each train are fitted with both current collector and motors. The trains are manned, with driver cabs occupying the tips of the trains.
The trains come in two trainset configurations. The first and most common variation is the six-car trainset, which consists of three sets of two EMUs (2+2+2) and uses the maximum platform length of the lines' stations. Each two EMU sets at the front and rear consist of one driving and one non-driving motor car, while the two EMUs between are non-driving motors. There are no gangway connections between the two-car sets. The second variation is a four-car trainset, a more obscure configuration that consists of only two EMU sets (2+2) of one driving car and one non-driving motor at each end, thus with two-thirds the capacity of the more common six-car set. The 2+2 trainsets were once used in full in the service until the massive deployment of 2+2+2 trainsets.
Each car has 3 bogies, 2 powered end bogies and one trailing bogie under the central articulation. The end cars, numbered 1101 to 1260 have driver cabs. The middle car number 2201 to 2230 have concealed driver control panels to enable the car to be moved around the depot independently.
