The rolling stock of the Ampang Line and Sri Petaling 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 on the design for İzmir Metro and Buenos Aires Underground 200 Series.
These trains are disabled-friendly and include safety features like closed-circuit TV, emergency breakable window, emergency ventilation fan, 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 fleet consisted of 90 Adtranz standard-gauge light rail vehicle (LRV) manufactured by Walkers Limited of Australia.
These trains were electric multiple units (EMU), which draw power from the underside of a third rail alongside the track.
All cars in each train were powered.
The trains were manned, with driver cabs occupying the ends of the train.
The trainsets came in two configurations.
The first and most common variation was the six-car trainset, which consisted of three sets of two EMUs (2+2+2) and occupied the maximum platform length of the stations.
Each of the two EMU sets at the front and rear consisted of one driving car and one trailer car, while the two EMUs between were trailer cars.
Each two EMU sets were not connected to other EMU sets in the train.

The second variation was a four-car trainset, a more obscure configuration that consists of only two EMU sets (2+2) of one driving car and one trailer car at both ends.
These were only two-thirds the length and number of cars of the six-car variation.
The 2+2 trainsets were used in full service until the widespread deployment of 2+2+2 trainsets.
Each car had 3 bogies: 2 power bogies and one articulated trailer for the centre bogie.
The end cars, numbered 1101 to 1260, have driver cabs.
Middle cars numbered 2201 to 2230 have a concealed driver control panel, enabling the car to be moved around the depot independently.
The train interiors were simple and basic.
There were no individual seats, only longitudinal bench seating on either side of the train, surfaced in metal, while spaces near the connecting ends of the cars were provided for passengers who use wheelchairs and other assistive devices, with a large amount of floorspace for standing passengers.
The rolling stock, which has remained relatively unchanged since its introduction in 1996, were replaced in stages by the new trains between 2015 and 2016.

The Ampang and Sri Petaling Lines system network fleet consists of the following models:
50 6-car CSR Zhuzhou articulated LRV trainsets, nicknamed as AMY, operated since January 2015.

29 + 1 (out of service) 6-car Adtranz-Walkers LRV trainsets, which were operated from December 1996 until December 2016, have been phased out and replaced by CSR Zhuzhou articulated LRV trainsets.
