History

The Ampang Line and Sri Petaling Line were originally known as the STAR LRT (abbreviation for ''Sistem Transit Aliran Ringan'', which translates to Light Rail Transit System), a single train line originating at Sentul Timur station, with two branches to Ampang and Sri Petaling via Chan Sow Lin station. STAR LRT was first conceived in the 1981 Transport Master Plan, when the Malaysian government proposed a network of LRT lines connecting Kuala Lumpur city centre with the surrounding areas. An agreement was signed between the government and STAR in 1992. The original system (27.4 km) consists of 25 stations built in two phases. Phase one (12.4 km) consists of 14 stations ( AmpangSultan Ismail) and a depot near Ampang station. Phase two (15 km) consists of 11 stations (

in 2004 and the line was renamed the Ampang Line and Sri Petaling Line in 2005. The Ampang Line assumed the branch line between Sentul Timur and Ampang stations, whereas Sri Petaling Line assumed the branch line between Sentul Timur and Sri Petaling stations. In 2006, the government announced the Sri Petaling Line extension project. The extension comprises 11 new stations over 17.7 kilometres of elevated track beyond Sri Petaling station. This extended the terminus of the Sri Petaling Line from Sri Petaling to Putra Heights. Unlike the original line, which uses the Fixed-block signalling system, the extension uses the

(CBTC) signalling system. As a result, when the first four stations and the next four stations opened on 31 October 2015 and 31 March 2016, the extension ran as a separate train service between Sri Petaling station and Bandar Puteri station. Re-signalling had to be carried out on the original line before the extension could be combined with the rest of the line.

was awarded a contract on 3 September 2012 to upgrade the signalling system on the original line, and the work was completed in July 2016.


Stations

The Ampang and Sri Petaling Lines run on a common route between Sentul Timur station and Chan Sow Lin station, serving central

and the city centre, effectively making all the stations on this section act as interchanges between both lines. The stations have a dedicated platform for trains travelling north to Sentul Timur, and one for trains travelling to Chan Sow Lin, with trains on the respective lines taking turns to stop at the stations at a given time. From the Chan Sow Lin station, the lines diverge and run separately. The Ampang Line travels to its terminus, Ampang station, serving towns in the Cheras and

alongside the track. All cars in each train were powered. The trains were manned, with driver cabs occupying the ends of the train. The four-car trainset, an initial configuration that consists of only two EMU sets (2+2) of one driving car and one trailer car at both ends were used from the beginning of the operation in 1996. This formation were used in service until the centre trailer cars were added, becoming 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. 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.

Accidents and incidents

There were two major incidents since the opening in 1996.


Sentul Timur buffer overshoot

On 27 October 2006 on 7:11am, a six-coach Adtranz LRT train which came in from Ampang overshot the end of the elevated tracks at the end of the stabling tracks at Sentul Timur station, resulting in the front half of the set 1113 dangling in the air about 25 m above the ground. A lone driver was the only one on board when the incident took place. Only Sentul Timur endured service disruption for 20 minutes that day.


Bukit Jalil train collision

On September 24, 2008 at 6:30pm, two LRT trains collided about 200m from Bukit Jalil station. A carriage of one of the trains involved in the accident hit the rear of the other train, resulting the suspension of the operation on that day. Six passengers were injured in this accident.
