The Ampang & Sri Petaling Line (Malay: Laluan Ampang dan Sri Petaling), collectively the Ampang Line (Malay: Laluan Ampang), is a light rapid transit (LRT) line in Klang Valley operated by Rapid Rail, a subsidiary of Prasarana Malaysia.

The line consists of two branch lines and one shared line:

  • Sentul Timur to Chan Sow Lin (shared stations between the two sub-lines)
  • Chan Sow Lin to Ampang
  • Chan Sow Lin to Sri Petaling

The line is one of the components of the Klang Valley Integrated Transit System.

Lines information[edit]


The Ampang Line consists of two routes with a total length of 34.4 kilometres that begin at two different stations to the south and east of the city, meeting at an interchange station, continuing through the city centre and ending at the same station at the north. The Ampang Branch Line begins at Ampang, while the Sri Petaling Branch Line begins at Sri Petaling. Both lines converge at Chan Sow Lin; the merged line leads to the north, terminating at Sentul Timur. The Ampang to Sultan Ismail section was the first phase of the system to open, on 16 December 1995, with the second stretch from Chan Sow Lin to Sri Petaling operational on 11 July 1998, primarily for accessibility to the National Sports Complex during the 1998 Commonwealth Games via the Bukit Jalil station. The section between Sultan Ismail and Sentul Timur opened on 6 December 1998.The passenger seating capacity is 168 seats per train (without wheelchair).

The line between Plaza Rakyat and Sentul Timur is an elevated railway, running along the Gombak River between Bandaraya and Titiwangsa. The Chan Sow Lin-Ampang line is primarily at surface level, using a previously disused railway formation, while the Chan Sow Lin-Plaza Rakyat line and the Sri Petaling-Chan Sow Lin line use a combination of surface-level and elevated tracks. There are no underground sections.

The system includes 29 stations: eleven along the Sentul Timur common line, and seven each along the Ampang Branch Line and the Sri Petaling Branch Line. The service depot and primary train depot is at Ampang. There is a secondary train depot at Sri Petaling.

Unlike previous railway lines in Malaysia, which were built to metre gauge, the Ampang Line was the first railway system in the country to adopt standard gauge. Between Ampang and Plaza Rakyat and between Chan Sow Lin and Salak Selatan, the line uses the trackbed of previously disused lines that were part of the Malayan Railway network (Ampang/Sultan Street branch), closed in the 1960s (between the present Chan Sow Lin station and the present Plaza Rakyat) and the early 1990s (the remaining portion of the line). The Ampang depot stands on the site of the former Ampang railway station.

Ridership on the line has been far below expectations. Built with a capacity of 500,000 passengers per day[2] and a breakeven point of 170,000 passengers per day,[3] in 1998, two years after launch, the line was averaging only 53,000 passengers per day, in part because of fares perceived as too high.[3] In 2002, STAR LRT was taken over by the government-owned Syarikat Prasarana Negara Berhad. By 2003, the ridership had increased to 110,000, still insufficient for profitability.[2]

On 29 August 2006, Deputy Prime Minister Mohd Najib Abdul Razak announced that the southern end of the Sri Petaling Branch Line would be extended from its existing terminus at Sri Petaling station to the suburbs of Puchong and Putra Heights, south-west of Kuala Lumpur. The first phase of the line extension work, a 7.4 km four-station phase from Seri Petaling to Bandar Kinrara (with four new stations: Awan Besar, Muhibbah, Alam Sutera and Kinrara BK5) opened on 31 October 2015. Full service for the remaining stations to Putra Heights is expected to commence in March 2016.

On 29 August 2006, Malaysian Deputy Prime Minister Mohd Najib Abdul Razak announced that the southern end of the Sri Petaling Line, which now ended at Sri Petaling station, would be extended to the suburbs of Puchong and Putra Heights, located to the south-west of Kuala Lumpur. The extension will be part of a 10bil ringgit plan to expand Kuala Lumpur's public transport network.

In September 2009, Syarikat Prasarana Negara began a public viewing for the details of the alignment for the Ampang Line and Kelana Jaya Line at various locations. After a number of amendments and public viewings, the new extension will add 11 new stations and 18.1 km of new track. The Ampang Line Extension starts from Sri Petaling Station and passes through Kinrara, Puchong and ends at the new terminus of Putra Heights where the line will meet the Kelana Jaya Line to provide a suburban interchange.[5] Construction works on the Kelana Jaya Line and the Ampang Line Extension project escalated at the end of March 2011, with commencement of structural works, subject to approval from state government and local authorities.[6] Thales Group were selected to provide SelTrac Communications-Based Train Control (CBTC) for the extension. [7]

The first phase of the line extension work, a 7.4 km four-station phase from Seri Petaling to Bandar Kinrara (with four new stations: Awan Besar, Muhibbah, Alam Sutera and Kinrara BK5) opened on 31 October 2015, while the full service on the remaining stations to Putra Heights is expected to commence in March 2016. The extension project is slated to double the ridership on the Ampang Line to more than 400,000 passengers per day.[5][8]

When the STAR line was launched in 1996, the Bandaraya LRT station became the first STAR station to be designated as an interchange station, with a footbridge connecting to the Bank Negara Komuter station, a KTM Komuter regional rail station, a few hundred metres away. With the completion of the Sri Petaling-Chan Sow Lin line, the Bandar Tasik Selatan station was opened as a more integrated interchange between the STAR line and the KTM Komuter network. The line would later include interconnectivity with Kelana Jaya Line, ERL and KL Monorail services. The system currently has a total of five stations linked to other railway systems.

The Ampang Line is the only rail system in the Kuala Lumpur rail transit network that, though it passes through the city centre, does not stop within or near Kuala Lumpur Sentral. This is because KL Sentral, despite its name, is not in fact in the centre of KL.

Rolling stock[edit]

The rolling stock of the Ampang Line consists of a fleet of 90 Adtranz standard-gauge trains manufactured by Walkers Limited of Australia. These trains are electric multiple units (EMU), which draw power from the underside of a third rail alongside the track. All cars in each train are powered. The trains are manned, with driver cabs occupying the ends of the train.

The trainsets come in two configurations. The first and most common variation is the six-car trainset, which consists of three sets of two EMUs (2+2+2) and occupies the maximum platform length of the stations. Each of the two EMU sets at the front and rear consist of one driving car and one trailer car, while the two EMUs between are trailer cars. Each two EMU sets are not connected to other EMU sets in the train. 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 trailer car at both ends. These are 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 has 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 are simple and basic. There are 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 are provided for passengers who use wheelchairs and other assistive devices. There is a large amount of floorspace for standing passengers. The rolling stock has remained relatively unchanged since its introduction in 1996; new trains will be used on the line from October 2015.

50 new trains will be deployed to increase the capacity of the line and provide a better service. Each of the new trains is six cars long[5][9] and provided by CSR Zhuzhou of China, based on the design for metro trains in Izmir, Turkey.[8] 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.[10][11]

The Ampang Line & Sri Petaling fleet consisted of the following models:

  • 29 + 1 (out of service) 6-car EMU trainsets Adtranz manufactured by Walkers Limited currently in operation since December 1996, to be gradually phased out and replaced by CSR Zhuzhou trainsets.
  • 50 6-car Light Rail Vehicle (LRV) trainsets, or AMY, manufactured by CSR Zhuzhou, eight trainsets of which have been delivered since January 2015, the balance being still under construction.

The system has assumed multiple names throughout its service. Initially known as STAR (Malay: Sistem Transit Aliran Ringan; English: Light Rail Transit System), the STAR LRT or the STAR Line, the system was renamed in 2005 to refer to system's two sub-lines: the Sri Petaling and Ampang Lines. In April 2007, the entire system was renamed the Ampang Line as one common line, with no official names given to the sub-lines.

  • 27 October 2006: A six-coach LRT train which came in from Ampang overshot the end of the elevated tracks at Sentul Timur station, resulting in the front half of the first coach dangling in the air about 25m above the ground.
  • 25 September 2008: Six people injured when a train hits another train near the Bukit Jalil station. It is believed that the first coach suddenly stopped 200 metres from the station before it was rammed by another train on the same track. LRT service was disrupted for the day before resuming the next day.[12]
