Kelana Jaya line

With the incorporation of Projek Usahasama Transit Ringan Automatik Sdn Bhd (PUTRA-LRT), construction began on 15 February 1994, about the same time as construction of the Ampang Line. ^{[citation needed]} The tunnels were constructed by Hazama Corporation and Hyundai Engineering & Construction.^[4] Operations commenced on Section 1 from Subang Depot to Pasar Seni on September 1, 1998. Section 2 from Pasar Seni to Terminal PUTRA (now known as Gombak), which includes Malaysia's first underground railway, commenced operations on June 1, 1998.^[5]

Due to financial difficulties, PUTRA-LRT was wound up by the Kuala Lumpur High Court in April 26, 2002. By September 1, 2002, PUTRA-LRT came under management of Syarikat Prasarana Negara (also known as Prasarana Malaysia) and renamed "Putraline" under the first phase of the restructuring of Kuala Lumpur's public transport system.^{[citation needed]} Prasarana also takes over STAR-LRT and is renamed "Starline". Operational aspects of the two lines are transferred to the new government-owned Rapid KL in November 2004 under the second phase of the restructuring process. ^{[citation needed]} Ownership of their assets remains with Prasarana.^{[citation needed]}

In July 2005, the line was rebranded as Kelana Jaya Line, with all station signage changed by 2006.

On 29 August 2006, Malaysian Deputy Prime Minister Dato Seri Najib Tun Razak announced that the western end would be extended to the suburbs of Subang Jaya (USJ and Putra Heights) to the south-west of Kuala Lumpur. The extension would be part of a RM10 billion plan to expand Kuala Lumpur's public transport network.

The expansion plan would also see the LRT Sri Petaling Line extended to the suburbs of Puchong and the south-west of Kuala Lumpur. The plan also involved the construction of an entirely new line, tentatively called the Kota Damansara–Cheras line, running from Kota Damansara in the western portion of the city, to Cheras in the southeast of Kuala Lumpur.

As of August 2008, Syarikat Prasarana Negara was reportedly running land and engineering studies for the proposed extension.^[6]

In September 2009, Syarikat Prasarana Negara began displaying the alignment of the proposed extensions over a 3-month period for feedback. The Kelana Jaya extension would have 13 new stations over 17 km from Kelana Jaya to Putra Heights. Construction was expected to commence in early 2010.^{[7][8][9][10]}

In November 2010, Prasarana announced that it had awarded RM1.7 billion for first phase of the project. The winners included Trans Resource Corp Bhd for the Kelana Jaya Line extension. UEM Builders Bhd and Intria Bina Sdn Bhd were appointed as subcontractors for the fabrication and supply of segmental box girder jobs for the Kelana Jaya Line.^[11]

Construction works on the Kelana Jaya Line and the Sri Petaling Line extension project were targeted to accelerate at the end of March 2011, with commencement of structural works, subject to approval from state government and local authorities.^[12]

In 2014, completion of the extension was targeted for 2016.^[13] On 14 April 2016, Prasarana Malaysia confirmed in a media release that the Kelana line extension would be fully operating on 30 June 2016.^[14]

The extension begun operation on June 30, 2016, with 13 new stations added to the line beyond the Kelana Jaya terminus, the new terminus is now at Putra Heights, where the line meets with the LRT Sri Petaling Line.^[7]

Location of Kelana Jaya LRT line

The line runs from Putra Heights through Kelana Jaya to Gombak, serving the Subang Jaya and Petaling Jaya regions to the south; southwest and central Kuala Lumpur, and the Kuala Lumpur City Centre; and low-density residential areas further north.^{[citation needed]} At 46.4 km (28.8 mi) in length, it is one of the longest fully automated driverless metro lines in the world.^{[citation needed]}

The stations are given in a north–south direction, consists primarily of elevated stops and a handful of underground and at-grade stations. Of the 37 stations, 31 are elevated, Sri Rampai lies at ground level, and five stops (Masjid Jamek, Dang Wangi, Kampung Baru, KLCC, and Ampang Park) are underground.

The stations, like those of the Ampang and Sri Petaling Lines, are styled in several types of architectural designs. Elevated stations, in most parts, were constructed in four major styles with distinctive roof designs for specific portions of the line. KL Sentral station, added later, features a design more consistent with the Stesen Sentral station building. Underground stations, however, tend to feature unique concourse layout and vestibules, and feature floor-to-ceiling platform screen doors to prevent platform-to-track intrusions. 22 stations (including two terminal stations and the five subway stations) use a single island platform, while 15 others use two side platforms. Stations with island platforms allow easy interchange between north-bound and south-bound trains without requiring one to walk down or up to the concourse level. The island platform at Putra Heights terminal station is shared with the Sri Petaling Line trains bound for Sentul Timur, allowing cross-platform line interchange at the station.

The stations were built to support disabled passengers, with elevators and wheelchair lifts alongside escalators and stairways between the levels. The stations have platform gaps smaller than 5 cm (2.0 in) to allow easy access for the disabled and wheelchair users. They are able to achieve this with:

• Tracks that are non-ballasted, lessening rail and train movements
• Trains that have direct rubber suspension, lessening train body movements
• Trains that do not rapidly run through stations
• Stations that have straight platforms

The stations on the Kelana Jaya Line are the earliest rapid transit stations in the Klang Valley designed to provide a degree of accessibility for handicapped users.^{[citation needed]} In contrast, handicapped-friendly facilities for the Ampang and Sri Petaling Lines were installed beginning in 2012.^{[citation needed]}

The stations have closed-circuit security cameras for security purposes.^{[citation needed]}

The rolling stock, was in used since the opening of the line in 1998 until 2023, consists of 35 Innovia ART 200 trains^[7][15] with related equipment and services supplied by the Bombardier Group and train electronics company Quester Tangent. They consist of two-electric multiple units, which serve as either a driving car or trailer car depending on the direction of travel. They were equipped with Linear Induction Motor (LIM) propulsion technology which allows for operation on tighter curves, with less noise and greatly reduced wheel and track wear. The plating in between the running rails was used for accelerating and decelerating the train; additionally, the reaction plate was semi-magnetised, which pulls the train along and helps it slow down.

The ART was completely automated and operates without drivers, stopping at stations for a limited amount of time. Nevertheless, manual override control panels were provided at each end of the trains for use in an event of an emergency. The technology was essentially identical to that of the Vancouver SkyTrain, which operates in very similar environments.

The interior of the ART, like its Ampang and Sri Petaling Lines' counterparts, consists of plastic seating aligned sideways towards the sides of the train, with one foldable seats for passengers at the end of the cars for wheelchair, and spacing in the middle for standing occupants. Since its launch in 1998, the ART rolling stock has remained relatively unchanged; only more holding straps have been added and the labeling has been modified from Putra-LRT to Rapid KL. Some of the rolling stock has the majority of the seats removed for added passenger capacity during rush hours.

With the fleet being aged, a tender was released by Prasarana in 2023 for the disposal of 4 2-car trains.^[16]

On 23 May 2023, two-car train Number 32 was sent to Megalift, which handled logistics for the train's relocation.^[17][18] Train 32 was repurposed as a prop for disaster management training. It will form part of the simulation site at Pulau Meranti for the Malaysian Search & Rescue Team (SMART) to train on.^[19]

As of now, all unrefurbished 2-car trains are retired and replaced by new trains.

On 13 October 2006, Syarikat Prasarana Negara signed an agreement with Bombardier HARTASUMA Consortium for the purchase of 88 Innovia ART 200 cars (22 train sets of 4-cars), with an option for another 13, for RM1.2 billion.^[20] The 22 train sets, initially targeted to be delivered from August 2008 onwards, would have four cars each, boosting the carrying capacity of the fleet by 1,500 people. On 7 October 2007, Syarikat Prasarana Negara exercised its option to purchase an additional 52 Innovia ART 200 cars (13 train sets of 4-cars) for €71 million. The first trains were expected to enter revenue service in 2010.^[21]

Although the trains were expected to arrive in August 2008, the manufacturer delayed the delivery to November 2008. ^{[citation needed]} Rapid Rail said that the trains will only be usable by September 2009 after having sufficient rolling stocks, power line upgrades, and safety testing.^[22] Transport Minister Datuk Seri Ong Tee Keat said in Parliament that the new trains would begin operations by December 2009.^[23] However, in July 2009, Prime Minister Najib Tun Razak announced that the four-car trains will only be fully operational by the end of 2012.^[24]

On 30 December 2009, 3 of the 35 new four-car trains entered commercial service.^[25] In addition to increased capacity up to 950 passengers per trip, new features included seat belts for wheelchair-bound travelers, door alarm lights for hearing impaired, and more handles for standing commuters.^[26]

In June 2012, several 2-car Innovia ART 200 trains underwent major refurbishment work done by from Hartasuma Consortium.^[27] Known as Mid-Life Refurbishments (MLR), these refurbishments include an updated livery, changes of the LED headlights and interior lights, and interior refurbishments such as newer seat design and the installation of additional infotainment systems. Facilities were also added, such as openable windows during emergencies. The first MLR set, TR08, entered service on 15 October 2014.^[28]

In 2017, another MLR project included two 2-car sets permanently coupled to form a 4-car set, known as the 'married train'. Interiors were similar to the previous MLR sets with added TV panels at each end of the sets, dynamic route map displays and walkable through gangways between the two sets. The first coupled train, TR87 (previously TR22 and TR27), entered service on 29 December 2017, with the remaining undergoing delivery in stages.^[29]

Since the delivery of the new KLAV27 trains, the remaining 2-car trains that are not refurbished will be replaced by the new trains.^[30] As of now, only 20 2-car trains are refurbished (including married trains).

Under the Kuala Lumpur Additional Vehicle programme, the first new generation Bombardier Innovia Metro 300 started service on 29 December 2016.^[31] Each driverless train features a new design for the end caps, a curved sidewall structure, and a larger, more spacious interior. All trains come in a four-car configuration with each car accommodating up to 220 passengers. Low energy consumption is achieved through a combination of lightweight aluminium car shells and a LIM propulsion system. Furthermore, the vehicle's regenerative braking enables the reuse of energy released during braking. The aisles and walk-through gangways are also wider when compared with the previous fleet. In addition, the trainsets are equipped with 16 cameras on board, infotainment LCD screens, dynamic route maps, better air-conditioning and bigger windows. With the new trains, the line could increase its capacity by 20 to 30 percent.^{[32][33][34][35]}

An additional 27 new trainsets are being delivered. As of August 2020, three have arrived with two of them under installation. They were delivered for the first time by air using an Antonov An-124, one of the largest cargo planes in existence. The rest of the fleet are to be delivered by ship.^[36] Since 27 June 2021, two trainsets labelled Sets 92 and 93 were spotted to be in service on the line.^{[note 1][37]} As of 14 September 2023, three trains in addition to the eight introduced previously are in operation.^{[note 2][39]}

Due to recent developments in numerous breakdowns involving the 4-coach ART 200 fleet,^[40][41][42] it was revealed by Rapid KL that mid-life refurbishment is to be done on the 34 trains.^{[note 3]} According to former Transport Minister Wee Ka Siong, faulty or dated equipments included tachometers, electronic units and antennas. The most serious contributor to faults were from tachometers, accounting up to 47%. This refurbishment was expected to cost RM 800 million in May 2022.^[45]

The Kelana Jaya Line fleet consists of the following models:

The old RM10 banknote of the 1996 series featured an image of the 2-car Bombardier Innovia ART 200 Kelana Jaya Line train.

On 24 July 2006, failure of the back-up computer causes the line to stop functioning during the evening rush hour. Passengers are trapped in trains and some force open doors to get out.

On 6 October 2006, a "technical problem" causes a train to stall between Dato Keramat and Damai at 7am, causing a shut-down of the Masjid Jamek — Gombak LRT Station stretch. Normal service is restored by 5pm that day. ^{[citation needed]}

On 12 December 2006, an accident occurs during peak hour as a train was approaching Pasar Seni LRT station. The train stops abruptly as if it hit something. No casualties occur.^{[citation needed]}

On 4 March 2018, a high-voltage power line broke and fell on the roof of the Kelana Jaya station, causing the roof to be blown off. Trains on both routes pass through the station while it is closed for repairs. The Kelana Jaya station reopened a few days later.

On 2 May 2022, a train braked suddenly in the tunnel between Dang Wangi and Kampung Baru while travelling towards Gombak at around 11:20 p.m. The train eventually continued towards KLCC, with passengers being asked to disembark. No injuries were reported.^[49]

In November 2022, a series of service disruptions caused by faulty automatic train control (ATC) device(s) forced trains to move slower and stop longer than usual, especially between Kelana Jaya and KLCC stations.

On 5 November 2022, a fault occurred between KLCC and Ampang Park stations. RapidKL resolved the problem by updating the software of the faulty ATC device, and train service resumed as usual on 6 November 2022. The problem resurfaced again between KLCC and Kelana Jaya stations on the evening of 7 November 2022. Stations between Damai and Lembah Subang were closed at night to resolve the ATC stability issues.^[50] However, the same problem recurred on the evening of 8 November 2022, leading to a 4-day suspension.^[51] Prasarana carried out the repairs, including finding the root cause of the problem.^[52] After the subsequent stability tests under the supervision of technical experts from Thales Group and Land Public Transport Agency, the Ampang Park-Kelana Jaya stretch re-opens on 14 November 2022, two days earlier than expected.^[53]

On 24 May 2021, at 8:45 pm MYT, train number 81 and 40 collided with each other between the KLCC and Kampung Baru LRT stations. Both trains were traveling in opposite directions on the same track and collided head-on. One of the trains was under maintenance and was being driven manually on the wrong track, while the other was automatically driven from KLCC. The cab ends which collided were carriages 181 and 240. A total of 213 people were on board the automated train. Preliminary reports indicated that no fewer than 166 people were injured, 47 of which were serious;^[54] no deaths were reported, but 64 people requiring hospitalization, with 6 in critical condition. The case is under investigation as of 25 May 2021. This is the only and most severe incident involving a collision between two trains to occur along the Kelana Jaya line since it first opened in 1999.^[55]

In 2002, the line carried its 150 millionth passenger, with an average of passengers daily.^[56] Today, it carries over 250,000 passengers per day^[2] and over 350,000 per day during national events.^[57]
