The Sengkang LRT is a 10.7-kilometre (6.6 mi) automated guideway transit line in Singapore. The line, which initially opened on 18 January 2003, connects the residential districts and suburbs of Sengkang to Sengkang Town Centre, where it connects with the North East MRT line, Sengkang Bus Interchange, Compass One and Compassvale Bus Interchange. It is the second line of the LRT system in Singapore and like all other LRT lines, it is fully elevated and uses automated trains. It is the first LRT line to be operated by SBS Transit.

History

[edit]

Planning for the Sengkang LRT line was underway when the Bukit Panjang LRT was opened by then-Prime Minister Goh Chok Tong on 6 November 1999.[3] Construction began in January 2000 for both the East Loop and West Loop. Meanwhile, the Sengkang LRT line was awarded to Singapore Bus Service (present-day SBS Transit) on 20 May 1999.[4][5]

On 18 January 2003, the East Loop was opened, the first section of the line to do so.[6] The West Loop, with the exception of Farmway, Cheng Lim and Kupang stations, commenced operations on 29 January 2005.[7][8] These three stations then opened on 15 November 2007,[9] 1 January 2013[10] and 27 June 2015, respectively.[11]

Improvements

[edit]

On 31 October 2012, the Land Transport Authority announced that starting from the first quarter of 2016, both the Sengkang and Punggol LRT systems would be upgraded to two-car trains, doubling the passenger capacity. An additional 16 cars were to be ordered, bringing the total fleet size to 57. The induction of longer trains also required modifications to the signalling and communication system.[12]

On 22 December 2015, the line began operating two-car trains, five years after plans to raise the capacity of the increasingly packed light-rail system were announced.[13]

Around the end of 2016, two-car trains started being deployed on both directions of the West Loop during the weekday peak hours, due to the increasing number of commuters living in new HDB flats located near Thanggam, Kupang and Farmway stations. Before this, two-car trains were only deployed towards the direction of Cheng Lim during morning peak hours, and towards the direction of Renjong during evening peak hours.[citation needed]

On 15 December 2017, the Land Transport Authority said there will be limited services on parts of the Sengkang-Punggol LRT (SPLRT) on most Sundays from 14 January 2018 to 25 February that year, to facilitate renewal and improvement works (except 18 February as it is a Chinese New Year holiday). Only one platform will open for service at 5.30am on Sundays. The other platform will open from 7am.[14][15][16] On 22nd of that month, SBS Transit said the arrangement is expected to continue until end April that year.[17][18]

From 27 May to 7 October that year, limited services on Sundays will continue on the Sengkang-Punggol LRT (SPLRT). One platform will open at 5.30am and the other platform will open at 5.30pm.[19][20]

On 5 February 2021, the Land Transport Authority announced that it has purchased 17 two-car trains for the Sengkang and Punggol LRT systems. The new trains will be delivered progressively from 2024 to 2027. In addition to new trains, the Sengkang Depot will also be expanded to 11.1 ha (27.4 acres) from the existing 3.5 ha (8.6 acres) to ensure there is capacity and maintenance space for the new trains. The expansion of the depot will also see two new reception tracks being built to shorten the train launching time. To ensure there is enough electricity to support the larger fleet of trains, 3 new power stations will be built, increasing the total number of power stations supporting the system to 8 once completed.[21]

Infrastructure

[edit]

Rolling stock

[edit]
A Mitsubishi Crystal Mover C810 train on the Sengkang LRT East Loop.
The LRT trains on the Sengkang–Punggol LRT lines are parked at the top level of Sengkang Depot.

The Sengkang and Punggol LRT lines (SPLRT) utilise the Crystal Mover Automated People Mover (APM) rolling stock manufactured by Mitsubishi Heavy Industries.[24] The rubber-tired trains are fully automatic and can accommodate up to 105 passengers per vehicle.[25][26] The SPLRT has an initial fleet of 41 APMs, with 16 more APMs delivered under contract C810A.[27][28] The APMs are configured for single car or two-car operations,[27] with a maximum capacity of 36 trainsets on the network.[29] In February 2022, the LTA ordered another fleet of 17 two-car APMs from Mitsubishi for S$439 million.[30][31] This was followed by another order for eight more two-car trains in May 2023, costing S$87 million.[32][33] The new trains are set to replace the 25 one-car trains and half of the 16 two-car trains, bringing the overall SPLRT fleet to 33 two-car APMs.[32]

The APMs have a top speed of 80 km/h (50 mph), with a maximum operational speed of 70 km/h (43 mph).[25] They are powered by 750V DC third rail located on one side of the guideway.[34] Each vehicle is 11.84 m (38.8 ft) long and 2.69 m (8.8 ft) wide.[25] The exterior has a crystal-like design with a polyhedral nose reflective of its namesake. Mitsubishi describes the curved sides of the APM as a design choice to "soften" the sharpness of its polyhedral shape. The exterior is painted pearl white and indigo blue.[35]

As driverless vehicles, the APMs do not include a driver cabin. The emergency stop button and emergency notice system are located at the right-side corner of the vehicle's front, while line maps and service information are displayed on the left. The interior features white side panels and ceiling, a grey floor, grayish-blue seats, and handrails and grip bars accented in a wine color.[35] The cabins are air-conditioned.[36]

The SPLRT trains are maintained and stabled on the second floor of Sengkang Depot.[34] Located between the Layar and Tongkang LRT stations,[37] the depot also houses the trains of the North East line.[30] Its facilitates include a two-story main building with an operation control center room, automatic vehicle washing facility, maintenance garage, departure inspection track, stabling yard, power receiving and transforming facilities, and a test track.[34] The 3.5-hectare (8.6-acre) site is being expanded to 11.1 hectares (27 acres), which will include two more reception tracks and three traction power substations to expand the depot's stabling and maintenance capacity.[30][38]

Train control

[edit]

The Sengkang LRT line is fully automatic,[26] and is equipped with Kyosan APM fixed block signalling system.[39]. The line's Automatic train control (ATC) is composed of automatic train protection (ATP) which ensure safe operations, automatic train operation (ATO) which controls the automatic operations, and automatic train supervision (ATS) for overall command, monitoring and recording of the system.[25] To reduce equipment mass, the ATP and ATO systems on the train are integrated into one unit, althought for safety reasons, the function and control logic of the AVP and AVO systems remain independent.[40] These subsystems are connected via LAN and managed by a computer-based interlocking (CBI) system that oversees traffic safety of the APM.[41][42]

Incidents

[edit]
  • On 20 April 2015, the East Loop suffered a brief service disruption due to a power fault.[43]
  • On 8 May 2015, more than two weeks after the April 2015 disruption, another service disruption occurred on the West Loop, stranding a number of trains for three hours at 5.00 pm.[44]
  • On 16 February 2018, the first day of Chinese New Year, a train broke down near Sengkang station from the West Loop due to a dislodged power collector shoe at 11.09 am. A rescue train managed to haul the faulty train away and services were resumed approximately two hours later.[45]
  • On 9 June 2024, a signalling fault on the Sengkang LRT and Punggol LRT lines caused services to be suspended from the first trains around 5.45 am until 10.12 am.[46]
