The '''Sengkang LRT line''' ('''SKLRT''') is a {{convert|10.7|km|adj=on}} elevated automated guideway transit line in Sengkang, Singapore. The driverless line consists of 14 stations on two loops, with Sengkang station serving as the interchange for both loops and linking to the North East Line on the Mass Rapid Transit system. It is the second Light Rail Transit (LRT) line in Singapore after the Bukit Panjang LRT line, and the first LRT line operated by SBS Transit.

The SKLRT was planned in tandem with the development of the Sengkang estate in the 1990s. Construction of the LRT stations and viaducts was completed in 2001, and the Land Transport Authority transferred operations to SBS Transit in September 2002. The east loop began operations on 18 January 2003, followed by the west loop on 29 January 2005, with Kupang station being the last to open on 27 June 2015.

The line operates using Kyosan Electric's Automated People Mover (APM) fixed block signalling system and Mitsubishi Heavy Industries' Crystal Mover APM cars. The SKLRT initially ran single-car operations until it was upgraded for two-car operations in December 2015 to accommodate increased ridership. Between 2018 and 2022, the SKLRT underwent further renewal works to improve its reliability. A new fleet of 25 two-car APMs is expected to progressively enter service from 2025 until 2028, replacing 25 one-car trains and half of the 16 two-car trains in the existing fleet.

==History== === Planning and construction === The Sengkang estate was first earmarked for development in the Urban Redevelopment Authority's 1991 Concept Plan.{{sfn|Chow|Chia|Zhan|2018|p=52}} At the groundbreaking ceremony of the Bukit Panjang LRT line on 27 September 1996, deputy prime minister Tony Tan announced the government's decision to construct the Sengkang LRT (SKLRT).

The power system of the SKLRT includes a 22 kV AC power intake and distribution network, a 750V DC traction power system, and a 400V AC system for station services. Power is supplied via two 22kV AC feeders from the North East Line to improve reliability and take advantage of the 66kV tariff. The AC supply is distributed through a closed ring network to prevent power disruptions during single outages. At each station, the AC supply is stepped down to 400V AC using service transformers for mechanical and electrical needs. Traction power substations (TPSS) further step down the 22kV AC to power rectifiers that convert it to 750V DC for train operations. Each TPSS is equipped with an inverter system to return excess energy from regenerative braking back to the 22kV distribution network. In 2004, the SKLRT had three TPSS, with one on standby to maintain operations during outages;<ref name="f922">{{cite conference |last1=Thong |first1=T.L.

Fixed platform barriers are intended to prevent commuters falling to the tracks. However, these barriers lack doors and instead have fixed openings for boarding, as the limited space on LRT platforms cannot accommodate the power, communications, and signal control systems required for platform screen doors.<ref name="u587">{{cite web | last=Tan | first=Christopher | title=Platform Barriers at All LRT Stations by 2018 to Prevent Falls | website=The Straits Times | date=21 October 2015 | url=https://www.straitstimes.com/singapore/transport/platform-barriers-at-all-lrt-stations-by-2018-to-prevent-falls | access-date=20 January 2025 | archive-date=1 January 2020 | archive-url=https://web.archive.org/web/20200101182230/https://www.straitstimes.com/singapore/transport/platform-barriers-at-all-lrt-stations-by-2018-to-prevent-falls | url-status=live }}</ref><ref name="b328">{{cite web | last=Kok | first=Yufeng | title=2 Deaths, 1 Injury in Last Decade from Falls on LRT Tracks | website=The Straits Times | date=10 May 2023 | url=https://www.straitstimes.com/singapore/politics/2-deaths-1-injury-in-last-decade-from-falls-on-lrt-tracks | access-date=20 January 2025}}</ref> To enhance safety, SBS Transit has implemented the VAnGuard track intrusion detection system on the SPLRT.<ref name="q325"/> Using video analytics and artificial intelligence, the system monitors footage of tracks and platforms to identify individuals or objects on the tracks.<ref>{{cite web |title=Driving Workplace Safety Forward: SBS Transit Unveils New Innovative Technologies at the Rail Safety Symposium – Annex |url=https://www.sbstransit.com.sg/Uploads/Whats%20New/Press%20Release%20Attachments/2023/Annex%20-%20Driving%20Workplace%20Safety%20Forward-SBS%20Transit%20Unveils%20New%20Innovative%20Technologies%20at%20the%20Rail%20Safety%20Symposium.pdf |publisher=SBS Transit |access-date=20 January 2025}}</ref> When an intrusion is detected, operations control centre staff can press the emergency stop button to halt services on a specific loop.
