Construction of the LRT stations and viaducts was completed in 2001, and the LTA transferred operations to SBS Transit in September 2002.

[14] In December that year, subcontractor BRR Holdings withdrew from the LRT project and handed over its responsibilities to SembCorp Engineers and Constructors.

[15] On 1 September 2002, the LTA transferred operations of the SKLRT to SBS Transit, which conducted extensive test runs and trials on the line.

[16] In December 2002, transport minister Yeo Cheow Tong said the opening of the SKLRT would be delayed due to modifications required for the communication and radio systems.

[25] At the time, 90% of Sengkang residents lived along the east loop, while the west remained largely undeveloped.

Although the east loop was scheduled to open at 2 pm that day, SBS Transit began operations 30 minutes earlier to accommodate the queue of the 100 waiting commuters.

[27] With the exception of the Farmway, Cheng Lim and Kupang stations, the west loop commenced operations on 29 January 2005.

[18] Farmway station opened on 15 November 2007, to serve the Anchorvale Community Club and the Sengkang Sports Complex.

[21] Full-day bidirectional services on the west loop began on 1 January 2013 with the opening of Cheng Lim station.

[38] The official inauguration of two-car operations on the SKLRT was held on 5 January 2016, with Senior Minister of State for Transport Ng Chee Meng and other Sengkang Members of Parliament in attendance.

[40] The works included replacing the power rail and its assemblies, along with conducting maintenance on the signalling switch machines and cables.

[41] Unidirectional services remained in operation on Sunday mornings from 4 March to 29 April due to the extension of maintenance works on the SPLRT.

[56][57] The Sengkang LRT (SKLRT) is fully elevated automated guideway transit line,[1][a] with a route length of 10.7 kilometres (6.6 miles).

[64] On the east loop, the line heads north from Sengkang station before curving eastward and running along the medians of Compassvale Street and Rivervale Drive.

[65] It crosses Sungei Punggol again between Layar and Tongkang stations, with reception tracks connecting the line to Sengkang Depot.

Mitsubishi describes the curved sides of the APM as a design choice to "soften" the sharpness of its polyhedral shape.

The interior features white side panels and ceiling, a grey floor, grayish-blue seats, and handrails and grip bars accented in a wine color.

[98] Located between the Layar and Tongkang LRT stations,[67] the depot also houses the trains of the North East line.

[56][57] The Sengkang LRT line is fully automatic,[58] and is equipped with Kyosan APM fixed block signalling system.

[104] These subsystems are connected via LAN and managed by a computer-based interlocking (CBI) system that oversees traffic safety of the APM.

Power is supplied via two 22kV AC feeders from the North East line to improve reliability and take advantage of the 66kV tariff.

Each TPSS is equipped with an inverter system to return excess energy from regenerative braking back to the 22kV distribution network.

Emergency stop buttons on both sides of the station platform, when activated, cuts off traction power supply and halts incoming trains.

[100] Fixed platform barriers installed by Chee Yam Contractor are intended to prevent commuters falling to the tracks.

[111][112] To enhance safety, SBS Transit has implemented the VAnGuard track intrusion detection system on the SPLRT.

[114] When an intrusion is detected, operations control centre staff can press the emergency stop button to halt services along on a specific loop.

In addition to track intrusions, the system can spot unattended items on station platforms, allowing staff to provide assistance or undertake security precautions.
