The Sengkang LRT Line 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 and the Sengkang 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.


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. Construction began in January 2000 for both the East Loop and West Loop.

Date Section
18 January 2003 East Loop opened (both directions, throughout the day).
29 January 2005 West Loop (except for Cheng Lim, Farmway and Kupang) opened for uni-directional operation.
15 November 2007 Farmway opened.
4 January 2010 West Loop operated in both directions during weekday peak hours.
1 January 2013 West Loop operated in both directions throughout the day, and Cheng Lim opened.[1]
27 June 2015 Kupang opened.[2]


On 31 October 2012, the Land Transport Authority announced that starting in 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 more cars were to be ordered, bringing the total fleet size to 57. The longer trains also required modifications to the signalling and communication system.[3]

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.[4]

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 LRT 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.

Rolling stock[edit]

Trains operating on the line are Mitsubishi Heavy Industries Crystal Movers C810s and C810As. Trains operate from the Sengkang Depot which provides maintenance and train overhaul facilities for both the Punggol and Sengkang LRT lines.

Train Formation[edit]

The original system consists of single-car C810s. Each unit is 11,200 millimetres (11.2 m) long and can carry up to 105 passengers. 16 original C810s were modified to allow two-car train operation and 16 C810As came with this configuration. This boosted capacity to 204 per trip.

Train Control[edit]

The line is equipped with Kyosan APM fixed block signalling system for Automatic train control (ATC) under Automatic train operation (ATO) GoA 4 (UTO).[5] The subsystems consist of Automatic train protection (ATP) to govern train speed, Automatic Train Supervision (ATS) to track and schedule trains, and a computer-based interlocking (CBI) system that prevents incorrect signal and track points settings.
