Sengkang LRT (Grey Line) guide
The Sengkang LRT is a driverless light rail line that carries residents between their housing estates and Sengkang station, where they can change to the North East Line for trips further afield. It is shown in grey on official maps. Its stations use two code prefixes: SE for the East Loop and SW for the West Loop. The line has no conventional end points. Both loops begin and finish at Sengkang station, so on the Sengkang LRT map you will see two rings joined at a single hub rather than a straight line with two termini.
The line serves the Sengkang new town in the north east of Singapore. The East Loop covers the Compassvale and Rivervale side of the estate, and the West Loop reaches Anchorvale and Fernvale, crossing Sungei Punggol twice. SBS Transit operates the line. There are 13 open loop stations, five on the East Loop and eight on the West Loop, plus the shared interchange at Sengkang. The whole route runs on an elevated viaduct of 10.7 kilometres, mostly along the middle of main roads.
Sengkang LRT map: route and where it goes
Every journey on the line passes through Sengkang station. The East Loop leaves Sengkang heading north, then bends east along Compassvale Street and Rivervale Drive. In line order its stations are SE1 Compassvale, SE2 Rumbia, SE3 Bakau, SE4 Kangkar and SE5 Ranggung. After Rumbia the track swings south down Rivervale Drive, turns west onto Sengkang East Avenue and then runs north to rejoin Sengkang station. Trains run in both directions, so riders can choose whichever side of the loop gets them home faster.
The West Loop heads west from Sengkang towards SW1 Cheng Lim, then follows Anchorvale Street and Fernvale Street through SW2 Farmway, which serves Anchorvale Community Club and the flats around it. Between Farmway and SW3 Kupang the line crosses Sungei Punggol. Beyond Kupang it turns south along Fernvale Road to SW4 Thanggam, which has a bridge leading to Jalan Kayu by way of Lorong Samak, and on to SW5 Fernvale. The track then runs east along Sengkang West Avenue to SW6 Layar, crosses Sungei Punggol a second time, and continues through SW7 Tongkang and SW8 Renjong before turning north back into Sengkang station. Sengkang Depot sits beside the line between Layar and Tongkang.
Each loop carries services in both directions, giving four routes in total, and all four share the platforms at Sengkang. Stations sit about 300 metres apart on average, and each is placed so that homes within roughly 400 metres can walk to it. That close spacing is why the Sengkang LRT map looks so dense compared with an MRT line map. A short spur also links the track to the Punggol LRT across the Tampines Expressway, although this connection does not appear as a passenger route.

History
The government announced the Sengkang LRT in September 1996, and planned it alongside the new Sengkang estate, which had been set aside for development in the 1991 Concept Plan. The stations and viaducts were finished in 2001, and SBS Transit took over operations in September 2002 to carry out testing. Because money was tight after the 1997 financial crisis and early ridership forecasts were low, the line first ran single cars, although it had been designed for two. The East Loop opened on 18 January 2003, when most Sengkang residents lived on that side of the town. The West Loop followed on 29 January 2005, but without Farmway, Cheng Lim and Kupang, and at first its trains ran in one direction only, following the peak flow of passengers.
The West Loop filled out gradually as new flats were completed. Farmway opened on 15 November 2007, bidirectional service began during weekday peaks on 4 January 2010, and full day service in both directions started on 1 January 2013 when Cheng Lim opened. Kupang was the last station to open, on 27 June 2015. Two-car trains entered service on 22 December 2015, and the line went through a programme of renewal works from 2018 to 2022 covering the power rail, signalling and viaducts. The LRT platforms at Sengkang station were enlarged, with the refurbished platforms in use from the end of September 2024. A new fleet of two-car trains started running on the Sengkang LRT in January 2026. To connect new reception tracks to the depot, the West Loop ran on its outer loop only from 19 April 2026, with the inner loop returning on 4 October 2026.
Tips for riding the line
- Read the platform colours. On station signs and passenger information displays, yellow marks the East Loop and red marks the West Loop, even though the line is grey on the Sengkang LRT map.
- Find the right stopping point at Sengkang. Four routes share the LRT platforms, and markings on the floor show where each one stops, so check which loop and direction you need before you queue.
- Pick the shorter way round. Both loops run in both directions. Count the stops each way on the Sengkang LRT map; for a station near the far side of a loop, the two directions can differ noticeably.
- Use Sengkang for the city. To travel beyond the estate, ride the LRT to Sengkang and change to the North East Line there.
- Heading to Jalan Kayu? Get off at Thanggam on the West Loop and cross the bridge via Lorong Samak.
