The Mitsubishi Heavy Industries Crystal Mover C810 is an automated people mover train that serves the Sengkang LRT line and Punggol LRT line in Singapore. The trains have been operating since 18 January 2003, with its first service on the Sengkang East Loop.
The C810 was developed and built by Mitsubishi Heavy Industries in cooperation with Crystal Mover Bodywork, the same company that developed the newer Changi Airport Skytrain. The trains were developed for airport and light rail applications. They are fully automated and driverless, relying on Automatic Train Control (ATC) technology.
Singapore's Light Rail Transit purchased 41 C810s to be used on the Sengkang LRT line and Punggol LRT line. From 2013 to 2015, 16 of the 41 existing trains were modified to enable two-car formations to cope with higher demand for the Sengkang and Punggol LRT lines.
The exterior of the train has a dual-colour colour scheme of dark blue and white. They feature the SBS Transit logo in white. The serial numbers of the trains are marked on the right side of the train at the front and rear. Both the windshield wipers and emergency doors were specially designed for the LRT.
The interior of the Sengkang and Punggol LRT trains feature a red and blue colour scheme. 16 trains that underwent modification have two seats in the front and back converted into perch seats, thus reducing the number of seats to 14 from the usual 18 seats.
As the carriages are closed-end, the train must be stationary and the doors must be open for passengers to move between carriages during 2-car operations.
The configuration of a C810 in revenue service is just the one car. With both the motors and the third rail current collectors, the train cars can be coupled up to 2 cars during service.
The car numbers of the trains range from 01 to 41. Individual cars are assigned a two-digit serial number by the rail operator SBS Transit. A trainset consists of one motor car, e.g. set 01 is car 01. Both digits identify the car number.
On 9 September 2016, SBS Transit as the operator of Sengkang LRT line and Punggol LRT line has announced that 11 of the 41 C810 trains had hairline cracks. [4]
This is barely 2 months after the announcements that the cracks were found in C151A trains which run on both East West MRT line as well as North South MRT line and subsequently C801 trains which run on Bukit Panjang LRT line.
Similar to previous incidents, the joint statement by the SBS Transit and Land Transport Authority said that the cracks were found on the undercarriage of the trains and assure that this does not compromise their ability to bear passenger weight. [4]
SBS Transit has withdrawn affected trains while waiting for the bogie frames found in the undercarriage to be replaced as a precautionary measure. In the report, SBS Transit has said that six of the 11 trains have the issue rectified and resumed their operational duties since while the remaining 5 would be rectified by the middle of next month. [4]
At the same time, the affected bogie frame was sent to Mitsubishi Heavy Industries in Japan for detailed analysis in order to establish the root cause. [4]
The joint statement also said that both LTA and SBS Transit, as well as the manufacturer, will redesign and strengthen the bogie frame structures, which will be applied to all 57 trains including the newer C810A trains. [4] The manufacturer is expected to bear the full cost as well. [4]
On 5 February 2021, the Land Transport Authority announced that it has purchased 17 two-car C810D trains for the Sengkang and Punggol LRT systems, which will replace the 25 existing unmodified one-car C810 trains. [5] In May 2023, the LTA ordered an additional 8 C810D trains, bringing the total number of C810D trains ordered to 25. The additional C810D trains will replace the remaining modified C810 trains.

The North East Line (NEL) is a high-capacity Mass Rapid Transit (MRT) line in Singapore. Operated by SBS Transit, the 20-kilometre (12 mi) line is the MRT's shortest. It runs from HarbourFront station in southern Singapore to Punggol station in the northeast, serving 16 stations via Chinatown, Little India, Serangoon and Hougang. Coloured purple on official maps, it is Singapore's third MRT line and the world's first fully-automated underground driverless heavy rail line.
SBS Transit Ltd is a multi-modal public transport operator in Singapore operating bus and rail services. With a majority of its shares owned by Singaporean multinational transport conglomerate ComfortDelGro Corporation at 75%, it was formerly known as Singapore Bus Services before rebranding to SBS Transit on 1 November 2001.
The Punggol LRT is an automated guideway transit line in Singapore. The line, which initially opened on 29 January 2005, connects the residential districts and suburbs of Punggol to Punggol Town Centre, where it connects with the North East MRT line and the Punggol Bus Interchange. It is the third line of the LRT system in Singapore and like all other LRT lines, it is fully elevated and uses automated trains.
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.
The Light Rail Transit (LRT) is a series of localised automated guideway transit systems acting as feeder services to the heavy rail Mass Rapid Transit, which together forms the core of Singapore's rail transport services. The first LRT line was opened in 1999 and the system has since expanded to three lines, each serving a new town, namely Bukit Panjang LRT line, Sengkang LRT line and Punggol LRT line. Trains on these lines have at least one station interchange link to the MRT.
Rail transport in Singapore mainly consists of a passenger urban rail transit system spanning the entire city-state: a rapid transit system collectively known as the Mass Rapid Transit (MRT) system operated by the two biggest public transport operators SMRT Trains and SBS Transit, as well as several Light Rail Transit (LRT) rubber-tyred automated guideway transit lines also operated by both companies. In addition, local specialised light rail lines are in operation in places such as the Singapore Changi Airport and Sentosa.
The Innovia APM 100 is an automated people mover (APM) rolling stock first developed by Westinghouse, intended mainly for airport connections and light rail in towns. They are operated by Automatic Train Control (ATC), making it fully automatic and driverless.
