The Mitsubishi Crystal Mover (C810) is a rubber-tyred automated people mover (APM) train operating on the Sengkang LRT (SKLRT) and Punggol LRT (PGLRT). Entering service in June 2003 on the Sengkang LRT’s East Loop, these were the Sengkang & Punggol LRT Line’s first generation of rolling stock.

Fourty-one trainsets were procured, and were manufactured from 2000 to 2003 by Mitsubishi Heavy Industries in Mihara, Japan.

Several units have been modified to be capable of operating in double car formations.


Background

Awarded to Mitsubishi Heavy Industries, Contract 810 (C810) for the procurement of rolling stock called for 41 single-car trains ahead of the opening of the Sengkang and Punggol LRT systems. The driverless Light Rail Transit (LRT) extended the reach of the MRT network into the housing estates, running on its dedicated grade-separated guideway. Trains are rubber-tyred for minimized operating noise within built-up areas.

The trains were built as part of Mitsubishi’s Crystal Mover family of APM trains. They are guided by two side-mounted guide rails and draw power from a 750V DC third rail. These trains are also fully automated (ATO GoA 4) and do not require an attendant on board.


History

The first trains entered revenue service on 18 January 2003 with the opening of the Sengkang LRT (East Loop), and more were gradually put into service with the opening of the Sengkang West Loop, Punggol East Loop and Punggol West Loop.

Between 2013 and 2015, 16 C810 trains were modified to be capable of two-car operations. New signalling equipment were installed in signalling boxes at each end of the modified cars, resulting in the removal of four seats in total. Two-car operations began in January 2016 on the Sengkang LRT, and December 2016 for the Punggol LRT.


Current Design

The exterior of C810 trains are similar to the newer C810A trains, being dark blue with white at the sides, conveying a modern look that complements the new housing estates of Sengkang and Punggol. Apart from the fleet number, the only exterior difference is the headlights, which are horizontally arranged (as compared to vertically arranged in the C810A). Like the Bukit Panjang LRT trains, smart glass (variable opacity glass) was used for the side windows, but are not activated as tracks are not built in very close proximity to residential apartments.

All C810 trains have four wide-opening doors, two on each side. The interior features longitudinal seating in a purple and dark blue color scheme. At the ends of every car, an equipment housing offers a flat platform for additional seating. Trains were also fitted with two Travel Information Displays, which are LED text displays located near the ceiling.

Emergency Exits are located at both ends of every train, with a ramp that can be deployed in an emergency. Within the cabin, Intercom Units and Emergency Next Station Stop buttons enable passengers to speak with staff or stop the train at the next station in an emergency.


Train Formation

Trains can be formed of either one car, or two cars coupled together. Every car is identified by a two digit number on the exterior ranging from 01 to 41, i.e. Car 01, Car 02 and on to Car 41. All sets were built by Mitsubishi Heavy Industries. Trains with underlined car numbers indicate that these cars are able to be operated in two-car formations.


Accidents & Incidents

In September 2016, SBS Transit disclosed that 11 C810 trains were found to have hairline cracks on the undercarriage of the trains, but assured that this did not compromise the trains’ ability to bear passenger weight. The 11 trains had their bogie frames replaced as a precautionary measure. LTA and SBS Transit worked with Mitsubishi Heavy Industries to redesign, strengthen and replace the bogie frame structures on all 57 trains (41 C810 trains and 16 newer C810A trains), with Mitsubishi bearing the replacement costs.
