The Mitsubishi Crystal Mover (C810A) is a rubber-tyred automated people mover (APM) train operating on the Sengkang LRT (SKLRT) and Punggol LRT (PGLRT). Entering service in April 2016 on the Sengkang LRT’s East Loop, these were the Sengkang & Punggol LRT Line’s second generation of rolling stock.
Sixteen trainsets were procured, and were manufactured from 2012 to 2016 by Mitsubishi Heavy Industries in Mihara, Japan. They were delivered with the capability of operating in two-car formations.
Awarded to Mitsubishi Heavy Industries, Contract 810A (C810A) for the procurement of rolling stock called for 16 single-car trains to increase the capacity of the Sengkang and Punggol LRT systems by 40%. 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.
The first trains entered revenue service in April 2016 to support two-car train operations along the crowded Sengkang LRT (East Loop), and more were gradually put into service with rollout of two-car operations on the Sengkang West Loop and Punggol East Loop.
The exterior of C810A trains are similar to the older C810 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 vertically arranged (as compared to horizontally arranged in the C810). 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 C810A 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.
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 42 to 57, i.e. Car 42, Car 43 and on to Car 57. All sets were built by Mitsubishi Heavy Industries. The 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 first-generation C810 trains were found to have hairline cracks on the undercarriage of the trains. As a result, LTA and SBS Transit worked with Mitsubishi Heavy Industries to redesign, strengthen and replace the bogie frame structures on all 57 trains (41 older C810 trains and 16 C810A trains), with Mitsubishi bearing the replacement costs. Replacement work is expected to complete in 2020.
