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 January 18, 2003, with its first service on the Sengkang East Loop.[1]
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. Currently, sixteen of the forty-one existing trains are undergoing modifications to enable two-car formations to cope with higher demand for the Sengkang and Punggol LRT lines.
Train design
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. For the 16 trains currently undergoing modification, two seats at the front and back will be changed into perch seats, thus reducing the number of seats to 14 from the usual 18 seats.
During two car operations, passengers cannot cross between cars as there is no gangway connecting the cars. The only way is to alight from one car and board the other.

Operational Issues
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 has suffered from the hairline cracks. [2]
This is barely 2 months after the announcements that the cracks were found in C151A trains which runs on both East West MRT Line as well as North South MRT Line and subsequently C801 trains which runs 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 assures that this does not compromise their ability to bear passenger weight.[2]
SBS Transit has withdrawn affected trains while waiting for the bogie frames found in the undercarriage to be replaced as a precautionary measure.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 the six of the 11 trains have the issue rectified and resumed their operational duties since while the remaining 5 would be rectified by middle of next month.[2]
At the same time, the affected bogie frame was sent to Mitsubishi Heavy Industries in Japan for a detailed analysis in order to establish the root cause. [2]
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.[2] The manufacturer is expected to borne the full cost as well.[2]
