On 5 February 2021, the Land Transport Authority announced that it has purchased 17 two-car trains for the Sengkang and Punggol LRT systems. The new trains will be delivered progressively from 2024 to 2027. In addition to new trains, the Sengkang Depot will also be expanded to 11.1 ha (27.4 acres) from the existing 3.5 ha (8.6 acres) to ensure that it has capacity and maintenance space for the new trains. The expansion of the depot will also see two new reception tracks being built to shorten the train launching time. To ensure there is enough electricity to support the larger fleet of trains, 3 new power stations will be built, increasing the total number of power stations supporting the system to 8 once completed.[2] In May 2023, the LTA ordered an additional 8 C810D trains, bringing the total number of C810D trains to 25 C810D trains. These 8 two-car trains will replace half of the existing fleet of 16 two-car trains, while the earlier order of 17 two-car trains will replace 25 one-car trains, bringing the total to 33 two-car trains.[3]
On 23 November 2024, the first batch of 25 new C810D trains has arrived in Singapore and will undergo testing and commissioning works at the Sengkang LRT depot before entering passenger service in the third quarter of 2025.
Train formation
The configuration of a C810D in revenue service is M1–M2 with both the motors and the third rail current collectors.
The car numbers of the trains range from 58 to 82. Individual cars are assigned a two-digit serial number by the rail operator SBS Transit. A complete two-car trainset consists of two motor cars (M1–M2).
