This additional batch of trains will increase the capacity of the Bukit Panjang LRT line by 50% by 2014. As of 4 September 2015, all train cars are officially on revenue service.

Overview

To prevent overcrowding on the Bukit Panjang LRT line, 13 new trains were purchased, thus increasing the fleet capacity by 50%. The first car was delivered on 15 June 2014 bearing the number 120. It started service on 19 November 2014 and by 4 September 2015, all 13 train cars were on service. However, in March 2019, 2 train cars numbers 128 & 131 were sent back to New Jersey, USA for retrofitting works of new signalling equipment. These cars returned to Singapore in April 2021. The remaining 11 train cars will have theirs done locally once the retrofitting is completed for the 2 train cars. On 29 July 2023, the 2 retrofitted train cars 128 & 131 have re-entered passenger service. As of November 2024, 6 cars (Cars 122, 128, 129, 130, 131 and 132) have completed the retrofitting of the new CBTC system. 1 car (Car 124) is undergoing the retrofitting of the new CBTC system.

Train formation

The configuration of a C801A 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 120 to 132. Individual cars are assigned a three-digit serial number by the rail operator SMRT Trains. A trainset consists of one motor car, e.g. set 120 is car 120. The first digit is always a 1, while the last two digits identify the car number.

• Bombardier Transportation built sets 120 – 132.
