C151A Fleet Info


On May 6, 2009, the Land Transport Authority announced that Kawasaki Heavy Industries and CSR Qingdao Sifang had won over Hyundai Rotem, Bombardier Transportation and Mitsubishi Heavy Industries to secure the contract at a cost of S$369 million, despite Hyundai Rotem offering the lowest bid at S$323 million for the order of 22 trainsets.

Trainset numbers

The car numbers of the trains range from x501 to x570, where x depends on the carriage type.

  • The first digit depends upon whether the car is the first, second or third car from the end of the train it is nearer to, where the first car has a 3, the second has a 1 and the third has a 2.
  • The other 3 digits is the train identification number. A full length train of 6 cars have 2 different identification number, one for the first 3 cars, and the same number plus 1, for the other three. The smaller number is always at the front.
    • For example, train 569/570 would consist of 6 cars with serial number 3569, 1569, 2569, 2570, 1570 and 3570 respectively.
  • Depending on the direction of travel, the sequence may be reversed.
