The Kawasaki Heavy Industries & CRRC Qingdao Sifang CT251, alternatively the T251, is an electric multiple unit (EMU) train operating on the future Thomson-East Coast Line (TEL). Entering service in 2020, these were the Thomson-East Coast Line’s first generation of rolling stock.

Ninety-one trainsets comprising four cars each were procured, manufactured from 2015 onwards by Kawasaki Heavy Industries and CRRC Sifang in Qingdao, China. They will be the first trains in Singapore to feature ten passenger doors per carriage (five on each side).

These trains will be entering revenue service in 2020, with the opening the Thomson-East Coast Line Stage 1.


Awarded to Japanese-Chinese consortium Kawasaki Heavy Industries and CSR Qingdao Sifang (now CRRC Qingdao Sifang) in May 2014, Contract T251 (CT251) for the procurement of rolling stock called for of 91 trainsets of four cars each, at a total value of S$749.8 million. They beat Alstom, Hyundai Rotem, Bombardier/CSR Changchun, CAF and CSR Zhuzhou/Siemens for the lowest cost offered.

The first of these trains were delivered in May 2018, ahead of the Thomson-East Coast Line opening. They will also serve on the Singapore-Johor Bahru Rapid Transit Link. These trains will be equipped with the Alstom Urbalis 400 CBTC signalling system. All 91 trains are expected to be delivered by 2022.


Current Design

All CT251 trains are comprised of four cars with open gangway connections between all cars. Each car has five doors on each side, instead of four on other MRT trains, to facilitate quicker and smoother boarding and alighting. The interior features longitudinal seating, with tip-up seats for additional standing space. Perch seats will also be included at the ends of train carriages, similar to C951 trains on the Downtown Line.

After the first trainset was delivered, it was announced that about 60 of the fleet of 91 four-car trains will also have tip-up seats, which will offer more standing space for commuters during rush hours. There will be 10 rows of tip-up seats per train, making up 25 per cent of the seat bays.

Two of the CT251 trains will be fitted with the automatic track inspection system, comprising cameras, lasers and sensors which will help to detect defects on the tracks, such as rail cracks, missing track-rail fasteners or even foreign objects.

Train Formation

Every car is identified by a five-digit number ranging from 2001x to 2091x, where the first digit is always 2, and the last digit x is carriage identifier.  Trainsets are identified by their first four digits, i.e. Set 2001, Set 2002 and on to Set 2091.

As such, a sample Set 2005 will contain the carriage numbers 20051-20052-20053-20054. Depending on the direction of travel, the sequence may be reversed.

Stage 1 Operations

9 trains will be used to facilitate the operation of the Thomson-East Coast Line Stage 1 from Woodlands North to Woodlands South.
