The Hyundai Rotem CJ151 is a light metro electric multiple unit (EMU) train operating on the future Jurong Region Line (JRL). Projected to enter service in 2026, these are the JRL’s first generation of rolling stock.
Sixty-two (62) trainsets comprising three cars each were procured, which were wholly designed and manufactured by Hyundai Rotem Company (HRC) in South Korea. HRC will also provide long-term service support to the future JRL operator as necessary, with the first train expected to arrive in Singapore around mid-2024.
Background
Awarded to Korean rolling stock manufacturer firm Hyundai Rotem Company (HRC) in February 2020, Contract J151 (CJ151) for the procurement of rolling stock called for of 62 trainsets of four cars each, at a total value of S$416.5 million. The Contract is likely to include an option for the purchase, delivery and modification of the 3-car trainsets to a 4-car trainset, with the LTA indicating that the JRL infrastructure will be built to support 4-car trains.
This is the first time that HRC is supplying new trains for the Singapore market.
Features
The CJ151 trains for the JRL have carriages that are smaller than that of existing heavy rail lines, allowing for greater manoeuvrability on tracks. Each train car will be 18.6 metres in length and 2.75 metres in width, as compared to 23.6 m by 3.2 m on the Circle Line.
To facilitate easy boarding and alighting, each train car will have three wide doors on each side. At a width of 1.5 metres, these doors are wider than trains on existing MRT lines. Trains will also be designed with spaces for wheelchairs and strollers.
On the technical side, JRL trains will be fitted with an onboard backup power supply that allows the train to be driven to the nearest station should there be a power failure, thus improving accident recovery time. JRL trains are also equipped with advanced condition monitoring and diagnostic systems to detect train faults, with some trains being additionally equipped with an Automated Track Inspection system to monitor the real-time condition of the running rail for defects. This enables the rail operator to adopt a more preventive and predictive maintenance regime.
JRL trains are also designed around various existing suppliers of sub-systems (such as train doors) of other trains in Singapore, which allows for a greater commonality of spare parts, and enables more efficient and responsive maintenance support.

Back to Rolling Stock
With regards to the rail operator of Jurong Region Line, actually I’m into a single rail operator operating all the RTS lines in Singapore, like the Taipei MRT in Taipei, Kaohsiung MRT in Kaohsiung, and Hong Kong MTR in Hong Kong.
For economies of scale, as well as better coordination and optimisation of resources.
They’re hungry thus slashing lower price..The future Cross Island might be Hyundai too
Of course. This is what a responsible government should do: to optimise resources, so that wastage is minimised, and the productivity is maximised.
Can the authorities implement door opening by pressing buttons, just like Europe? If not, they will repeat the same problem with NSEWL trains where all doors are opened regardless of whether it is necessary. The above-ground stations are unlike underground stations, they do not have air conditioning, therefore is hot and humid. Currently, when trains arrived at stations, even those with low traffic or off peak times, all doors are opened automatically. Combined with our hot weather and those under-strength AC units, and some stations having 40/50 seconds stop time despite low volume, it is annoying that aircon escaped and later you can hear the compressors pumping with very slow effect of recovering the cabin temperatures. Bangkok’s BTS have better and more powerful AC units, even though their weather is much hotter!
There are already platform doors blocking off any contact between the passengers on the platform and the train doors, so there is no need for those buttons.
I’m referring to the cabin Air-conditioning. With or without the PSD.
Good! Interested in knowing who is the supplier for Propulsion System and Battery System…
