The Hyundai Rotem J151 is the first generation electric multiple unit rolling stock to be introduced on the Jurong Region Line of Singapore's Mass Rapid Transit (MRT) system, manufactured by Hyundai Rotem under Contract J151. 62 three-car medium-capacity Hyundai Rotem trainsets (186 cars) will be delivered from 2024 onwards and service will commence when the line opens in 2027.[5]
Tender
The tender for trains under the contract J151 was closed on 13 June 2019 with four bids. The LTA has shortlisted all of them and the results has been released.[6] [7]
Note: Awarded amount to Hyundai Rotem Company as announced by LTA is at SGD 416,499,000.00Design
Every Jurong Region Line train will feature a livery that is mainly teal in color to reflect the line's color on the MRT map. The design features a sleek modern look, with angular LED headlights, similar to that of the C951(A) and R151 trains. The front cab designs are somewhat similar to the Phase III EMUs of the Delhi Metro, also manufactured by Hyundai Rotem.
The Jurong Region Line trains' identification number will take the following format:
Eg. 30011
3 stands for Jurong Region Line
001 train number
1 car number
Features
The J151 train will have the following features that make it better than the other rolling stocks:
- Larger Door Closing Indicator - Provides better visibility on door opening/closing status.
- Wider train doors (1.5 metres, compared to 1.45 metres on other rolling stocks) - Provides better accessibility for passengers during boarding/alighting.
- More space for multi-use - Provides greater convenience for passengers with strollers and foldable bicycles (other rolling stocks only have this kind of accommodation at selected cars, and somemore the provision is only half of what the J151 train will provide).[8]
- Battery-powered emergency propulsion - Enables the train to drive to the nearest station for passenger evacuation in the event of a power outage. This is the first time a MRT rolling stock has this feature. While the earlier rolling stock also has emergency batteries, they are only capable of providing emergency ventilation and lighting for evacuation onto the tracks.[9]
At the same time, the J151 trains will have the following features that are already found in other rolling stocks, namely:
- Condition monitoring and diagnostic systems - Monitors the train health and detect faults for better reliability. Some trains will also have an Automatic Track Inspection (ATI) system, consisting of cameras, lasers and sensors, to detect rail defects in real-time.
- LCD Dynamic Route Map Display - Provides key information such as system map, station arrival and train doors opening side.
- Perch seats, grab poles and hand grips - Provides better comfort for standing passengers.
- LCD Ceiling Display - Provides key information such as station arrival and train doors opening side.
- Ergonomic seats - Provides a more comfortable ride for seating passengers.
In addition, the manufacturer will also tap on existing suppliers of components and systems that are currently used on other rolling stock on the network, which allows for greater commonality between the rolling stock that streamlines maintenance.[10]
Train formation
The coupling configuration of a J151 in revenue service is DM1–T–DM2. D stands for "driver's desk", M for "motor" and T for "trailer".
