Design

Every Jurong Region Line train will feature a livery that is mainly turquoise 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) trains and R151 trains in Singapore and the R-Trains in Hong Kong. The front cab designs are somewhat similar to the Phase III EMUs of the Delhi Metro, also manufactured by Hyundai Rotem.

The trains are also smaller in size compared to those on other MRT lines to enable them to navigate tighter curves in areas constrained by existing developments along the line. [2]

Features

The J151 train will have the following features that make it better than the other rolling stocks:

At the same time, the J151 trains will have the following features that are already found in other rolling stocks, namely:

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. [11]

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".

The train cars are assigned a 5-digit serial number ranging from 3001x to 3062x, where x depends on the carriage type. A complete three-car trainset consists of one trailer (T) and two driving motor (DM) cars coupled together, e.g. set 3001 consists of carriages 30011, 30012, 30013.

The trains are able to be coupled into a 4-car train set if needed to increase train capacity. [2]
