J151 - A closer look

Screengrab from video by LTA

With the arrival of the first J151 train for the Jurong Region Line (JRL), let's take a look at some of th features of the trains. Several years back, the Land Transport Authority (LTA) ran a poll to decide on interior design choices for the trains. Members of the public were allowed to choose from pre-selected options for design choices pertaining to the block design approach for grab poles at doors, colour combination of seats, draught screen patterns and floor colours. We'll dive into these and a few more facts of the J151 trains after the jump.

Let's begin with some facts of the J151 trains.

Number on order - 62
Initial train length - 3 cars / 56.8m
Eventual train length - 4 cars
Train width - 2.75m
Doors per side of train car - 3 sets
Seats between sets of doors - 8 seats, the longest on the entire rail network / 6.2m

Moving on to design poll and the choices made.

Seat colour combination - Magenta (Driving motor car), Orange (intermediate trailer car), Lime (Driving motor car)
Block design approach for door grab handle - Option B1, only behind the grab pole
Draught screen pattern - Triangles

As part of the design review & development prior to production of the train sets by Hyundai Rotem, the initial triplicated grab poles located through the middle of the train were removed. The removal of these poles will enable easier access for wheelchair passengers and those with prams.

The trains will eventually be handed over to operator Singapore One Rail - a joint venture between local operator SBS Transit and French operator RATP Dev. Interestingly, the colour selected for the JRL also happens to be the corporate colour of RATP Dev, which runs other metro systems in cities such as Paris (France), Cairo (Egypt), Doha (Qatar) and Riyadh (Saudi Arabia).
