73 trainsets consisting of 3 cars each were purchased at a cost of approximately S$570.7 million for passenger service. These trains will be delivered between late 2012 to 2016. They will be stabled at Gali Batu Depot and also on Kim Chuan Depot.
The C951 trains may include several features that were not seen in existing trains. These features have been incorporated into the mock-up of the train at the Land Transport Authority Hampshire Office.
New features include:
- An ergonomic seat profile;
- red reserved seats, which allows for clearer separation between normal and reserved seats;
- perch seats, replacing the two-seaters at the ends of the car;
- a dynamic route map, in addition to dot-matrix displays showing the location of the train, and other information, and;
- hand grips utilising joints instead of straps, providing commuters a steadier grip.
The train will also retain existing features like having two rows of poles and hand grips, and vertical poles which split into three at the center.
The train will have regenerative braking which is usable over a larger range of speeds. This will generate electricity when the train slows, feeding it back to the rail network.
