Design & features
The train's exterior will feature a livery similar to that of newer trains such as the CT251 and C951, with a teal stripe just below the window sill, running the length of the train, against a white background. The design features a sleek modern look, with angular LED headlights, similar to that of the Bombardier Movia C951/C951A and Bombardier Movia CR151 trains. It will feature wider doors at 1.5 metres each, to allow for quicker alighting and boarding, compared to the 1.45 metres on current trains. Every car will include an open area to accommodate wheelchair users and strollers, compared to the single wheelchair allocation in specific cars on current trains.[4]
The trains also include several features to facilitate more efficient maintenance of the rolling stock and tracks, such as advanced condition monitoring sensors and diagnostic systems to detect faults beforehand. In addition, some trains will also have an Automatic Track Inspection (ATI) system, consisting of cameras, lasers and sensors, to detect rail defects in real-time. A first for an MRT rolling stock, the trains have onboard emergency batteries capable of driving the train to the closest station for passenger evacuation in the event of a power outage. While current rolling stock also have emergency batteries, they are only capable of provided emergency ventilation and lighting for evacuation onto the tracks.[5]
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.[6]
