Features
editEach train car will have 10 doors per car (5 on each side), condition monitoring and diagnostic systems for early detection of potential equipment faults. Some trains will also be equipped with an Automated Track Inspection system to monitor the condition of the running rail and OCR in real time. Between train cars, the gangway width is at 1.6 metres (5 ft 3 in).[4] Unlike most of the MRT lines in Singapore, these trains will draw power from a 1,500 V DC overhead conductor rail.[2]
Train formation
editThe coupling configuration of a CR151 in revenue service is DT–Mp–Mi+Mi–Mp–DT.
