The new 12-Car non-AC suburban EMU rake with Automatic Door Closure system will shortly undergo Confirmatory Oscillograph Car Run (COCR) trials conducted by the Research Design & Standards Organisation (RDSO).

Presently stationed at Kurla Car Shed of the Central Railway, the rake integrates modern technology and passenger-centric features while retaining the affordability and accessibility of non-AC suburban services.

"This initiative aligns with Indian Railways' commitment to improving commuter safety, especially in high-density suburban sections like Mumbai," CR officials said.

"The introduction of automatic door closure in Non-AC suburban trains represents a transformative step in enhancing commuter safety without compromising capacity. The design also addresses ventilation challenges through innovative engineering solutions like vestibules and high-capacity ventilation systems," the officials added.

These trials are specialised tests carried out to record dynamic parameters such as speed, acceleration, oscillations, and ride quality. These trials help validate the safety, stability, and performance of the rake and track conditions before approval for regular operations.

The rake will also undergo Passenger Convenience & Safety trials to measure various parameters including, effectiveness of braking systems under different load and speed conditions, evaluation of passenger comfort, validation of automatic door closure systems, alarms and interlocking mechanisms to prevent accidents. It also includes testing of seamless integration with signalling for safe train operations.
