Central Railway (CR) will introduce its first ever 12-car non air-conditioned EMU rake with automatic door closure shortly after it undergoes oscillation trials (COCR trials).
In a statement on Friday, CR said that the new rake will shortly undergo Confirmatory Oscillograph Car Run (COCR) trials conducted by the Research Design & Standards Organisation (RDSO).
These trials are specialized tests carried out to record dynamic parameters such as speed, acceleration, oscillations, and ride quality. They 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 and safety trials to measure various parameters including, effectiveness of braking systems under different load and speed conditions. Also evaluated will be 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. The rake will be introduced in passenger service after successful completion of these trials and appropriate corrections to deficiencies, if any.
CR’s first 12-car non-AC EMU “Medha” rake manufactured by Integral Coach Factory equipped with Automatic Door Closure system, is presently stabled at CR’s Kurla Car Shed.
