  • After completion of the above, functionality of various subsystems such as Vehicle Control Circuit, TCMS Controls & Interfaces with different sub systems, shore supply, High Voltage, Propulsion fine tuning with Brake system, Auxiliary Power Supply, Brakes & Pneumatics, Door System, Air Conditioning, Lighting, Passenger Announcement & Passenger Information System (PA-PIS) etc. shall be undertaken to verify each subsystem individually & with integrated train testing within depot.
  • The above activities may take one month & once connectivity to the main line is achieved; train field trials will also start.
  • With the arrival of the second train set in March combined integrated testing of the train with Signaling will start in parallel.
