Trouble Shooting and Maintenance Simulators

DMRC has state of the art training facilities for training of maintenance staff in the trouble shooting and maintenance of Metro Trains.  DMRC has setup eight independent simulators for the maintenance training for different sub-systems of train such as the Brakes, Air Supply, Door System, Auxiliary System, Traction System, Train Air-Conditioning and Train Control Management System (TCMS).

The Trouble Shooting and Maintenance Simulators simulate all the faults that appear in the metro train and are being used to train Operation and Rolling Stock maintenance staff in quick and effective diagnosis of faults. These simulators also used to train the staff for replacement of critical components in a 3D virtual environment.

All electrical circuits of the metro trains are completely simulated allowing the trainee to do a “What if” analysis on any part of the vehicle sub-system

E-learning provides a self-paced training of all subsystems for basic and advance understanding of concepts. This E-leaning facilitates maintenance staff to know the system before troubleshooting and maintenance.

Wall charts and other training aids will supplement the simulator in transferring knowledge and skills to the staff. The Hi-tech and state of the art simulators help in improved training effectiveness. This is arguably the first time in India that such state of the art technology is being used for the purpose of maintenance training.
