The Academy is equipped with state of art train sub-systems Trouble Shooting & Maintenance Simulators pertaining to the Rolling Stock for the training of maintenance staff and Train Operators. The academy has eleven independent simulators that help provide maintenance training for different sub-systems of train such as the Brakes, Air Supply, Door System, Auxiliary System, Traction System, Train Air-Conditioning, Vehicle Control Circuit and Train Control Management System (TCMS). The academy is introducing nine more independent simulators for the maintenance training for different sub-systems of train such as the Bogie, PA/PIS, Gangway/Coupler, CI, SIV, UTO, HVAC, Gearbox and Traction Motor. The Trouble Shooting and Maintenance Simulators simulate all the faults that appear in the metro train and are being used to train the maintenance staff for quick and effective diagnosis of faults. These simulators are 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 with animations 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 with audio-visual animations. This e-learning facilitates maintenance staff to know the system working principle and technology used in train before normal operation, circuit simulation, fault troubleshooting and maintenance practice training. 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 maintenance training.
