Virtual simulators are multiplatform simulators which can be used on modern devices like computers, smartphones, tablets and even on virtual reality headsets. They provide a high level of immersion through a 3-D environment and provide flexibility in terms of training location. The fault simulation system in the simulators also employs advanced technology through which all possible faults that can occur in the locomotive are fully simulated. The trainee driver can take corrective action based on the standard TSD (troubleshooting directory) for the vehicle and when faults require the driver to go to the machine room, rooftop or under the train, corrective action can be taken through a 3-D virtual screen. These individual systems work in tandem to generate a full simulation of a real environment.
