Diesel Locomotive Works, India is the largest diesel-electric locomotive manufacturer in India. I have learnt about Automatic train control (ATC) used as train protection systems for railways that involves speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger. ATC can also be used with automatic train operation (ATO) and is usually considered to be the safety-critical part of the system.I'm very thankful to all the faculty members of DLW for their sincere devotion and patience.
