Advantages of remote control system: 1. As substations and control posts are unattended (due to remote controls) there is considerable savings due to less manpower. 2. Central control station houses the complete info of the route (supervision of all individual posts is simple) hence coordination is very good. 3. As oral instructions are very less, human error based problems are minimized, otherwise oral instructions given over phone may lead to errors. 4. Correct and rapid supervision is possible. 5. Switching operations are carried out safely, quickly, and economically. 6. Maintenance cost is low.
