The scheduled speed of a train is______

• A. Equal to maximum speed
• B. Always less than the average speed
• C. Equal to average speed
• D. Always greater than the average speed

Answer: (B)

Average speed:- The distance covered between two stops divided by the actual time of the run is known as average speed.
Average speed = (Distance between stops)/(Actual time of run)
Schedule speed:- It is defined as the ratio of distance covered between two stops and the total time of run including the time of the stop.
Schedule speed = (Distance between stops) /(Actual time of run + Stop time)
This shows that schedule speed is always smaller than the average speed. The difference is large in the case of urban and suburban services and is negligibly small in the case of main-line service.
