EEE :: Electric Traction
- If the specific energy consumption for suburban services is 50 to 75 watts hours per tonne km, which of the following could be a representative figure for energy consumption on main line service
- The specific energy consumption for suburban services is usually
- Speed of locomotive is controlled by
- A schedule speed of 45 km, per hour is required between two stops 1.5 km apart. The duration of stop is 20 seconds. The acceleration is 2.4 km phps and retardation is 3.2 km phps. For a simplified trapezoidal curve the maximum speed over the mil will be
- When the speed of the train is estimated taking into account the time of stop at a station in addition to the actual running time between stops, is known as
- The coefficient of adhesion is highest when
- Method of speed control used on 25 kV, 50 Hz single phase traction is
- For supply on 25 kV, 50 Hz single phase, suitable motor for electric traction is
- Braking retardation on suburban trains is
