Question

A 200-tonne electric train runs according to the following quadrilateral speed/time curve: 1. Uniform acceleration from rest at 2 km/h/s for 30 seconds 2. Coasting for 50 seconds 3. Duration of braking: 15 seconds If up-gradient is = 1%, train resistance = 40 N/t, rotational inertia effect = 10%, duration of stops = 15 s and overall efficiency of gear and motor = 75%, find schedule speed and specific energy consumption.
