Question
(a) Compare between DC and AC systems of railway electrification from the point view of main line and suburban line railway service. (10)
(b) An electric train is to have acceleration and braking retardation of $0.8\text{ km/h/s}$ and $3.2\text{ km/h/s}$ respectively. If the ratio of maximum to average speed is $1.3$ and time for stops $26$ seconds, find schedule speed for a run of $1.5\text{ km}$. Assume simplified trapezoidal speed-time curve. (10)
