Question

a train engine with mass 200000 kg moves on a horizontal track with velocity 67.75 km/hr .if the resistance produced by the track is 85 n/kg, find power developed by the engine​

Answer 1

Explanation:

A short line railroad or branch line with the same tractive effort requirements might require up to 2000 horsepower to move the train because of the higher speeds involved. Main line locomotives may need over 4000 horsepower each with multiple units because of both high tractive effort and speeds.
