‘Rescue’ Indian Railway passenger business through statistical indices ‘RSKU’

By on January 17, 2017

Is Indian Railway earning fully towards its non sub-urban passenger business? There is no published data to corroborate this. Interpreting it by the long waiting list is a wrong assessment. The waiting list continuing in 2016-17 even when there is a drop of 10% passenger as compared to 2012-13 and 10% increase in coach holding. […]

Weight Transfer during Braking

On application of brakes on the vehicle, inertia forces are set up. The braking force is applied at lesser height whereas the vehicle load is at a higher height, resulting a couple to act on the body of the vehicle. This results an additional loading on leading bogie as compared to trailing bogie. Let H […]
