Total Train Resistance

Go Total Train Resistance = 0.0016*Weight of Train+0.00008*Weight of Train* Speed of Train+0.0000006*Weight of Train*Speed of Train^2

Resistance due to Acceleration

Go Resistance due to Acceleration = (0.028*Weight of Train)*(Final Velocity of The Train-Initial Velocity of Train)/(Time Taken to Achieve Final Velocity)

Distance Travelled by Outer Wheels of Railway Vehicle

Go The Distance Travelled by Outer Wheels = (Mean Radius of The Curve of Railway Track+(Gauge of Track/2))*(Angle Substended by Axle of Railway Vehicle)

Distance Travelled by Inner Wheels of Railway Vehicle

Go The Distance Travelled by Inner Wheels = (Mean Radius of The Curve of Railway Track-(Gauge of Track/2))*(Angle Substended by Axle of Railway Vehicle)

Coefficient of Friction for given Hauling Capacity of Locomotive

Go Coefficient of Friction for Locomotive = Hauling Capacity of a Locomotive/(Weight on Driving Axle*No of Pairs of Driving Wheels)

Hauling Capacity of Locomotive

Go Hauling Capacity of a Locomotive = Coefficient of Friction for Locomotive*Weight on Driving Axle*No of Pairs of Driving Wheels

Resistance Due to Gradients

Go Resistance due to Gradients = Weight of Train*(Slope Percentage/100)

Wind Resistance

Go Wind Resistance = 0.000017*Exposed Area*Velocity of Wind^2

Go Resistance due to Starting for Train Vehicle = 0.005*(Weight of Train)

Hauling Capacity of Locomotive Formula

Hauling Capacity of a Locomotive = Coefficient of Friction for Locomotive*Weight on Driving Axle*No of Pairs of Driving Wheels
Hc = μ*w*n

Example Problem

Find out the hauling capacity of a locomotive with 3 pairs of driving wheels and an axle load of 20 tonnes. Use 0.2 as coefficient of friction.
solution:
Total load on driving wheels=3*20*1000
=60000Kgs
Hauling Capacity=0.2*60000=12000Kgs
Hauling Capacity of a locomotive=12 tonnes
