Calculation of Cant Deficiency on Broad Gauge Rail Section
Given:
To find: Cant deficiency for the curve (in mm)
Solution:
Answer: Cant deficiency for the curve (rounded off to integer) = 57 mm
Given:
- Curve degree = 20
- Maximum sanctioned speed = 100 km/h
- Equilibrium speed = 80 km/h
- Dynamic gauge of BG rail = 1750 mm
To find: Cant deficiency for the curve (in mm)
Solution:
- Step 1: Calculation of cant deficiency at maximum sanctioned speed
- Formula for cant deficiency (CD) = (V^2 / 127R) - G
- Where V = speed in km/h, R = radius in meters, and G = gauge in mm
- For maximum speed, V = 100 km/h
- Formula for radius (R) = 127 / degree of curve
- Substituting the values, we get R = 635 m
- CD = (100^2 / (127 * 635)) - 1750
- CD = 66.44 mm
- Step 2: Calculation of cant deficiency at equilibrium speed
- For equilibrium speed, V = 80 km/h
- CD = (80^2 / (127 * 635)) - 1750
- CD = 57.44 mm
Answer: Cant deficiency for the curve (rounded off to integer) = 57 mm

Given :
Maximum sanctioned speed Vmax = 100 km/hr
Equilibrium speed 80 km/hr Veq = 80km/hr
Degree of curve, D = 20
Arc length, L = 30.5 m
We know that angle
∴ The cant deficiency for the curve is 57 mm (round off to integer).
Maximum sanctioned speed Vmax = 100 km/hr
Equilibrium speed 80 km/hr Veq = 80km/hr
Degree of curve, D = 20
Arc length, L = 30.5 m
We know that angle
∴ The cant deficiency for the curve is 57 mm (round off to integer).
