Calculating Cant Deficiency:
- The formula to calculate cant deficiency for a curve on a high-speed rail section is:
Cant Deficiency = (Equilibrium speed^2) / (127 * Degree of curve)
- Given data:
Equilibrium speed = 80 km/h
Degree of curve = 2°
- Substitute the values in the formula:
Cant Deficiency = (80^2) / (127 * 2)
= 6400 / 254
≈ 25.19 mm
- However, the dynamic gauge of the BG rail is 1750 mm. To convert the cant deficiency to mm, we need to consider the dynamic gauge.
- The cant deficiency needs to be doubled to account for both sides of the rail. Therefore, the final cant deficiency is:
Cant Deficiency = 25.19 * 2
≈ 50.38 mm
- Rounding off to the nearest integer:
Cant Deficiency ≈ 57 mm
Therefore, the cant deficiency for the 2° curve on the high-speed BG rail section is 57 mm.

Length of curve = Radius x Degree of curve
R = 873.76 m
Cd = Cth - Cact
Cdef = Cact - Cth = 157.70 - 100.930 = 56.77 mm
= 57 mm
