Question

The limiting value of cant excess for Broad Gauge is

• A. 45 mm
• B. 55 mm
• C. 65 mm
• D. 75 mm

Hint:

- Cant excess must be within permissible limits to prevent excessive lateral forces on the rails, which can cause derailments. - For Meter Gauge (MG), the limiting cant excess is usually lower than Broad Gauge.

Answer 1

The Correct Option is C

Step 1: Definition of Cant Excess Cant excess is the difference between the actual cant provided on a railway track and the equilibrium cant needed for a given speed and curvature. Step 2: Standard Limiting Value for Broad Gauge As per Indian Railways standards, the maximum cant excess permissible for Broad Gauge (BG) tracks is 65 mm. This is to ensure a safe and smooth ride while maintaining track stability. Step 3: Conclusion Since the maximum permissible cant excess for Broad Gauge is 65 mm, the correct answer is (C) 65 mm.
