1. What is Cant Deficiency?

Definition: Cant Deficiency is the difference between the actual cant provided and equilibrium cant necessary for the maximum permissible speed on a curve.

Purpose: It helps railway engineers ensure safe and comfortable train operation on curved tracks.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( DCant \) — Cant Deficiency (%)
• \( eth \) — Theoretical Cant (%)
• \( eCant \) — Equilibrium Cant (%)

Explanation: The difference between the theoretical cant (what should be provided) and equilibrium cant (what is actually provided) gives the cant deficiency.

3. Importance of Cant Deficiency Calculation

Details: Proper cant deficiency calculation ensures passenger comfort, prevents excessive wear on tracks and wheels, and maintains safe operation speeds.

4. Using the Calculator

Tips: Enter the theoretical cant and equilibrium cant as percentages. Both values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical acceptable cant deficiency range?
A: For passenger trains, typically ±5% is acceptable, but this varies by railway authority.

Q2: What happens if cant deficiency is too high?
A: Excessive cant deficiency can cause passenger discomfort and increase wear on rails and wheels.

Q3: How is equilibrium cant determined?
A: Equilibrium cant is calculated based on train speed and curve radius using specific railway formulas.

Q4: Can cant deficiency be negative?
A: Yes, negative values indicate cant excess rather than deficiency.

Q5: Why use percentages for these measurements?
A: Percentages provide a standardized way to compare cant values across different track geometries.
