1. What is Weight of Rail per Meter Calculator?

Definition: This calculator determines the weight of a single rail per meter based on the total weight of rails per kilometer, number of rails, and rail length.

Purpose: It helps railway engineers and construction professionals calculate rail weight distribution for track design and material planning.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( w \) — Weight of rail per meter (kg/m)
• \( W \) — Total weight of rails per km (tonnes)
• \( N \) — Number of rails per km
• \( L \) — Length of single rail (meters)

Explanation: The total weight is converted from tonnes to kg (×1000), then divided by the total length of all rails in a km.

3. Importance of Rail Weight Calculation

Details: Proper rail weight calculation ensures structural integrity, load capacity, and material optimization in railway track construction.

4. Using the Calculator

Tips: Enter the total weight of rails per km in tonnes, number of rails per km (±5%), and length of single rail (default 13m for broad gauge). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the number of rails per km given with ±5%?
A: This accounts for variations in rail spacing and installation tolerances in actual track layouts.

Q2: What's a typical rail length used in India?
A: Indian Railways standardizes 13m for broad gauge and 12m for MG/NG tracks.

Q3: What are common rail weights?
A: Common weights are 52kg/m (standard), 60kg/m (heavy duty), and 45kg/m (light rail).

Q4: How is total weight of rails per km determined?
A: It's calculated by multiplying the number of rails by their individual weights, or measured during procurement.

Q5: Does this calculation include rail joints?
A: No, the calculation assumes continuous rail weight. Joints would add minimal additional weight.
