Though the weight of the rail and its section depends upon various consideration, yet the heaviest axle load which the rail has to carry plays the most important role. The following is the thumb rule for giving the maximum axle load with relation to rail section:
- Maximum Axle Load = 560 X sectional weight of rail in lbs per yard or Kg per metre.
- Max. Axle load for 90lbs rail = 560 X 90 = 50400lbs = 22.50 Tons
- Max. Axle load for 52Kg rail = 560 X 52 = 29.12 MT.
