Calculation of Ruling Gradient on Curved Tracks
Ruling Gradient:
Ruling gradient is the steepest gradient on a section of a railway track that is found in the direction of maximum ascent. It is the maximum gradient allowed for a section of track.
Formula for Ruling Gradient:
Ruling gradient = Rise / Length x 100
Given data:
Ruling gradient on a particular section of track = 1 in 200
Curve in the track = 30 degrees
Calculation of Allowable Ruling Gradient on 30-degree Curve:
Formula for Allowable Ruling Gradient on Curved Tracks:
Allowable ruling gradient = Ruling gradient + (Superelevation / Length x 100)
Superelevation:
Superelevation is the banking of the outer rail of a curved track to counteract the centrifugal force on a train when it moves around a curve. It is expressed as a percentage of the height of the rail.
Formula for Superelevation:
Superelevation = (V^2 / 127R) x 100
Where V = speed of the train in km/h and R = radius of the curve in meters
Calculation of Superelevation on 30-degree Curve:
Given data:
Speed of the train = 40 km/h
Radius of the curve = (1000 / 30) meters (1 degree = 1000 / 360 meters)
Radius of the curve = 33.33 meters
Formula for Superelevation:
Superelevation = (V^2 / 127R) x 100
Superelevation = (40^2 / 127 x 33.33) x 100
Superelevation = 3.17%
Calculation of Allowable Ruling Gradient on 30-degree Curve:
Formula for Allowable Ruling Gradient on Curved Tracks:
Allowable ruling gradient = Ruling gradient + (Superelevation / Length x 100)
Given data:
Length of the curve = 100 meters (assumed)
Allowable ruling gradient = 1 / 200 + (3.17 / 100 x 100)
Allowable ruling gradient = 0.005 + 0.0317
Allowable ruling gradient = 0.0367
Allowable ruling gradient = 0.0367 x 100
Allowable ruling gradient = 3.67%
Therefore, the allowable ruling gradient on a 30-degree curve in a meter gauged railway track is 0.41%.
