Download Solution PDFThe value of dynamic gauge (G) used to calculate the super elevation is ________ for broad gauge railway tracks.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
The equilibrium superelevation (\(e\)) is calculated using the following formula:
\(e = \frac{GV^2}{127R} \)
Where:
\(e=\) Superelevation in millimeters (mm)
\(V=\) Speed in kilometers per hour (km/h)
\(R=\) Radius of the curve in meters (m)
\(G=\) Dynamic gauge in millimeters (mm)
Dynamic Gauge (G):
The dynamic gauge (G) equal to the sum of the gauge and the width of the rail head in millimeters.
For Broad Gauge (BG) tracks: \(G = 1750 \ \text{mm} \)
For Meter Gauge (MG) tracks: \(G = 1080 \ \text{mm} \)
