‘Turnaround’ of Indian Railways: Increasing the Axle Loading [PDF]

Axle loading had contributed significantly to the ‘turnaround’ of the Indian Railways (IR) in the two years 2004-06. As the Minister of Railways (MR) stated, “A one ton extra loading per wagon implied additional revenue of Rs 500 crore per annum for IR.”

Geotechnical Properties of Ballast and the Role of Geosynthetics [PDF]

, 2006
The ballast and its engineering behaviour have a key role in governing the stability and performance of railway tracks. The deformation and degradation behaviour of ballast under static and dynamic loads was studied based on large-scale triaxial testing.
