Modal identification of single-span railway viaducts [PDF]

, 2005
The paper reports on the results of the modal identification of several small to medium span railway viaducts. The identification was based mainly on the free vibration of each structure immediately after the train passages.

Performance Evaluation of Nigeria Railway Track Ballast Under Simulated Operational Conditions

Advances in Civil Engineering
Over time, most research on railway track performance has focused mainly on rail and track geometry, with a few considering the damage or degradation occurring at the substructure level.

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.

Comparison of approaches to assessing ballast layer contamination using ground penetrating radar

International Journal of Transportation Science and Technology
The railway ballast layer plays an important role in the functioning of the entire track structure as a whole, provides the connection of the rail-sleeper grid with the roadbed and its stability in the longitudinal and transverse directions.

‘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.”
