Design Loads on Railway Substructure: Sensitivity Analysis ...
substructure of a railway track, are presented in this paper. A method for the calculation of loads and stresses on a railway track was developed as a result of this research (Giannakos, 2004). This method together with three meth-ods found in the international literature are used to calcu-late the stresses on the track substructure and the results

Fundamentals of Railway Bridge Engineering and …
Learn about basic railway bridge engineering and design under the AREMA Manual for Railway Engineering, and the latest design procedures, materials, and methods used in current railway bridge engineering practice. You will also learn the requirements for compliance with FRA 237, including bridge ratings and bridge management. Additionally, the course will include a special section on drone ...
Characterization of railway substructure using a …
Changes in substructure conditions, such as ballast fouling and subgrade settlement may cause the railway quality deterioration, including the differential geometry of the rails. The objective of this study is to develop and apply a hybrid cone penetrometer (HCP) to characterize the railway substructure.
Types of Superstructure - Superstructure :: …
The superstructure is the upper part of the entire railway body and lies on the substructure. All construction elements below the formation protection layer(s) are part of the substructure. This includes earthworks, drainage systems and engineering structures. …

WO1998020203A1 - Railroad substructure - …
The present invention pertains to a railroad substructure built according to the continuous line laying method and characterized in that both the two rails defining the railroad and the side peripheral areas located below the head of rail rest on elastic intermediaite layers (3) against the inner side peripheral areas of a framework consisting of two framework halves (4, 5).
