This paper is the first of a two-part review of train aerodynamics. After an initial introduction
and broad survey of train aerodynamic issues, and a discussion of measurement, modelling …

This paper is the second part of a two-part paper that presents a wide-ranging review of train
aerodynamics. Part 1 presented a detailed description of the flow field around the train and …

This paper presents the design, modeling, lab test and field demonstration of a railroad
energy harvester featuring rapid anchorless mounting. By harvesting energy from rail track …

Slipstream, which is the induced air movement generated by a high-speed train (HST) as it
passes, is both a safety hazard to commuters and trackside workers, and can cause damage …

Anelectromagnetic energy harvester is designed to harness the vibrational power from
railroad track deflections due to passing trains. Whereas typical existing vibration energy …

The influence of ground clearance on the flow around a simplified high-speed train is
investigated in this paper. Four clearance heights are studied using IDDES. After a grid …

Ballast flight is a significant safety problem for high-speed ballasted tracks. In spite of the
many relevant prior studies, a comprehensive review of the mechanism, recent …

To mitigate the ballast flight risk in the high-speed railway, this paper presents three new
polyurethane bonding schemes which have negligible influence to tamping operations. With …

Traditional ballasted tracks have been used intensively around the world with ballast as the
main material for tracks. Ballast has a significant contribution to the track alignment, stability …

Maintenance and eventual renewal of a ballasted track constitute major operational costs for
a railway network. Thus, significant benefits would accrue from a more robust track design …
