On the damaging effects of the ballast tamping operation
The performance of ballasted railway tracks is largely controlled by the condition of the ballast bed. As shown on figure 1, a typical active railroad cross-section is... -
Modeling of the dynamic response of ballast in high-speed train structures
The travelling of high-speed trains on ballasted tracks creates geometrical disorders, which are found to evolve fast with the traffic loading as compared to the...
