Locomotive wheel polygonisation due to discrete irregularities: simulation and mechanism

, 2020
Discrete irregularities are a common issue occurring on locomotive wheels. The wheel roughness measured in the field sites indicates that some wheels suffer from discrete wheel irregularities, such as wheel flats or local defect.

Effect of Rail Irregularities on Ride Comfort of Train Moving Over Ballast-Less Tracks

International Journal of Structural Stability and Dynamics, 2019
Rail irregularities are the main factors influencing the ride comfort of trains moving over tracks. Despite various investigations made in this regard for the ballasted tracks, there is a lack of studies for the ballast-less tracks.
