Measurement methods and analysis tools for rail irregularities. A case study for urban tram track [PDF]
Rail irregularities, in particular for urban railway infrastructures, are one of the main causes for the generation of noise and vibrations. In addition, repetitive loading may also lead to decay of the structural elements of the rolling stock.

Vibration Mitigation Effect Investigation of a New Slab Track Plate Design
This study proposed a novel vibration mitigation slab track plate design to mitigate the vibration induced in urban rail transit operations. The optimal recipe for the newly designed slab track plate is obtained by a series of laboratory tests, and both ...
