DOI: 10.1016/j.compstruct.2021.113851
Abstract: Abstract The potential for lightweighting of railway axles was investigated to primarily reduce the unsprung mass of a rail vehicle. The reduction of unsprung mass equates to an overall lighter train which will help to… read more here.

DOI: 10.1177/0954409719831822
Abstract: Defects in railway axle bearings can affect operational efficiency, or cause in-service failures, damaging the track and train. Healthy bearings produce a certain level of vibration and noise, but a bearing with a defect causes… read more here.
