A comparison of bearing life in new and refurbished railway axle boxes [PDF]
A simple linear dynamical model shows that at normal running speeds of freight wagons, forced oscillations due to periodic track compliance are transferred to the overlying unsprung mass and significantly amplified. Due to these oscillations, a small gap

Analysis of Frictional Sliding Contact in Magnetic Track Brakes: A Simplified Methodology
ABSTRACT Magnetic track brakes (MTBs) serve as emergency braking systems in railway applications, relying on mechanical sliding contact between a braking element (the pole shoe) and the rail. Accurate and efficient prediction of both local and global contact forces, as well as the resulting deformations during braking, is crucial for optimizing overall
