What is it about?

The potential for lightweighting of railway axles was investigated to primarily reduce the unsprung mass of rail vehicles. The reduction of unsprung mass equates to an overall lighter train, which will help to reduce track damage, energy consumption and total operating costs. Two approaches were considered for the lightweighting of railway axles, which include a hollow axle design and material substitution using advanced composite materials, to offer a more track-friendly design.

This was my first published peer-reviewed journal paper that I wrote with my supervisor Dr. Michael Johnson. This article is the first output of my research concerning lightweighting of railway vehicles using composite materials.
