Building on an initial ACRI review, with use of simulation and modelling, to research the additional track maintenance efforts that may be required with modern AC locomotives that have higher levels of traction compared with existing DC locomotives currently in operation on heavy haul routes. Increasing knowledge of maintenance requirements will deliver greater rail operation efficiencies.

Moving in line with the findings of the outcomes of Stage I, the research direction in this project would be to investigate wear processes between wheels and rails by means of the application of advanced simulation approach that include longitudinal train dynamics and improved multibody simulation approaches.

This research aims to produce a clear indication on the influence of modern high adhesion locomotive traction on wear, and damage for wheels and rails under different train operational scenarios, different contact characteristics and dynamic loads.

Increasing knowledge of maintenance requirements will deliver greater rail operation efficiencies.
