Professor Colin Cole is the Director of the Centre for Railway Engineering (CRE), CQUniversity. He has worked in railway research for 28 years and published over 200 technical papers and numerous reports working mainly in train dynamics and condition monitoring. His PhD was on Longitudinal Train Dynamics, and he has continued to develop this modelling and software with focus on traction, vehicle stability, unloading systems and energy consumption. He has conducted a range of rail projects including field testing, simulation, intelligent systems and condition monitoring systems. Projects include both research and consulting with work both in Australia and internationally in Africa, China, India, Mongolia and USA. He has also experience in taking research through to commercialization phase involving patents, proof of concept and first product roll out. His more recent interest has focused on energy recovery, on-board energy storage battery electric locomotives and investigation of hydrogen options for the replacement of diesel powered locomotives.
