Qing Wu is a Principal Research Fellow and the Mechanical Discipline Leader at the Centre for Railway Engineering, Central Queensland University, Rockhampton, Australia. He commenced his railway studies in 2006 at Southwest Jiaotong University, China, and received his PhD in draft gear optimisation from CQUniversity in 2016. His research focuses on mechanical system dynamics, parallel computing, multi-objective optimisation, dynamic control, and their applications in railway vehicles, trains, and track systems. Dr Wu has led and contributed as Chief Investigator to projects across national competitive grants, state competitive grants, industry research grants, and consultancy programs. He is the recipient of an Australian Research Council DECRA Fellowship and an Advance Queensland Industry Research Fellowship, funded by the Australian and Queensland Governments, respectively. He has authored more than 240 scientific publications. In addition, he serves on the editorial boards of more than half a dozen academic journals. He is also a Chartered Professional Engineer and holds both RPEQ and RPEV registration in Australia.Colin Cole is Professor of Engineering and Director of the Centre for Railway Engineering at Central Queensland University, Rockhampton, Australia. He has worked in the Australian rail industry since 1984, starting with six years in mechanized track maintenance for Queensland Railways. Since then, he has focused on a research and consulting career involving work on track maintenance, train and wagon dynamics, train control technologies and the development of onboard devices. He has been extensively engaged with industry via the past nationally funded rail CRC programs and the Australasian Centre for Rail Innovation. His PhD was in longitudinal train dynamics modelling. He has authored and/or co-authored over 300 technical papers, three books, numerous commercial research and consulting reports and has developed two patents relating to in-cabin locomotive technologies. He has continued to develop railway and road-specific modelling and software tools with a focus on traction, vehicle stability and energy consumption. Prof. Cole is a Chartered Professional Engineer and RPEQ in Australia.
