Autonomous vehicles (AVs) have gained significant media attention and investment in recent years, with an estimated industry value of $US77 billion by 2035. However, many of the future challenges facing the AV industry have largely been experienced by the railway industry, in the form of Automatic Train Control (ATC), Automatic Train Operation (ATO) and related subsystems. Can existing railway systems provide solutions to these problems, and if so, how can railway engineers and organisations tap into this growing market? This technical paper will highlight the technological similarities between railway networks and the future AV market, focusing on the need for an omnipresent and reliable communications network and protocols to carry safety critical information. Opportunities for shared learnings are identified, and a likely roadmap to the meeting point between the two industries is discussed.
