Rio Tinto, an Australian-British multinational and one of the world's largest metals and mining companies, has just successfully completed its first uncrewed train journey, travelling around 100 kilometres (62 miles) without a human on board. The journey took place at Rio Tinto's iron ore operations in the Pilbera region of Western Australia with the train travelling from Wombat Junction to Paraburdooand, and represents a big step towards the company's plans to have a fully autonomous train network by late 2018. The company has been using autonomous trains since earlier this year, with about 50 percent of its train operations being completed autonomously, but with drivers present at all times.
