2003 Melbourne runaway train

On 3 February 2003, a Comeng electric multiple unit train rolled away from Broadmeadows station in Melbourne, Australia, before it ran for nearly 17 kilometres (11 mi) out of control without a driver and eventually crashed into another train about to depart Spencer Street station. Train controllers attempted several times to stop or redirect the train, but were limited in their ability to intervene, instead being forced to alter the route of other trains to avert a more serious collision. Eleven people on board the stationary train were injured; authorities did not know until after the crash if any passengers were on board the runaway. An investigation identified driver error as the cause of the accident, but the runaway event prompted significant debate about the role of government authorities and private operators in ensuring safety and reliability on the Melbourne rail network.
