BHP blames driver error, brake problem for runaway train wreck

BHP said on Friday that driver error caused an iron-ore train to run away without its driver and a brake problem caused the company to intentionally derail the train in order to stop it, according to a preliminary investigation. BHP said its initial findings of the November 5 incident showed the nearly 3-km long train came to a halt after a braking system control cable became disconnected. After the driver got off the train to carry out an inspection, it began to move "becoming what is termed a 'rollaway' train".
