It’s 6:09 AM January 18th 1977 Mt Victoria train station in the Blue Mountains west of Sydney. The NSW 46 Class locomotive No.4620 hauling 8 passenger carriages leaves the station with commuters on their way to work in the city, a 126km journey. Along the way it will pick up and set down passengers. After stopping at Parramatta, it had a nonstop run to Strathfield then onward to Sydney. However, minutes out of Parramatta, a combination of factors would cause Australia’s worst ever train accident.
