1998 Concord West derailment

At approximately 4:25 am AEST on 9 June 1998, an eight-carriage CityRail Tangara T set consisting of two coupled individual sets derailed near Concord West station, an Inner West suburb of Sydney, Australia. The train was found to be travelling at an excess of 100 kilometres per hour (62 mph) while approaching Concord West station through the residential area, when the first carriage derailed, resting on its side after jackknifing.
