 The impact of the crash broke the couplings between the fifth and sixth wagons of the goods train, and with the diesel locomotives still powering, what was left of the driverless goods train continued on its way.It travelled along the Broadmeadows to Albion goods line to Sunshine, where it was diverted on to another goods-only goods line.From there it continued through the Bunbury Street tunnel and negotiated a number of 40 km/h reverse curves, before being diverted by a signalman at South Kensington into a siding, where it collided with six goods wagons loaded with flour.
