The Electric multiple unit (EMU) is a class of electric multiple units manufactured by Walkers, Maryborough for Queensland Rail between 1979 and 1986. They were the first EMUs in Queensland and some remain in service on the Queensland Rail City network. The units are now progressively being replaced by newer NGR fleet though some still remain in service today.
Accidents: On 23 March 1985, two EMUs collided head-on near Trinder Park. A train driver and passenger were killed, and 31 others were injured. The units involved, EMU11 and EMU27, were both were repaired by Walkers and returned to service in December 1985.
On 14 March 1996, EMU28 derailed after hitting a freight train near the former Mayne Junction station. EMU28 was later repaired and returned to service.
On 21 September 2001, a freight train hauled by 3906 derailed near Petrie and collided with two empty EMUs, EMU05 and EMU60. Two carriages from EMU05 and one carriage from EMU60 were condemned and scrapped, with the remaining car from EMU05 (EM305) replacing EM160. In 2020 EMU60 was scrapped as part of the EMU retirement and recycling program.
Disposition: When a unit is condemned to being disposed, EMU units are often sent to the Port of Brisbane where they will be earthed until being transferred to the Ipswich Railway Workshops. Upon arrival, Workshop staff will begin taking away the units wires and electrical components in a process known as stripping. When stripping is complete, the units are then flattened to be placed into metal bins where they will be loaded onto a truck and taken away.
