The Electric Multiple Units are a class of electric multiple units manufactured by Walkers Limited, Maryborough for Queensland Rail between 1979 and 1986. They were the first EMUs in Queensland and remain in service with Queensland Rail City network

All units feature air-conditioning, power operated automatic doors, fabric covered padded seating, passenger information displays, emergency intercoms and a public address system.

In 1977 Walkers Limited, Maryborough were awarded a contract to build 13 EMUs with electrical equipment to be supplied by ASEA. These were the first EMUs in Queensland, entering revenue service when the first part of the Brisbane rail network was electrified between Ferny Grove and Darra in November 1979. Further orders saw the fleet total with the last delivered in December 1987.

EMUs are still in frequent revenue service around South East Queensland. They operate on all Queensland Rail suburban lines in either three or six carriage sets. EMU01-EMU04, EMU06-EMU59 and EMU80-EMU88 have driving cabs at both ends and can either operate as three or six car sets. EMU60-EMU79 have only a single driving cab, and as a result, they can operate only as part of a six car set. EMU05 was extensively damaged in 2001 and is no longer in service.

Although intended only for suburban operation they are occasionally found operating interurban services, mostly on the Nambour & Gympie North line. EMUs are interoperable with InterCity Express units to form hybrid sets.
