The Electric multiple unit (EMU) is a class of electric multiple units manufactured by Walkers at Maryborough for Queensland Rail between 1979 and 1986. They were the first EMUs in Queensland and are progressively being retired from the Queensland Rail Citytrain network.

History

To provide rolling stock for the electrification of the Ferny Grove and Darra section of the Brisbane rail network, in 1976 Queensland Rail issued a tender for 13 three-carriage electric multiple units. [2] Bids were received from Clyde Engineering, Comeng, General Electric, Goninans and Walkers, with the latter awarded the contract with electrical equipment to be supplied by ASEA. [3] [4] [5] The first was delivered in May 1979, entering service on 17 November 1979 with all in service by October 1980. [6] [7] [8]

Before the first had been delivered, a further 11 units were ordered for the electrification of the Shorncliffe to Kingston section. [9] [10] [11] The first was delivered in November 1980. [12] These differed from the first order by having longitudinal ribs in the panels above the windows. [13] [14]

In February 1981, a further 36 three-carriage units were ordered to provide rolling stock for electrification of services to Petrie and Lota. [15] [16] The last 20 were built with one cab, requiring them to operate as six-carriage units. The fibreglass cab moulds were still fitted at the non-driving end, but not fitted out. [17] These had only six powered axles, versus eight when two of the dual cab units operated in six-car formation. [18]

Further orders for 16, eight and four units were made in 1983, 1984 and 1985, bringing the total ordered to 88 with the last delivered in December 1986. [19] [20] [21] [22]

In September 1986, units 84, 85, 86 and 88 were hauled to Gladstone to operate a VIP train to Rockhampton in connection with the completion of an electrification project, before operating some special services to Bajool and Mount Larcom. [23] [24]

units 81–88 were fitted with VHF radios to allow them to operate Sunshine Coast line services from Caboolture to Nambour from 29 April 1988, pending the delivery of the InterCity Express fleet. [25] [26] [27] Others did appear on Sunshine Coast services with hand held radios, while 84 and 68 ran through to Gympie North in August 1990. [28] [29] After the InterCity Express units entered service in September 1988, EMUs operated in multiple with them for a period. [30]

In 1996, some appeared on Gold Coast line services, although they were only used sparingly, not being geared to operate at the 140km/h line speed. [31]

Following the introduction of the New Generation Rollingstock (NGR) fleet in 2017, withdrawals began in 2018 with EMU06 the first taken to North Ipswich Railway Workshops for stripping. [32] By January 2019, 30 were in store. [33] Originally it was envisaged all would be withdrawn once all of the NGRs had been delivered, but the remaining EMUs have no scheduled retirement date as of yet. [34] [35]

In August 2019, Queensland Rail operated a farewell tour with units 01 and 04 over two days covering all Brisbane suburban lines including a reenactment of the first electric train service in Brisbane from Ferny Grove to Darra. [36] [37] [38] Both units were removed from service and taken to Ipswich Workshops for static preservation. [35]

Accidents

On 23 March 1985, two EMUs collided head-on near Trinder Park. [39] 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. [40]

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. [41]

On 21 September 2001, a freight train hauled by 3906 derailed near Petrie and collided with two empty EMUs, EMU05 and EMU60. [42] 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.

Queensland Rail (QR) is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates local and long-distance passenger services, as well as owning and maintaining rolling stock and approximately 6,600 kilometres (4,101 mi) of track and related infrastructure.

The Lancashire and Yorkshire Railway (LYR) built suburban electric stock for lines in Liverpool and Manchester. The line between Liverpool to Southport began using electric multiple units (EMUs) on 22 March 1904, using a third rail 625 V DC. Additional trains were later built for this route, and in 1913 incompatible stock for the route to Ormskirk. Lightweight units were built to run on the Liverpool Overhead Railway.

<span class="mw-page-title-main">British electric multiple units</span> British self-powered electric trains

An electric multiple unit (EMU) is an electric self-powered train, capable of operating in multiple with other EMUs and without the need for a locomotive; these are typically passenger trains with accommodation in every vehicle and a driving position at each end. The term can also be used to describe a train that is a permanent formation with a non-driving power car, such as the Advanced Passenger Train. As of December 2010, two-thirds of the passenger carriages in Great Britain are formed in EMUs.

<span class="mw-page-title-main">Electric multiple unit</span> Electric train with no locomotive

An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a number of the carriages. An EMU is usually formed of two or more semi-permanently coupled carriages, but electrically powered single-unit railcars are also generally classed as EMUs. The great majority of EMUs are passenger trains, but versions also exist for carrying mail.

The first railway in Sydney was opened in 1855 between Sydney and Granville, now a suburb of Sydney but then a major agricultural centre. The railway formed the basis of the New South Wales Government Railways. Passenger and freight services were operated from the beginning. By 1880, there was a half hourly service to Homebush.

The Tze-Chiang Express, also spelled "Tzu-chiang" or "Ziqiang" is a type of express train service operated by the Taiwan Railways Administration (TRA) in Taiwan. Of the five service classes operated by the TRA, the Tze-Chiang trains is the fastest category. Ticketing is done on the basis of mileage. This service is operated with 7 different trainsets: the E1000 series, the EMU1200, EMU3000, TEMU1000, DR2800, DR3100, and the TEMU2000. The now-retired EMU100 was the first trainset built for this service, which was used for 30 years, terminating ordinary runs at June 15, 2009.
