The80 class are a class of diesel locomotives built byComeng for thePublic Transport Commission between 1978 and 1983.

The 80 class were built byAlco's Australian licenseeComeng as an evolution of the442 class. The 80 class were the first locomotives in Australia to feature factory-fitted cab air-conditioning andfibreglass body panels and the first in New South Wales delivered withoutbuffing plates.^[1] To reduce the need for repainting, the fibreglass panels were pre-coloured hence the class retained their original liveries for longer than had previously been the case.^[2][3]

An initial order of 30 was followed by an additional order for 20. The first order were delivered in Indian red livery while the second received thereverse livery with a yellow nose and Indian red wings. They were initially introduced on theMain South line before being transferred to the western region for use betweenLithgow andBroken Hill.^[2] They quickly spread and regularly hauled freight and passenger services on all main lines. Only three locomotives, 8015, 8018 and 8034, received the 1980s-era candy livery. Due to having been repainted after the rebranding of the State Rail Authority to FreightRail, they received small FreightRail logos on the cabsides. In 1988, to celebrate the Australian Bicentenary, 8010 and 8040 received a special livery.

After being fitted withAustralian National radios, 8034-45 commenced operating through toAdelaide withAustralian National ALs operating into New South Wales in 1990.^[4] Through working ceased in May 1991 when theAustralian Federated Union of Locomotive Enginemen placed a ban on the 80 class inSouth Australia.^[5]

Following the formation ofNational Rail, all were reallocated to the national operator in July 1995.^[6] This saw their sphere of operation extended toMelbourne, albeit as trailing locomotives.^[7]

Following National Rail taking delivery of theNR class locomotives, the 80s began to return toFreightCorp in January 1997. As they were surplus to requirements, some were placed in store.^[8] By April 1997, 30 were in store.^[9] In September 1997, 8015 and 8039 were loaned toBHP as a trial on services at theirPort Kembla steelworks. All were included in the sale ofFreightCorp toPacific National in February 2002.

In March 2003, 24 of the class were sold toSilverton Rail joining 8043 that had been sold to them in 1999.^[10] Four (26, 37, 44 & 49) were returned to traffic as 80s1, 80s4, 80s2 & 80s6. All were included in the sale of the business toCoote Industrial and laterQube Logistics. A fifth (8030) was returned to service in 2010 while the other four resumed their original identities. A few of the others have been scrapped with the remainder in store atBroken Hill,Parkes andWerris Creek.^[11][12] 8049 has since been sold toSouthern Shorthaul Railroad and is in service in NSW.

Pacific National operate 8011, 8025, 8033 and 8046 mainly as shunters at Keswick, Broken Hill and Morandoo with 10 in store atChullora and Werris Creek.
