History

The 1450 class was an evolution of the 1400 class, being built as a Co-Co instead of an A1A-A1A. This increased the weight by 14 tonnes (13.8 long tons; 15.4 short tons) but improved the tractive effort.^[1] They mainly operated in South East Queensland.^[2][3] To accommodate the Co-Co bogies, the unit was lengthened on both ends. The Sarmiento Railway in Argentina operated similarly-lengthened G12s, officially designated the GR12. The South American units differed from the Australian ones in having only the No. 1 end hood lengthened. The first was withdrawn in December 1986. Three have been preserved by Queensland Rail's Heritage Division, and are stored at Workshops Rail Museum, North Ipswich:^[4]
