[edit]

The GT42CU ACe is an evolution of the GT42CU AC being fitted with a different computer system and traction motors.[1]

In Early 2024, Aurizon order for 54 Locomotives Type Used In Queensland. These were designated as the 4100 class.[2] In Early 2012 Aurizon, Remains 19 Locomotives type In Western Australia and reclassified as the ACN class. In Early 2025 Purchased 2 Locomotives type they were returned into Queensland.[3]

The Queensland based units are primarily used on the Blackwater, Moura and Newlands coal networks, and on phosphate trains between Mount Isa and Townsville. The Western Australian-based units are primarily engaged hauling iron ore trains. All were included in the transfer of Queensland Rail's freight business to Aurizon in Dec 2012.

Pacific National placed an order for 13 units for coal haulage on the Blackwater system that later grew to 46. These were designated as the 83 class.[4]

In Early 2022, Magnetic Rail order 5 locomotives type Used In Queensland.[5] Designated the GWN class, used on the Blackwater, Moura and Newlands coal networks.[6][7] In Early 2022 5 Queensland Railways 2250 class type locomotives for use in South Australia operated on the Arrium iron ore railway to Whyalla Steelworks.

A further six were built as a speculative order for Locomotive Demand Power as the LDP class.[8] One was painted in Pacific National livery and numbered 8347 in anticipation of a lease that failed to eventuate, the others were numbered LDP016-LDP020 with all six placed in store in Maryborough. All were included in the sale of Downer Rail's locomotive business to Progress Rail Services and in December 2017, were moved to Redbank Railway Workshops entering service as 8347–8352 with Pacific National in April and May 2018.[9][10]
