HistoryIn July 1984, a joint venture of Clyde Engineering and Walkers Limited was awarded a contract to build 70 3500/3600 class electric locomotives with ASEA supplying the electrical equipment. These were ordered to operate coal trains on the Blackwater and Goonyella railway lines that were in the process of being electrified.[1] The contract was later extended to 80. The bodies being built and assembled at Walkers's Maryborough factory with Clyde Engineering responsible for some of the electrical equipment and commissioning the locomotives.[2] Following the decision to electrify the North Coast line from Brisbane to Rockhampton, the last 30 were built to a modified design for passenger and general freight use, and delivered as the 3900 class. They received modified bodies to allow them to pass through Brisbane's tunnels and received higher gearing to allow them to operate at {{convert|100|km/h|abbr=on}}.[2][3] 3550 classWith an increased need for locomotives on the Central Queensland coal lines, 19 were converted to 3550 class locomotives.[4] References1. ^{{cite book|last=Oberg|first=Leon|title=Locomotives of Australia 1850s-2010s|year=2010|publisher=Rosenberg Publishing|location=Kenthurst|isbn=9781921719011|pages=403-405}} {{QueenslandLocos|state=collapsed}}2. ^1 {{cite book|last=Clark|first=Peter|title=An Australian Locomotive Guide|year=2012|publisher=Rosenberg Publishing|isbn=9781921719554|pages=353-354}} 3. ^Walkers/ABB 3900 Class Queensland's Railways Interest Group 4. ^3500/3600/3551 Class Railpage 6 : Aurizon electric locomotives|Bo-Bo-Bo locomotives|Queensland Rail locomotives|Railway locomotives introduced in 1988|Walkers Limited locomotives|3 ft 6 in gauge locomotives of Australia |
