EDI/EMD PRQ Class
There's only one PRQ: PRQ001, which used to be Aurizon's 4000 class 4017. It's a GT42CU AC built by EDi Rail at Maryborough that started with Queensland Rail in September 2000. Progress Rail bought it off Aurizon and it took on its new number in 2025. Around the same time another 4000, 4026, went to One Rail as ORQ026.
