The department became Western Australian Government Railways (WAGR) in 1890. WAGR became Westrail in 1975 and continued to manage both passenger and freight rail services in Western Australia until 2000, when the freight business was sold to the Australian Railroad Group who operated it under the Australian Western Railroad brand. This business was purchased by Queensland Rail in 2006 and rebranded Aurizon in 2013. Westrail’s freight rail lines were leased to WestNet Rail, another subsidiary of the Australian Railroad Group. This business was acquired by Babcock & Brown in 2006 and sold again in 2010 to Brookfield Asset Management and rebranded Brookfield Rail. In July 2017 it was again rebranded as Arc Infrastructure.
