The Western railway line is a narrow gauge (1,067 mm or 3 ft 6 in) railway, connecting the south-east and south-west regions of Queensland, Australia. It commences at Toowoomba, at the end of the Main Line railway from Brisbane, and extends west 810 km to Cunnamulla, passing through the major towns of Dalby, Roma and Charleville, although services on the 184 km section from Westgate to Cunnamulla have been suspended since 2011. The Queensland Government was the first railway operator in the world to adopt narrow gauge for a main line, and this remains the system-wide gauge.
