Rail transport in the Australian state of Victoria is provided by a number of railway operators who operate over the government-owned railway lines. The network consists of 2,357 km of Victorian broad gauge (1,600 mm (5 ft 3 in)) lines, and 1,912 km of standard gauge (1,435 mm (4 ft 8+1⁄2 in)) freight and interstate lines; the latter increasing with gauge conversion of the former. Historically, a few experimental 762 mm (2 ft 6 in) gauge lines were built, along with various private logging, mining and industrial railways. The rail network radiates from the state capital, Melbourne, with main interstate links to Sydney and to Adelaide, as well as major lines running to regional centres, upgraded as part of the Regional Fast Rail project.
