V/Line is a statutory authority that operates regional passenger train and coach services in the Australian state of Victoria. It provides passenger train services on five commuter lines and eight long-distance routes from its major hub at Southern Cross railway station in Melbourne. It also provides bus services across Victoria and into New South Wales, the Australian Capital Territory and South Australia. In addition, V/Line is responsible for the maintenance of much of the Victorian freight and passenger rail network outside of the areas managed by Metro Trains Melbourne and the Australian Rail Track Corporation.

The Victorian Railways (VR), trading from 1974 as VicRail, was the state-owned operator of most rail transport in the Australian state of Victoria from 1859 to 1983. The first railways in Victoria were private companies, but when these companies failed or defaulted, the Victorian Railways was established to take over their operations. Most of the lines operated by the Victorian Railways were of 5 ft 3 in. However, the railways also operated up to five 2 ft 6 in narrow gauge lines between 1898 and 1962, and a 4 ft 8+1⁄2 in standard gauge line between Albury and Melbourne from 1961.
