non-air-conditioned wooden bodied passenger cars withdrawn from service in 1986, replaced by new "H" set carriages. Trials were also carried out for further upgrades, with locomotive A85 re-geared for 160 km/h operation in a series of test runs between Glenorchy and Lubeck in the state's west in July 1986. It was also the end of an era, with freight trains having their guards vans and guards abolished from 1985, and the carriage of livestock ended in 1986. The last run of the Spirit of Progress and Southern Aurora passenger trains were also made in 1986, on 3 August. Working practices were also altered, with through working of C class locomotives introduced between Melbourne and Adelaide in 1982. Previously Victorian locomotives were detached at the state borders, and replaced by locomotives from the next state. New locomotive were also introduced, with the G and N classes enabling the retirement of many of the 1st generation diesels. Cuts continued to the rail network, with larger centralised silos in the north western area of the state, and replacement of traditional safeworking systems by systems that required no local staff saw further stations de-manned. Privatisation The 1990s saw costs further reduced on the rail network. Guards were removed from passenger trains in 1989, and driver only suburban trains commenced running in 1993, with the last suburban train crewed by a guard running in November 1995. In 1994, the National Rail Corporation was established, taking profitable steel, and intermodal trafficks from V/Line; and the Melbourne to Adelaide standard gauge line was opened in 1995, removing the break of gauge. Moves towards privatisation began in 1997, with V/Line split into V/Line Passenger and V/Line Freight and Melbourne services operated by the Public Transport Corporation split into Bayside Trains and Hillside Trains. V/Line Freight was sold to Freight Victoria in 1999, followed by National Express taking over Bayside Trains and V/Line Passenger in 2000, with Connex Melbourne taking over Hillside Trains. End of private lease Victorian Premier Steve Bracks negotiated a premature end to the "under-rail" Victorian country Broad Gauge network lease just minutes before the caretaker mode began before the state election of November 2006. This cost around $125 million. In May 2008, Premier John Brumby arranged a 45-year lease to the Australian Rail Track Corporation of the single track Seymour-Albury section. Part of the negotiation involved Victoria contributing money for the track to be upgraded
