AN Tasrail was an Australian railway operator that operated the Tasmanian rail network from March 1978 until November 2004. Originally a subsidiary of the Federal Government's Australian National, it was sold to Australian Transport Network (ATN) in November 1997. ATN was acquired by Pacific National in 2004 and the AN Tasrail subsidiary was later acquired by the Tasmanian Government in 2009 to become TasRail.
