The Mildura railway line is a heavy rail line in northwestern Victoria, Australia. The line runs from Yelta station to Ballarat station via the settlements of Mildura, Ouyen and Maryborough in an approximate south-southeasterly direction. Initial sections of the line opened from Ballarat in 1874 and the line reached Mildura in 1903.

The Serviceton railway line is part of the Melbourne–Adelaide rail corridor. It serves the west of Victoria, linking the state capital of Melbourne to the cities of Ballarat and Ararat. It once extended to the disputed South Australian border as part of the Melbourne–Adelaide railway. The former broad-gauge track was replaced in 1995 by the 1435 mm Western standard gauge line.
