The Piangil railway line is a 5 ft 3 in gauge (1600 mm) railway line in north-western Victoria, Australia. It branches off the Deniliquin line just north of Bendigo, and runs in a north-westerly direction through Pyramid Hill and Kerang to the border town of Swan Hill, then roughly parallels the New South Wales border to Piangil and Yungera. The line is now open only as far as Piangil, and passenger services only operate to Swan Hill.

The Deniliquin railway line is a broad-gauge railway line serving northwestern Victoria, Australia. The line runs from the New South Wales town of Deniliquin into Bendigo, before turning south-southeast towards Melbourne, terminating in Docklands near the central business district. It is a major trunk line both for passenger and freight trains, with many railway lines branching off from it.
