Riverline, also known as the Northern Suburbs Railway, was a proposed light rail system that would have traversed the southernmost section of the South Railway Line, through the northern suburbs of Hobart, Tasmania.

The South Line, also known as the Main Line and sometimes the North/South Line or the North–South Line, is a rail corridor connecting Hobart to the northern ports of Tasmania. The Railway Line was built by the Tasmanian Main Line Company.
