Two different railway lines serviced Yallourn during its existence. Both were broad gauge branches from the main Gippsland line in Victoria, Australia. The first was a line branching from a junction at Hernes Oak, situated between Moe and Morwell, which was in service from 1922 to 1955. The second Yallourn railway line junctioned at Moe, and was used between 1953 and 1986.
