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. Operated by the Victorian Railways and successors, the lines served the Yallourn Power Station, the associated open cut brown coal mine, and a briquette factory complex, all operated by the State Electricity Commission of Victoria (SECV), as well as the adjacent company town of Yallourn. The alignment of the first branch line has been lost due to the expansion of the Yallourn mine. The second line is now part of the Moe to Yallourn Rail Trail. History The first branch was opened in January 1922 to transport briquettes from the briquette production operations at Yallourn to Melbourne, in addition to transporting supplies to the power station located beside the coal mine. It left the main line at Hernes Oak, initially with a staff locked set of points and a loop siding. When traffic increased, that was altered to include a crossing loop, siding, and signal box. In later years, outward traffic from the briquette works increased, and an electrification program for the Gippsland line was put into place as part of Operation Phoenix. Further complications arose when expansion plans for the Yallourn open cut mine encroached on the alignment of the branch, and given the presence of 1:50 gradients on the line, it was decided to rebuild the line to Yallourn along a completely new alignment. Work started in 1949 but was hampered by labour shortages, and the new 9.7 kilometre branch, on a 1 in 110 grade, was brought into service in September 1953. The electrification of the new line was not commissioned until September 1955, when work on the main line to Melbourne had been completed. The old route via Hernes Oak was initially retained, being used by down empty to trains, with loaded trains using the new line to return to Melbourne. A new signal box at Yallourn marshalling yard was opened in December 1953, allowing two-way operation on the new line. The old line fell into disuse but was not removed until March 1957, when the SECV began to expand the Yallourn open cut
