A substation and a short section of the overhead wiring, both of which are listed on the Victorian Heritage Register, have been retained to the west of the station.[2]
The line through Bunyip was electrified in July 1954, but the electrification was switched off between Bunyip and Warragul in December 1998, and between Pakenham and Bunyip in 2005, as part of the Regional Fast Rail project.[1] The track up to the western (up) end of the station was duplicated in 1956.
In 2022, as part of the Regional Rail Revival project, the former goods and stock platform and crane were removed to make way for duplicated track and a new second platform.[5] The siding for the goods platform was removed in April 1988.[6]
In April 2017, the Victorian state government announced an upgrade project to the Gippsland line as part of the Regional Rail Revival package. A second platform would be constructed at Bunyip, along with duplicated track from Bunyip to Longwarry.[7] However, it was reported in May 2022, that track would not be duplicated over the Bunyip River.[8] The new platform, renumbered to Platform 1, opened on the 13 June 2024. The original platform was renumbered to Platform 2.[9]
