You've edited Flagstaff station in Arizona, United States (https://www.openstreetmap.org/way/453586544/history/6#map=19/35.197405/-111.648589) in addition to the one you probably wanted to edit in Melbourne, Australia. I'd assume VIC DTP isn't intentionally editing in the US, so I've assumed this is a mistake and have reverted the changes in the US (https://www.openstreetmap.org/changeset/172430435).
