One of the racers featured here, Kevin, has done that, although on a previous iteration of the Sydney rail network - the Carlingford Line still existed and the Metro from Epping to Tallawong did not, ergo, 178 stations. His Sunday Timetable time was 16h22m13s on 29/9/18. Nobody has tried the present-configuration 180 stations because finding a weekend without trackwork is impossible.
