The City Loop (originally called the Melbourne Underground Rail Loop or MURL) is a mostly-underground, partly surface-level and partly elevated subway and rail system around the central business district of Melbourne, Victoria, Australia.
The loop includes the city's two largest (both above-ground) stations: Flinders Street and Southern Cross (formerly Spencer Street); and three underground stations: Flagstaff, Melbourne Central (formerly Museum) and Parliament.
