Melbourne's tram network is a major form of transportation in Melbourne, Victoria, Australia, consisting of 24 tram routes. The system is owned by Public Transport Victoria. Yarra Journey Makers (trading as Yarra Trams), a joint venture of Transdev and John Holland Group, operates the network. The tram network consists of over 250 kilometres (160 miles) of duplicated track in all 24 routes, making it the largest tram network in the world.
The tram network consists of around 1,700 stops, with over 450 of them accessible to disabled passengers.
The tram network uses the Myki ticketing system, with the exception of the Free Tram Zone, which covers travel inside of the Melbourne CBD. The City Circle tourist tram also does not use Myki, as it is fully inside the Free Tram Zone. All tram routes are within fare zone 1, with some stops on routes 75, 86, and 109 being in the zone 1 and 2 overlap.
