Shouldn't Sydney and Melbourne have dedicated metro networks by now as in rapid transit? There are so many pro's...
Rapid transit/metros are faster
metro trains don't interact with mainstream traffic like trams and suburban commuter trains, which have to use level crossings, they are predominately underground
driverless
serve high density areas like the inner city suburbs with frequent stops, essentially like a tram, but underground
It seems that in the 70s, 80s and 90s Australian cities were focusing too heavily on roads and cars when they should have been prioritising better public transport and building metro lines. One academic said that Melbourne's public transport has not been adequately updated for decades, despite some "dressing up" of already existing infrastructure.
