I moved to the city from port Melbourne for work and have been using the train for 12 months after never using it since I was a teenager. That's a long time ago.
now I'm on vline on the Geelong line . Great seats some with fold down tables like a plane , toilets, drinking taps even has a quiet carriage. Got to say Ime impressed. Half the travel time maybe more. Use it now and then for the footy or a night on the town
Maybe the metro might not be so nice but the country train is okay
