The Albury ticket office will have a TOT (Ticket Office Machine) that will sell and reload cards (as well as sell short term tickets). The TOT is used by staff. There are no plans to install vending machines at most regional stations as staff will have enough time to sell and reload tickets. They'll have even more time as many regular users will already have myki cards and will choose to reload at retail agents, online, etc...
However, major V/Line stations in the commuter belt will have vending machines.
In metropolitan Melbourne we make about two thirds of our revenue from periodicals and bulk purchased tickets (with the number of people purchasing short term tickets - such as individual two hours tickets - shrinking fast).
One of the disadvantages that V/Line has faced is that if you have someone travelling three days a week - or only travelling one way as they get a lift in one direction - then all these customers need to line up to purchase a ticket each time they travel. These customers will transition over to myki pretty smoothly. So I'm expecting that this will reduce the size of the queues at the V/Line ticket office. This will obviously have bigger benefits in the V/Line 'commuter belt' - but that's good for long distance customers too as shorter lines at Southern Cross are good for everyone.
It will be VERY interesting how quickly the number of tickets sold by V/Line staff (both at stations and by conductors) will decrease. I'm expecting an initial fall in sales and then a slow decline in sales as customer switch to the new system.
