Some have merit, Hurstbridge line removal is good for the most part, although I reckon you could keep Diamond creek.As a regular traveller on the Sunbury Line I would say now that the distance between Middle and West Footscray stations has increased since the Regional Rail construction and the rebuilding of West Footscray station by observation the number of people using Middle Footscray has increased significantly.
Belgrave line is a little more interesting to me, Tecoma gets jack for patronage and should be closed, but I think keeping the rest of the line has merit, Belgrave is an ideal interchange while Upwey could get patronage.
Williamstown line I agree with, useless as all hell most of the time.
The Altona loop is ok for the most part, keeping up with James' idea it could be extended to Point Cook I guess, but closing it is ok too.
Upfield station is a fairly decent interchange for buses, and could give an alternative for the Busy Craigieburn line, I'd say keep it.
Jacana is a good candidate for closure, pretty useless position, same for Aircraft although its a little easier to reach then Williams landing or Laverton, and there's already three less stations on the line so you can keep it.
Glenbervie I'm not too sure about, sane for Fawkner, although middle Footscray is very useless and could be closed with no repercussions.
Rushall can be closed when they straighten out the line, but I disagree with Bell, should stay on Bell street and is far from Preston station.
Westgarth should stay while Dennis gets closed, Westgarth is in a better area compared to Dennis
Don't close both Darebin and Alphington, just closed Darebin and keep Fairfield where it is (since there's no longer a Dennis station)
Chatham I agree with, but not so much on Mont Albert, I reckon its fine.
Willison is stupid get rid of it, close both Hartwell and Burwood and form a new station at Toorak road, and close Alamein.
Overall, most are pretty justified, although a few odd ones here and there.
I do not now think Middle footscray should close .
