This is the first of many posts i'll be making about how to improve the Melbourne railway network, line by line. So to start off, here are my suggestions for improving the Werribee Line
Duplication-As it isn't possible to duplicate the whole Altona Loop as it would require some compulsory acquisition of property, I have an alternative solution. Duplicate as far as Seaholme Station. There's enough room at Seaholme for a second track and platform, then duplicate Westona to Laverton. That way a train heading to Werribee won't have to wait for a Flinders Street train to pass.
Removal of level crossings-All level crossings along the Altona Loop can be easily removed. Pier Street level crossing can get busy I have noticed, and this would also enable buses to stick closer to their timetables. Maidstone Street at Westona gets really busy in peak hours I have noticed. Should be done alongside duplication.
New Stations-Now that the Altona Loop Bypass doesn't have to share the tracks with v/line trains, I think some stations can be added. The former Paisley Station can be reopened as Altona North. As the platform is still there, all that will be needed are some minor works to bring the station up to modern day standards. It should connect to the park and ride as well as the Homemaker Centre nearby, as well as the number of residents that live in the area, and is a short bus ride away from Altona Gate Shopping Centre.
Maidstone Street would be another good spot for a station, where the former Galvin Station used to be. The station could be called Maidstone Street, and would be a boon for the indutrial areas and houses around there, as well as the school down the road and Harrington Square as well.
Another station could also be built and Grieve Parade should the two halves ever be connected. It would be good for residents who live near there, such as myself. It would relieve pressure on The Altona Loop, provide people with more travel options, and it would somewhat relieve overcrowding.
And a station at Derrimut Road would be a good idea too.
Extension-Extend to Wyndham Vale to re-establish connection with v/line trains. There is some room behind Platform 2 at Wyndham Vale for an extension. I would imagine it was built that way for specifically that purpose. New Stations at Westleigh Gardens and Black Forest Road. I know the latter is on the cards anyway. This should be done as soon as it is feasible.
