Railway St Nth and Sth, from Greive Pde to Westona, limit ground level duplication. However, with the LXRAs continued use of elevated cast concrete channels, such as used on the CD9, elevated rail from the up side of Civic Pde, to either up or down sides of Westona station would overcome this space limitation. Civic Pde, Millers Rd, Pier St and Grieve Pde crossings would all be removed as a result and, depending on how warranted replacing the, relatively, recent station at Westona is, Maidstone St could be included if the elevated track extended to the down side of Westona.
Duplicating the remaining lengths of line would then be a, relatively, simple task.
This could be a follow on project after completion of the Cranbourne/Clyde and Hurstbridge duplications, which, considering the increasing number of references to the fact that Melbourne has far more single line sections than a modern rail network should have to maintain timetables, would mean one less single line section.
Any comments or ideas to improve this?
