In keeping with RP’s reputation for minutiae, will the platforms at Oakleigh be re-numbered, and if so, how?
Option 1: Keep the same numbers.
The least expensive. This will cause considerable confusion in later years, eg “Why is there no Platform 1 at Oakleigh?” and raise numerous concurrent RP threads on the subject.
Option 2: Renumber Platform 3 as Platform 1
The minimum cost renumbering option, however this would be the opposite of the numbering pattern on the stations on either side, where Platform 1 is on the south side.
Option 3: Renumber Platform 2 as Platform 1 and Platform 3 as Platform 2
The most expensive and will cause some initial confusion but conforms with the pattern at other stations on the line.
