Three-door per side per car is the Melbourne standard. They place more value on dwell time and effective, evenly-distributed loading than Sydney.

Speaking of which I note in John Dunn's Comeng history that he was commissioned to design a double decker suburban train for Melbourne in 1998. For the above reasons (and, as he admitted, because it had to operate amongst existing three-door stock which it couldn't cause delay to) it had three doors and resembled the French RER double deckers. The cars were about 5 metres longer than Sydney cars but had less seats. It didn't proceed because of the costs of manufacturing a specialised design in an environment where the local industry was collapsing and numerous standard off-the-shelf single deck designs were available from overseas companies.

I note that John did his capacity calcs at 6 ppsm which may explain some of the over-optimistic, non real-world capacity claims for double deckers!
