The original Tulloch built double deck carriages were built to provide greater passenger capacity in a train which could use the existing city platforms. Expansion of the Sydney suburban area meant that commuters would need to travel well beyond the previous electrified lines which ended at Sutherland, Liverpool, Parramatta and Hornsby. The aim was to provide more seats for the longer distance commuters and to leave the single deck trains

for city and short distance commuters.

It's a flat junction at Lidcome with some back tracks pointed east at Flemington so that they don't have to join the main lines straight away, so it's pretty bare of conflicting traffic that might interfere with movements. At events where they're coming and going they only load from one side of the train, unload from the other. I don't know whether they have procedures for loading/unloading from both sides when all traffic is one way.

In all my years of experience riding Sydney deckers, I observe that standees are extremely reluctant to populate the decks in the gondola. They will do so when forced by sheer numbers but spread out pretty loosely if they can.. One problem is that there's nowhere to hold on properly, another is that people block the stairs by sitting or standing on them. They're really designed as sitting trains with provision for standing at the ends, not the full quid. There's a discrepancy between theory and practice with these trains..

It could be asked whether there was in fact a bit of spin and lies back in the 60s when the idea of deckers was put forward as a "solution", I recall the idea was a relatively temporary solution until all those proposed new lines and track augmentations were built.

I agree about managements and Ministers, but don't worry, I do my own calculating. We could argue this till blue in the face, at least its electric traction unlike Vera who may attract the attention of the mod ;)

I am not quoting theory, I am quoting field measurement. For a unidirectional flow from Olympic Park, both-side loading is achievable, as nobody is alighting. Likewise, from the very diagram which Tony cited, on 2 min track headways, a train can have a 3 min platform headway, and back to a quite achievable 60 000 per hour.
Can trains peel alternately left and right grade separated when approaching Flemington/Lidcombe, or is that a flat junction?

The French carriages, which have three doors per side, are also substantially longer. Recall, the original Sydney design made provision for a single-leaf door as well as a double-leaf one in all vestibules.
At all times, railway capacity in Sydney and Melbourne has been stifled by useless managements feeding gullible politicians, but transport hobbyists shouldn't fall for the spin and the lies.
