It’s arguably the most painful thing about TfNSW. We’re actually really good at creating good locations for interchanges, but terrible at providing sufficient links into those interchanges to make them work optimally. Seriously, the layout of Sydney is tsuch that it should be a layup, but it’s not, somehow. Major centres also happening to line up with major shopping and business areas. Suburban hubs located in ideal spots for interchanges despite the topography, and still they manage to screw it up.Preferring feeder buses to park+ride is normally a hill I'd die on too, but one has to be practical also. This is not PTA WA and Perth with its excellent feeder bus system. TfNSW's skills in bus service planning and operation (the latter limited also by Treasury funding) are terrible and, like light rail, their skills don't look like improving any time soon. Meanwhile there's a big demand for the metro from westward, but no way to get on a train unless they arrive at the station before 7 to get a park. There is just one bus from Windsor that runs a few trips a day on weekdays only. No direct buses to and from anywhere west of Windsor. This means those people keep driving. The metro has plenty of latent demand that's constricted by inability to access a station.
And why should there be a limit on the length of a train line? I haven't mearsured the full Bankstown-Macarthur length but I don't imagine it's longer than the Mandurah-Butler line (and certainly not than when that's extended to Yanchep), which has trains running end to end, typically on-time. Cutting the Sydney circular line (if I can call it that) at Schofields makes as much sense as cutting the Perth north-south line at, say, Cockburn Central where a new line is joining in a few years. A lot of inconvenience for commuters. The reason does seem ideological - scoping for a different operator, but that's a very poor reason to bugger it up. It's best if the whole line is under one operator. Let them get different operators for other, independent, metro lines.
I’ve pretty much reached the conclusion that the only solve is sacking basically the whole department and getting in fresh blood that can look at the problems differently. The whole department is stuck in its old ways, and can’t get out of its old thinking of car is king, the transport’s for the poors.
