In case you haven't noticed, I am not thinking about what
, but why
Remember that both Brisbane and Sydney Airport charge a premium fare. I cannot say for sure whether this has a direct impact on patronage, but I am fairly certain it does. I also note Brisbane's Airtrain frequency is 30 minutes during off-peak - definitely not enough to get a decent usage.
Oh, and there is plenty of evidence out there to suggest a good frequency public transport service can reduce traffic volumes.
If I really wanted to, I could write a full essay on this. It is not hard to conduct further research.EDIT:
Oh, and I never said we needed the rail link now.
