Deep breaths peoples
1) It was a Qld LNP election plenge last year
2) Its been raised numerous times in past as the bridge approaches capacity
3) The issue is the reverse run back to Sydney, the XPT uses the 3rd track which is DG, this is the line the peak flow GC expresses run on. So they are running towards each other on a track with limited passing opportunity due to poor design, hence the XPT's path is not just a few minutes, but about 15-20min of lost operation time. To try and cross using the suburbs would mean crossing the outbound suburbs. The XPT's reliability is also poor and hence very disruptive when departing Brisbane late.
4) Why would it both Fed LNP, Abbott ran a campaign saying suburban rail is a state govt issue
5) While we keep bitching about regional/country rail cut backs, they are not being done as a conspiracy theory. Its happening all over the world in similar demographic and geographic areas. Look at Eastern Europe, since the fall of communism, hundreds of trains have been canned, hundreds of lines closed. As people become more affluent, slow regional trains become less popular and there is a critical mass issue here as well. Not enough uses destroy frequency, low frequency detracts more users. Even a train a day is not that convient. Rural Australia has often been super critical about line closures, but by and large they didn't use the services prior. Western Europe has seen a surge in train usage but only after spending $100B's to upgrade lines to higher and high speed and in a much more dense area than most of Australia even comes close to and at the same time, they serve cities were owning a car can be more trouble than its worth, costly and anything bigger than a Suzuki is unparkable. However travel to those cities and there is still cars, tunnels and bridges and hwy's and super hwys.
Australian regional rail will contract because the people who grew up with rail travel culture and still use it frequently are dying off from age.
Yes there is alot we can do to make it viable, but we want to make a viable well used railway on a route that doesn't even have a four lane road for much of the distance? I think the European's would laugh at the poor economics of this.
