I was just thinking about improving frequencies on routes. I know that when CRR is online, the line pairings are going to be Ipswich all day express to Brisbane Airport (I’m assuming 15-30 minutes), Springfield Central to Shorncliffe (15 minutes) and Doomben to Indooroopilly.
I was wondering would it be possible to reliably run the Doomben services to Darra instead of Indooroopilly? I noticed there’s a track crossover near the station, but 7.5 minute headways are also pretty tight (that’s also assuming that Doomben is given minor improvements to run 15 minute frequencies).
So, all that to say, is this possible?

I think Doomben needs a bit more than “minor improvements” to be able to run 15 minute frequencies.

Maybe so. My main question though is would it be feasible from Darra?
Another option for the northside is to run 15 minute headways from Springfield Central to Shorncliffe and 15 minute headways from Darra (if that’s feasible) to Northgate, giving that whole corridor true turn up and go frequencies. I have read that Nundah is earmarked for additional high rises, and Toombul has potential as well with the old shopping centre redevelopment.
Anyhow, still begs the question does Darra work for this?
Regarding what you said about Doomben, then perhaps Doomben could be at the current 30 minute frequencies and run Doomben to Roma Street, terminating at platform 7. The current track configuration from what I can see would allow this, and with much fewer trains running through South Bank and using that track pair there would be plenty of capacity for this.
That would then support the high frequency spine from Darra to Northgate.
Another thought I had regarding high frequency routes is that it looks as if post CRR they’re going to run shuttles from Boggo Road to Bowen Hills to supplement Cleveland - Ferny Grove services.
I think they should extend those shuttle services (assuming it can be supported logistically) from Cannon Hill - Mitchelton. That would give this line pairing the following frequencies:
Cannon Hill - Mitchelton: 7.5 minute headways
Cleveland/Manly - Ferny Grove: 30 minute headways (from Cleveland), 15 minute headways from Manly.
This would allow very high frequency services from a significant number of stations, and most of the remaining 15 minute frequencies. I believe this would help start to drive changing travel habits for more people.

This is a great thread and an important thing to focus on ahead of CRR opening.
As a “demand”, all-day high frequencies is a simple but compelling thing to mobilize public opinion around.

Thanks. I can’t do much myself, but my hope is that with any discussion that results, that any powers that be might see these ideas and implement them…
