Core Frequent Network: Beenleigh Line Train Upgrade Zone

Manly TUZ not Cleveland TUZ  too much single track etc.

[#Metro]

We can also achieve 4tph Petrie to Richlands and 4tph Ipswich to Caboolture, and these TUZ's can be added to the CFN.

How does this work? Will there be express on one of them?

We can also achieve 4tph Petrie to Richlands and 4tph Ipswich to Caboolture, and these TUZ's can be added to the CFN.

How will the Nambour expresses, traveltrains, freights, maintenance trains, etc etc going to fit in.  The better alternative is extend 1 of the 4 Ipswich to Caboolture express is to have 1 of those trains as a Rosewood to Nambour express.  Precision crosses at Beerwah (Currently the existing scheduled cross in the current Sunshine Coast timetables) and another point north of Landsborough is going to be required (hence moving the platforms north of Landsborough to their proposed sites, effectively making new long passing loops).  

Another suggestion to put on top, bringing forth the duplication of the Beerwah-Glasshouse section would effectively remove a cross if timetabled correctly and create basically a long passing loop.

Or the more realistic option without all the infrastructure works, selected services are Ipswich-Nambour and vice-versa on the current 90 minute off-peak headways north of Caboolture, with Rosewood retaining the shuttle service. This would require careful scheduling of IMUs as toilets will be required, or NGR rollingstock are to be provided toilets regardless.

Having 2tph Caboolture-Ipswich exp Northgate-Petrie/exp Indro-Darra and 4tph to Kippa Ring-Springfield all stations would be more realistic than 4tph to both destinations.

Having 2tph Caboolture-Ipswich exp Northgate-Petrie/exp Indro-Darra and 4tph to Kippa Ring-Springfield all stations would be more realistic than 4tph to both destinations.

That would still be worth pursuing, I agree, and is a substantial improvement over the current set-up.

15min to Ipswich and Caboolture should still be achievable though.

Interesting concept here.

I think the critical issue in the plan X vs plan Y is can the trains to the Airport be increased?

Plan X:
4tph Coopers Plains-FYG
2tph BNH express

Plan Y:
4tph BNH-FYG

[SurfRail]

If necessary it doesn't have to be even 15 minute frequency out of the airport.  It would be less important there than at local destinations.

Fortunately the only constraint is International to the up and down subs, as Intl to Domestic is duplicated.

I wonder the cost to duplicate the whole thing?  It's all elevated and the pylons are all in place, so can't be that much.  The Airport Link contracts presumably do not have Sydney/Melbourne style restraint of trade type clauses which would prohibit that investment being made by the govt while the road concession is operating.

Most of the pilons are only there for the current single track. As far as I can see, there was no future-provisioning to make duplication quick and easy by having 2-track wide supports along the single track section.

[SurfRail]

The corridor is there at least, or wouldn't need too much extra.  No costly tunnelling or excavation, just bung the poles in (and build a station at Airport Drive for good measure).

[#Metro]

I think the Airport is the least of our concerns. There are many ways to get to the Airport, not so many ways to get to other places on the rail network.

The Rail Service and Infrastructure Report produced in 2007 by Systemwide for TransLink, showed a planned 4tph off-peak service as far out as Robina.

• 2tph Kuraby all stations - dep '01, '31 (other services stop at '15, '27' '45, '57)
• 2tph Beenleigh all stations - dep '20, '50
• 2tph Robina express from Kuraby - dep '03, '33
• 2tph Elanora express from Beenleigh - dep '12, '42

Based on what additional infrastructure - Coomera River duplication, Elanora extension and third track to Kingston wasn't it?

Although it's not made clear in the text, it appears that the mentioned infrastructure projects would probably have been completed before this particular intermediate off-peak scenario. BrizCommuter would be interested to know where these services would have to overtake each other based on the times above.

Sadly, it's now 5 years after this report, and all three of these infrastructure projects have disappeared into the land of the unknown.

What a bizzare, messy plan.

What's wrong with

* All stops to Kuraby or somewhere like Coopers Plains
* Express from Kuraby or somewhere like Coopers Plains to Beenleigh
* Express to Beenleigh then all stops to GC terminus

Does your plan provide at least 4tph to all users as far out as Robina?
The "bizarre, messy plan" provides that.

[#Metro]

Is the above plan possible on current infrastructure? Doubt it.
Fantasy 2031.

2tph Kuraby all stations - dep '01, '31 (other services stop at '15, '27' '45, '57)

A service to Kuraby seems OK

    2tph Beenleigh all stations - dep '20, '50

Stopping all stations - you have got to be kidding!

2tph Robina express from Kuraby - dep '03, '33

Robina Express from Kuraby! This is going to be sooooooo sloooooooow. Significantly slower than the current service. Why bother? I thought improvements were supposed to make us better off, not worse off.

2tph Elanora express from Beenleigh - dep '12, '42

This seems sensible, but half hour frequency, yuck.

K.I.S.S. PLEASE.
