Phase 3 timetables

[somebody]

With the likely introduction of the Kippa-Ring line before CRR is done, I am thinking about how to improve capacity to cater for the passengers.

I think the best plan is:
Partially or fully duplicate Doomben to allow for 4tph
All stop the Airport trains
Coordinate above services for a 6-9 minute frequency at Albion and Wooloowin between them
Express Shorncliffe trains between Bowen Hills and Eagle Junction running at 4tph
All Caboolture/Petrie/Nambour trains to non stop Albion, Woolowin, Toombul and Nundah.
Gympie North trains to go to either use the same pattern (i.e. serve Northgate and Eagle Junction) or go to an earlier arrival in the AM when frequency doesn't need to be as high on other services.

The main part of this which cannot be done now is the Doomben upgrade, but the Airtrain change would require difficult negotiations.
A second best option which can be achieved on current infrastructure, easily in the PM peak, is to have the Nambour trains all stop to Eagle Junction at 2tph combining with the Doomben trains for a 15 minute frequency, and this combination needs to coordinate with either the Shorncliffe trains or Airport trains to have a 6-9 minute frequency at Albion and Wooloowin.  At least that frees the Caboolture/Nambour trains from serving those stations.  Nundah and Toombul may be more controversial, particularly if the all stopping airport trains in peak cannot be negotiated.  I would argue that it still should be done however.

Someone has already voted "no".  Love to know your plan for allowing for Kippa-Ring pre CRR!

[Derwan]

Are you proposing to run the Shorncliffe, Doomben and Airtrain services on the suburbans?

[Stillwater]

Earlier arrival in the AM of the Gympie North train?  It sets out on its journey at 5.56am.  Should people forego dessert the night before to run for the train now!

Do not know what your no voter had in mind but in a practical sense Kippa Ring is not a practical option without CRR and the additional trackage between Lawnton and Petrie.

AFAIK Lawnton to Petrie is part of the scope of the MBRL.  It doesn't make sense without it.

[ozbob]

will invest approximately $165 million to build a third track between Lawnton and Petrie, which is already provided for in the South East Queensland Infrastructure Plan and Program.

It is expected that the Moreton Bay Rail Link will add 4 services an hour during peak times to the existing QR network. Due to operational constraints between Petrie and Lawnton, a 3rd track will be required. There is a risk of constraints within the Brisbane inner city rail capacity delaying or limiting new services along the Moreton Bay Rail Link.

Not sure when this scheduled though ..

And Ferny Grove.  So Yes.

Appropriate timetabling isn't that hard.

8tph Ferny Grove, 4tph Doomben+Airport+Shornclife = 20tph. Well below capacity of 23-25tph.

Earlier arrival in the AM of the Gympie North train?  It sets out on its journey at 5.56am.  Should people forego dessert the night before to run for the train now!   

Whatever it takes.

I for one have used a train from Newcastle to get an early flight.  I boarded at Epping at around 4:30am.  Must have left around 2am.

I say it is practical and achievable! Something I wouldn't say about Sydney's NWRL.  Not only that, but both also seem likely to happen.

AFAIK Lawnton to Petrie is part of the scope of the MBRL.  It doesn't make sense without it.

Same comment as above, but I would add that a bridge to allow for triplication makes no sense.  If we are to bridge the river, we need to allow for quadding.

Ozbob, wrote replies as I was reading.  Don't have anything further to add.

It is possible to have the MBRL before CRR.

Just terminate the train at the first mainline station it touches and transfer passengers over.

Which makes absolutely no sense because the trains are supposed to be full as at 2016 - what do they transfer over to? Another Caboolture service?  By putting those on, you'll only get full trains by Burpengary or earlier.

Slots should be allocated between Caboolture services.  The line is not at utter capacity, even in peak.

Indeed it makes no sense.  I continue to argue that 20tph through Virginia is an adequate capacity, even post Kippa-Ring.

[somebody]

I see that limited stop Shorncliffe isn't widely supported.

Very interested in what you will tell people at Nundah and Toombul, if their peak service is reduced to 4tph.  I'd also be interested in the loadings of such a service.  Likely to be quite awful.

[Golliwog]

So your sweetener for Nundah/Toombul was their frequency will drop to 4tph but by running the Shorncliffe trains express Eagle Junction-Bowen Hills they'll get a faster trip? Didn't we point out elsewhere that the Airport trains which currently do that don't do it any faster than an all stops trains? I'd also argue that even though you've only proposed 20tph out of a possible ~24tph you're limiting capacity by not running the same pattern, so the theoretical maximum capacity of 24 wouldn't be possible.

There is no excuse for this.

Incorrect.  A number of the trains on the suburbans head to/from the Ferny Grove line.  By coordinating the "shadowing" effect with these trains no capacity is lost.
