Any HSR or MSR train to Sydney must run to the city and not just Paramatta, while people can always change trains as soon as you do this you will kill alot of boarding's. However it won't be doing 300km/hr to the CBD or through the burbs.
I've stated my prefered option above a few times, improved alignment Campbelltown to Goulburn and then to ??? (name escapes me, station nth of Canberra not Targo) north of Canberra and new alignment to Canberra Airport.
- Campbelltown to Canberra should be 2hr tops.
- Improved alignment also benefits all other users.
- Train technology is MSR which still enables the use of the current line side signally system although it would need to be improved and the bi-directional.
- I would also have frequent high speed crossovers to enable easy passing.
(Germany I'm sure will have very limited access by freights on HSR tracks where they are actually rated to HSR and the freights won't be 23t/axle 1800m long monsters like here)
I know some want it to go via Straithfield, but this will only slow it down and there are also capacity issues, perhaps some services may do this. There would need to be significant track capacity and alignment improvements on Western Main.
Sydney Terminal yard I've stated before is a dogs breakfast.
- This needs to be rebuilt at significant cost to a bi-level arrival departures to eliminate conflicting moves and increase capacity to 20t/hr and thus enable capacity for MSR services to arrive without taking 4min to run from Redfern.
I would propose most MSR from the south arrive via East Hills,
- Extending the Quad from Revesbey to Glenfield and on to Macurthur, the new quad tracks to be built for 160km/hr running.
- Complete the Six tracking through St Peters etc and remove the incomplete platforms to improve the alignment.
- to get the extra capacity and speed on East Hills Line, tunnel 15km Sydnam to Revesby (or potentially closer) to enable +120km/hr. This route can also be used by Melbourne and Southern highlands and South West express Commuter services + trains from new BC airport running via Mascot to the City and solves the biggest obstacle for Southern highlands from running more frequently. this tunnel would probably cost about $2-3B in its own right, but look at the benefits to so many users. It probably negates any reason to go via Straithfield as it will be quicker to get to the city and head back.
- I would propose a stop at Glenfield to enable access to the BC and the Y link to Paramatta and the West/NW.
Back to the airlines
- I doubt the Singapore flight will have too much impact on QF/VA Canberra to Sydney, Sydney to Singapore is barely 10% of the domestic route and I'd dare say Sydney and others from elsewhere make up the bulk of the users.
- The above rail proposal will not delay in anyway the BC airport, but I would expect it to take up to 500,000pa off the air route and more off the road and probably double Southern Highlands commuters on rail and thus justifying its existence and expense.
- It can be built over 5 years and have services progressively increased as people jump on the bandwagon with each new section coming on line
- I in no means propose that it would be cash flow positive, but would benefit the community overall.
- the XPT can contiunue to run to Melbourne, but it will save around 60-90min per trip as a result of above, thus increasing slightly its support and reduction of running costs.
- The XPL would sustain the CBR service, increasing frequency as track upgrades allow, but eventually new trains would replace and the XPL diverted to Southern Highlands to cater for expected growth.
