Why isnt there a triangle at Merrygoen

 
  MD Chief Commissioner

Location: Canbera
Just as a mindless exercise I worked out the differance in distance for trains running from Brisbane
to Adelaide or Perth, by running via the Farley triangle at Maitland, and via Gulgong,Merrygoen,Dubbo
and Narromine to Goobang Junction,instead of via Cootamundra and Stockinbingal.
The differance is 210 km in favor of Merrygoen.
I can only assume they dont go that way because of the difficulty in reversing at Merrygoen.
Avoids having to run thru Sydney and also avoids the 1:40 grades up the Cowan bank.
23 tonne axle load locos are allowed all the way, albeit at 60 KMH from Gulgong to Dubbo.

Train needs to be reversed also at goobang.
The track between Dubbo and Gulgong is not the best with many 40km/h limits on it.
Length of crossing loops.
Coal traffic from Gulgong to Maitland.
Track grades especially out of Dubbo

Some of the reasons maybe why not.

Can't cash in on Sydney Adelaide or Sydney Brisbane traffic either . The turn around at Merrygoen for trains longer than the loop involves having a crew there and a set of exchange engines .
Going the back way is mainly used when there is track work on the usual route .
The reason why there is a missing link at Merrygoen is because there is no political will to pay for it , how long did it take to make Parkes/Goobang a triangle junction to the south - towards Forbes .

Construction of a triangle at Merrygoen isn’t as straightforward as you may think.
There are issues with gradients on the approach lines. This pic illustrates it:

I believe other options such as a balloon loop at the northern end of town have also been considered.
Existing traffic might not justify the cost of works required.

Hi guys been reading your post I think there is a rail corridor between Gulgong and Wellington I travelled between the 2 towns and some of the corridor is close to the road not sure if it was complete someone in NSW would have some info on this Paul

On reflection theres another possibility as well.
Whats ARTCs main function?
Is it to maximise revenue from track access charges, or to provide track access at the lowest possible cost to the rail operators?
The current arrangement generates more revenue as its requires more NTKs for trains running from Brisbane to Goobang Jnct.
One of the fundamental problems with Horizontal Integration.

Heres another question.
For trains like BM3 going from Brisbane to Melbourne , how many sets of track access charges are paid.

Yes, that Gulgong to Maryville line should've been completed. In that link, and the maps, you can see where this rail line was going to go.

Also to add, there is not enough traffic demand to pay for any upgrades. I am sure if a coal mine or similar was found anywhere of the direction Troy Junction things would change.

.... I think there is a rail corridor between Gulgong and Wellington ....

Was.
The majority, if not all of the right-of-way was removed. (Part of it goes through a neighbours property). It is not a viable option for some to satisfy some disjointed freight that may go from QLD to SA, especially when the Fed's keep raising the inland route every now and then and then can that idea...again.

One day, when the coal price may drop or the rest of the world really demands our coal and minerals, is when we may see these lines constructed, updated and used.

Mind you, there's a lot of freight moving by road these days because there is no direct rail alternative. Chicken and the egg, I know, but the market has decided modern day freight routings and if there isn't a railway line along that corridor, then the market won't use rail. There is a lot of freight moving south of Brisbane to Victoria, South Australia and even Western Australia that gains nothing from sitting in Sydney for a day and chooses road for that reason. And if nothing else, the Cobbora coal mine was approved east of Dubbo a few weeks ago...maybe that'll change the junction at Gulgong at least...if not Merrygoen.

Actually, it has no affect. Cobbara Mine does not require any changes at Gulgong. The new balloon line into the mine has already been pegged out for sometime ready to be constructed and will enter the current line at Tallawang. It has no affect for Merrygoen as the coal goes east.

The line has been pegged out for about a year or so, but there is no movement on construction as this State government who are still the majority owners, are not prepared to rush on this development. Originally the previous government had planned the coal would supply Earing Energy with coal, but the current Government has terminated that deal and state that even after approvals it maybe 4 years before anything will happen, and only if they can sell or lease the final stage.
