Two passing loops to cut train delays on the western rail line
For Rydal loop, see: http://www.sa-trackandsignal.net/Pdf%20files/NCRN/JH1460.pdf
For Rydal loop Curves and Grades, see: Not available
* original line 1 in 40 generally
* deviated line 1 in 75
* Ruling Grade Up 1 in 50 Kelso-Raglan Bank
* Ruling Grade Up 1 in 40 Mullion Creek and other places

For Georges Plains loop, see: http://www.sa-trackandsignal.net/Pdf%20files/NCRN/JH1457.pdf
For Georges Plains loop Curves and Grades, see: Not available
* 1 in 100 gradient average to start of Tumulla Bank, proper.
* 1 in 40 down gradient generally

AFAIK the GP loop is located west of GP on 1 in 40 Tumulla Bank, which is undesirable. A better location might be east of GP where ARAIK, the track is fairly level, and allows a run at the steep grade.

Again...another case of having to open the link to find it's the western rail line in NSW of all places.

I live on the western rail line...in Victoria.

No. Expect completion and official opening in the month before the state election.

It is likely that there is no perfect place to locate a loop. They all come with compromises of some sort. The loop at Georges Plains appears to start on level ground at the eastern end and finish on a 1 in 75 approx, which should present no problems for trains that have dealt with the 1 in 33s over the blue mountains. It may not be the best place to stop, in the up direction, but if you can stop in the refuge at Lawson, it should be apiecea cake.

A higher speed turnout at the end of double track sections would also be desirable at
* Wallerawang
** single line
* Tarana
* Kelso
** single line
* Newbridge
* Murrabo
** single line
* Springhill
* Orange East Fork

A higher speed turnout at the end of double track would also be desirable at Newbridge and at Tarana, etc., would also be nice.

Tarana has a 50k turnout which is probably adequate considering the speedboards in the area but Newbridge was completely botched when the line was rationalized. As you say, a high speed turnout on the city side of Newbridge would have made much more sense. Considering the cost of trackwork, I imagine we are stuck with what we have.

Turnouts have a limited lifespan, and when due for renewal that would be a good time to replace them with higher speed ones.

Ideally signals and blockjoints should have already been positioned to suit the future upgraded turnouts. Ain't rocket science.

The new loops are to be  1800m long, which is the same as the long loops all the way to Perth. Forward thinking, indeed.

Freight traffic from Perth doesn't come in to sydney via the blue mountains any more. 2 separate networks with the line to dubbo being under the NSW CRN and traffic from perth taking the ARTC route via Cootamundra.

Not to say the 1800m loops aren't needed but that they would be for the growing freight traffic to/from Dubbo and Orange and not interstate traffic from Adelaide and Perth.

There are still a lot of crossing loops between Lithgow and Crystal Brook that are only about 900m (half of  1800m).

Such as Polona.

Not to mention longer loops allow faster crosses for shorter trains, particularly if you are going to be there for a double...

What is this growing freight traffic from Orange of which you speak?

Fletchers is looking to expand in the future and I understand there are plans for an intermodal in orange as well. Fletchers might even pick up on it's way through. I'm sure I heard something about a new intermodal at orange. I am searching for that info.

Only indirectly related to the main thread, but SSR has started running occasional trips from Dubbo to Hermidale, on the Cobar line, on behalf of Fletchers.

Are 1800m trains even allowed over the mountain? I thought it was only 1500m.

While the two new loops are 1800m long, Polona remains at 900m, or half 1800m.

A bit silly really.

900m is big enough for all the passenger trains and some of the smaller freight.
