Construction Progress Southern Sydney Freight Line 2009-13

Overall it works pretty well and its a surprisingly quick trip . Would be a blast on the X with potentially higher speed boards though don't see that happening except with diversions . It feels strange at first not seeing too many signals and thats not such a bad thing . Speed wise its very good aside from two points . The crab across the flyover is really a bit tight and I think the designers tried too hard to reduce the gradients to a minimum and the compromise is the actual crossover point . A bit steeper and a bit better alignment could have had the speed more like 75 or 80 .

The other questionable thing is the point speeds into the loop at Leightonfield , 25 km/h at the western end is plain stupid and to look at the points are good for better . If you don't think so go take a look , it may seem like a minor thing but it will make crosses longer time wise and that has a say in the lines effective traffic capacity . This is more likely to be a yard than an infrastructure issue .

The east end turnout at Leightonfield is completely new and surely could have been made a higher speed.

The west end turnout may be an existing turnout with life remaining in it, and therefore not amenable to speed upgrade for the time being.

Of course, there may be a rule/regulation/law/practice/standard/requirement that turnout speeds at each end of a loop be the same.

Turnouts without a speed sign default to 25km/h. Maybe it is suitable for a higher speed but they have forgotten to install the higher speed "X" boards?

Nope , 25 boards at the west end and the points are of a newer design than the old museum pieces .

Speaking of forgotten speedboards, the Sydney end turnout at Riverstone looks to be faster than X25, but there is no board authorizing a faster speed, so trains dawdle over it.

Leightonfield loop was originally proposed as a short refuge with access to the yard. Railcorp wanted it lengthened for trains waiting for access to RC lines. As it is only 1370m, those trains that matter (1500/1800m) will stay on the main. In the scheme of things probably not that much of an issue.

P.S. X25 on the signalling diagrams here http://extranet.artc.com.au/docman/DocManFiles/DocTypes/SAFE/Files/2-1821.PDF?678916532

I take it that the SSFL would be the longest piece of rail infrastructure built in NSW for... how many years?!?

"cootanee"


probably since the Sandy Hollow-Ulan-Gulgong line was built in the 1980s?

it's longer than epping-chatswood, longer than dapto-kiama electrification, maldon-dombarton would be longer but wasn't finished...probably something else I've forgotten

Page 6: LAU 060 Glenfield in (a) diagram the loop is shown as 1870m metres long, but below in (d) it shrinks to 1850metres. Where did the 20 metres go?
In General Arrangements it says "A crossing loop and sidings is(sic) provided at Glenfield. Sidings at Glenfield? Not when I last looked at the diagram.

The "sidings" are probably the yet to be build Moorebank Intermodal Hub, as shown in Feb Railway Digest.

I'm betting it's a copy and paste mistake (picked up from Leightonfield text).

There is no siding at Glenfield (where would you fit it) and besides Moorebank is so early into its development anyway (not even at EIA yet).
If anything a 'siding' would be around Casula (the anti SSFL locals will be pleased Wink ) .

I noticed last week, and it was still there yesterday, that a 20kph Caution board has popped up between Cabramatta and Warick Farm on the SSFL. Is it a geometery defect or drainage issue ?

Just to point out, shouldn't the name of this thread/forum change now the SSFL is complete and operational? Just a thought......

I reckon this one should be open until they finish off Minto and Lumeah stations Rolling EyesLaughing

The siding would refer to the "Passing Loop" at Glenfield on the Flyovers.

For introduction of a longer section of additional track construction like the SSFL you'd have to go all the way back to ... November 2012.

(Though admittedly it was staged into two smaller bits, and there may still yet be a third stage...)

The 20 kph speed board is due to bogholes appearing, only after 2 months of operation.
So far 4 bogholes have appeared.

Well, I'll be boggered. Bad habits working their way northwards. Hope they are not doing the NSFL

That project was commenced after the SSFL kicked off. And yes another non NSW Guvmnt project Wink
