Monarto South To Appamurra

Has it occured to you the signals may be LEDs - a long life and low current consumption?   Most traffic lights are LEDs and are quite bright - a few older incandesant types are around and these are usually dimmer and can be hard to see.

I concur with justapassenger: it is entirely appropriate to use capitals and it actually makes what you are saying easier to read.

Has anyone been along this branch recently?   What state is it in?   I might next week.

Got a mate who's passing through that neck of the woods on Monday, will get him to take a few photos when he gets back. I haven't been up that way for yonks, but it did look a pretty tired old branch off, some bits completely grown over, as to be expected. Also remember seeing a fair amount of graffiti at certain areas (also to be expected).

God damn graffiti "artists", little ***** should be forced to clean the stuff themselves!!

if the line has not been used since 2006 how can that globe last for 6 years.

Question, is that the same globe that was there when the line closed? One would assume an signal electrician would change the globe when it blows.

well i went to monarto zoo on a family outing and i stopped to check the apamurra turnout and the mainline protector signal was bright red!!! (the one on the apamurra line just before it joins the main line) if the line has not been used since 2006 how can that globe last for 6 years.

That's nothing, somewhere in America is a light bulb that has been working since 1901

So two things from that article:
1. You can make light bulbs that last a long time, probably with higher cost to make. I'd think railways would buy quality lights to start with.
2. Switching it on and off shortens its life. Unless the signalling has lost power due to a fault, the apamurra signal would have been on the entire 6 years.

Back to Heath's question
The Junction at Monarto South is still active and hence the signal is there to protect it.
Because it's an active junction, it's maintained as such, even if it isn't used.

Same goes for the junction to NRM at the Port, it's still an active junction and is maintained to be used.

Another place this has occured is the short spur that was until recently the southern end of the BG Goal loop.
The red signal has been alight all the time !  (the spur has been used to stable track machines I believe)

Light globes ..... as someone has mentioned, a light globe's life is reduced everytime it is cycled on and off
If it is left energised you'd be amazed how long they can last.

Is it still the case that the Appamurra branch up to the level crossing can be used as a refuge if rail traffic conditions demand it?

The lengthened loop at Monarto South would further alleviate the need to use the branch as a refuge.

Do grain trains still stop there?

I recall the signal head in question is a searchlight type for which the lamp only goes out when the lamp burns our or the battery goes flat.

That said, some searchlight signals are approach lit, I think those on the Dry Creek Crystal Brook line are, although not all now.

well who maintains the signal at port dock and on the rosewater line?
and does the apamurra grain get trucked to monarto south for railing to adelaide?

what happens to the grain in the apamurra silos and where does it get transported to? what are the tonnages at the moment?
  alcoworldseries Deputy Commissioner

Location: Auburn
Most grain from Appamura goes by road to Port Adelaide/Outer Harbour Heath, last tonnage I heard on hand/capacity there was 350,000 tonnes.

hasn't been more than 60,000 tonnes received at Apamurra for some time

is 60,000 tonnes a lot in grain standards?

As to who maintains the signals at Port Dock and on the Rosewater loop try DPTI or whatever they are called, or Adelaide Metro. The same goes for the track too. As Pressman has stated the signal at Port Dock is still an active signal guarding the mainline here. The NRM do get Adelaide Metro trains in and out of the NRM at times, so the driver of these movements needs to know when it is safe to move past this point out onto the mainline to get back to Adelaide. They are all maintained by DPTI/Adelaide Metro electrical and signal fitters.

"Heath Loxton"


Primary Industries SA estimate the 2012/13 SA grain harvest will return 6.69 million tonnes from 3.99 million Hectares, which they describe as near the long term average crop level.
By the way, that equates to 4.15 tonnes per acre.

60,000 Tonnes is about 0.89% of the states total crop, so it is nowhere near a lot

so there is not enough grain in those silos to warrant a train to apamurra?

More completely, there was not enough to pay for the cost of keeping the infrastructure maintained over the rest of the year when there were no grain trains. If there was other traffic using the line or a much larger amount shipped each year (i.e. from a larger catchment) then there would have been a case for keeping it open - like the Karoonda and Pinnaroo lines which are used only for grain but still just manage to survive because they have a much larger amount of grain each year.

The extremely loopy nature of the route from Apamurra to Port Adelaide (roughly 60 km longer than by road) doesn't count in favour of rail to that area, and it only gets worse for the original full length to Cambrai and Sedan. That route was doomed as soon as trucks developed to the point of being able to reliably haul cargo over the plateau between there and the Adelaide plains.

so how much grain could the karoonda and the loxton silos combined hold to warrant seasonal grain trains and has or can the appamurra branch up to or slightly beyond the level crossing be used as a train refuge for grain trains or storing empty hoppers during grain loading as to not block the monarto south loop?

From my observation of the line today it would cost more than the potential revenue to get the somewhat overgrown line back to the situation it was when trains were allowed the lightning fast speed of 20kph on it.

well what i said was: is the line used to store hoppers for the monarto south silos during loading or for refuge of carriages or trains or to store track machines?
(as far as the level crossing)?

It was available in SAR days to refuge trains which could proceed at low speed to the crossing.

Just how long this arrangement lasted into AN days I don't know, nor just how often it was used in practice even in SAR days, but I assume that when ANR was sold in 1997 and the line came under the control of ASR (now GWA) and the main line under the control of ARTC then any such arrangement ceased.

From observation nothing has used the line for some time.
