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.

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

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.

sulzer is a totally different profile and i do not pretend to be someone i am not. my real name is heath and sulzer is someone else with bad punctuation!!!

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.

does the apamurra grain get trucked to monarto south for railing to adelaide?

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.

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?

is 60,000 tonnes a lot in grain standards?

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

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

Correct

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?

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.

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)?
