We think the heat restrictions are bad here just check out what may occurr overseas. Remember its summer in Australia.
The Sydney Australia V line is talking about putting heat restrictions on freight trains. 38c=100f, 33C=91F

If it's that hot in Victoria I wonder what it's like in the northern states. I've been told Darwin is a sweatbox in summer. Not sure about Brisbane.

You would think the Aussie's would have figured out hot weather railroading long before the US carriers - obviously, in shutting down, they haven't.
Never too old to have a happy childhood!

Please remember the whole CWR performance issue is about rail temperature range. I the rail never gets very cold a higher maximum rail temp can be managed.

I don't think Austraila has the temperature extremes that US carriers experience on an annual basis. Along BNSF's Northern Trans-con, I suspect the normal temperature range is -30 to +100+. I don't know the specifics of BNSF's weather restrictions.
My carriers temperature range is about -15 to +100, there are no specific 'cold' restrictions. Heat restrictions when issued are normally in effect between 1300 to 1900 and call for reduced speeds for both passenger and freight. Heat orders can be issued either for expected highs of 90+ or they can also be issued when a increasing temperature change of 30 degrees or more is anticipated. Track inspectors patrol their territories during the hours of restrictions.
Main tracks of all Class 1 US carriers are almost exclusively welded rail (I won't say all because there MIGHT be some small segment that is still jointed rail).
I just had to comment...
Victoria gets mild heat, in the high 30's in the northern parts of the state during summer...
Most of the mainland of Australia has high 30's temperatures during summer and to go past 38 is not uncommon(100f)...
Where I live its regarded as like living in a fridge, but we get 40 c (104)plus temperatures during summer and its nice to have a 16c(60f) temperature during winter...
In the wheatbelt of Western Australia during summer, 40c(104f) plus...
So you can imagine what its like up in the iron ore country where the massive ore trains are... I have been bogged in a creek and digging for most of the day when the temperature was 56c(132f) in the shade... Was only around the corner from Parabardoo mine which carts ore by rail to Karratha...
Darwin is hot but its the humidity that gets you there, the Pilbara, inland, is probably the hottest.. Marble bar holds the record number of hot days and I have had to stop there and change a few truck tyres, not a good job there but the pub had cold beer...Imagine driving a steam engine there, they had one once, the track bed is now the main road going north...
BaltACD...there are no specific 'cold' restrictions.
Cold weather still gives the track inspectors fits. Continuous Welded Rail isn't all continuous...
Nothing like a good pull-apart to slow things down...
Larry Resident Microferroequinologist (at least at my house) Everyone goes home; Safety begins with you My Opinion. Standard Disclaimers Apply. No Expiration Date Come ride the rails with me! There's one thing about humility - the moment you think you've got it, you've lost it...
Baltcad, We have large temp changes in central Australia, over night... Can be 38c(100f) during the day and -2c(28f) at night...
Our high temperatures during summer, are in the high 30c(90f) up into the mid 40c(104f).. These temperatures are continuous during summer and inland from the coast, it can get so hot the roads melt...
As victoria, who knows what there problem is but the railroads have only just started this yet the tracks have been there for a 100 years, maybe there scared they might not be able to afford the cost of air conditioning...

csxns wraithe who knows what there problem is but the railroads have only just started this Wonder if the road trains can handle the slack.

Not in Victoria... They dont allow roadtrains..
When they closed the tier 3 lines in WA, we where flat out... Some 800 roadtrains came here from the East just to keep up with the work from harvest, now that the drought in the east has ended what next, they've gone home...
Problem with having lots of trucks here is the roads are no longer built to high standards so when your going down the road the bitumen heats up and melts, the next thing you have to do is clean it off... Try cleaning it off of the guards and sides of the trailers and cab... Its not fun..
Keep in mind, the stuff we use carting grain, maybe small compared to up north, but we cart upto 100 tonnes gross on 2 trailers tri-tri-tri-tri combination down to 83 tonne for bogie-tri-bogie-tri, so wheel weights are high and all within 27.5 metres in length... Mind you, most dont realise outside of WA, we actually travel into the city with these weights...
Personal experience here, retired truck driver...
