Turns out if you park stuff for a couple years and don't do maintenance it might develop some problems. Who knew!?
Winter is coming once again out here, they are forecasting snow within the next week.

No mention of a cleaning bill for the crew's underwear. Extreme Stress.
I know Canada's regulations differ than ours - but no initial air test? I mean half of the brakes not working? Yeesh.
It's been fun. But it isn't much fun anymore. Signing off for now.

The last paragraph (emphasis mine): "Given the potential consequences of a loss of braking function due to brake valve failure, Transport Canada may wish to alert railways and car owners of the need to examine the brake valve functionality of cars that have been in long term storage, particularly if the cars are to be used in cold weather service."
MAY wish to alert railways?!?!?!?!?

No initial terminal brake test shocked the s..t out of me. Especially when traversing territory with 3% grades.

Safety culture or the lack thereof?
Does the word "may" have a more demanding connotation in Canadian English than in USA English?
Need the Dude to weigh in and clarify... maybe cx500 as well.

The TSB is only allowed to make recommendations, and does not have the power to enact legislation or regulations.

The train would have undergone a No. 1 air brake test by the car department at the yard where it originated, most likely Prince George, BC in this case. Having received a No. 1 air test no additional tests would be required unless the equipment was left off air for longer than 24 hours.
By rule, the crew would have had to perform a continuity test after running around the train (this mine does not have a loop), nothing more. Any additional air test involving a walking inspection of the train could be construed as deliberately delaying the train.
Unit coal trains in CN's Western Canada service normally undergo a No. 1 test when the empty train arrives in Kamloops or Prince George, and this test is good for the rest of the train's cycle (unless of course it is left off air for over 24 hours).
Are unit coal trains in the U.S. required to undergo a air brake test after loading at a mine?

Soudns like these cars had major prblems that should have been caught before this ill-fated run.

Yep.
Those No. 1 air tests are quite often done by a guy on a ATV zooming up and down the tracks. The Carmen are under a huge amount of pressure to hurry up and release trains to clear out the yard faster. When you are hurrying stuff gets missed. It's not right but it continues to happen.
I am surprised that after 21 months in storage the cars were not required to go through more thorough testing, such as a full COTS inspection.
More recently I heard of another occurrence that can only be described as a very near miss. The crew of a 60 car limestone train (also on the Alberta Coal Branch) reported that it was not braking properly, requiring much heavier applications to control. That trainset was examined in Edmonton, and among other things eight (8) cars were found cut out. That is over 13% of your braking ability disabled. And this was not reported on the No. 1 brake status report the original crew received.
None of the crews who handled that train reported cutting any cars out, and the Carmen who tested it claimed that every car applied normally. CN management decided that vandals must have cut the cars out, and the investigation ended there.
No one really believes that vandals cut out 8 cars in 8 different places throughout the train, but it was a convenient excuse to shift away blame.
I spoke with a couple friends from the Coal Branch, and crews are now required to perform a brake test and walking inspection of the train prior to departing the mine at Luscar. Any cars that do not set up are to be reported to the Mechanical Department and the train must not depart the mine unless 95% of the cars have operative brakes. If the train does not meet this standard retainers are to be set on cars that leak off.

And nothing derailed. Which I find more amazing than anything the report identifies.
". Any cars that do not set up are to be reported to the Mechanical Department and the train must not depart the mine unless 95% of the cars have operative brakes. If the train does not meet this standard retainers are to be set on cars that leak off."
Depending on what causes the brakes to leak off, retainers may not be able to have any effect.
I went back and worked this line again for a while last year. After this runaway it gradually became required to do a No. 1A air brake test and walking inspection of the train before departing each mine.
The results were quite eye-opening and rather depressing. Nearly every train had at least a few cars that would not hold their air brake application in cold weather, a good number of them never set up at all. Still others were already cut out and not reported on the train journal or brake status report. And the defective cars would return in the same condition even after we reported them to the mechanical department. One memorable car was reported seven (7) times before finally being fixed, or it may simply have been placed in service to a different mine.
Different types of cars had different failure rates, with older cars having more problems (not a surprise). The best cars were the leased CEFX 600000 series, while the worst were CN's own cars and the FLCX 98000 series.
In the interests of both safety and saving time we switched to moderately applying a handbrake on each defective car if the 95% operative brake threshold was not met. As Mark said, sometimes the retainer would hold the air brake application, sometimes it would not.
I'm disappointed that the report does not mention all the air brake problems that continued to occur even after this runaway. I am also disappointed that the 2008 runaway that also got up to over 50 mph on this grade was not mentioned either.
Teck's Cardinal River mine has since closed, with their last train running about a month ago. Trains no longer operate on the Luscar Industrial Spur.

I would guess CN knew that the mine closing was coming and didn't want to expend the money to fix things - since they felt they could get by with bad brakes on all their other line; or the Car Dept personnel looked at the defect when it was warmer and the defects disappeared - like magic.
Wonder what would happen if the write up was "Car bcd defective brake outside air temperature - 25 degrees C temperature "
