My son is in Hornpayn Ontario. He drives trains for CN rail. They are running the train lengths to only 6000 feet now because it takes so long to build air pressure to get the brakes off at -45C.
The other day it took 4 hours to build air to get the brakes off a 11,000 foot train. By the time they built air they only were legal to drive 8 hours with a 10 hour trip ahead of them. They had to load on a second crew to take over after their 8 hours were up.
If you go to the grocery store up there every parking spot has plugs for your block heaters. You plug your car in so it starts but also that you have heat right away when you come back out.
Cheers Don.
