Sure gonna be fun to clean up.

As someone said of another similar, much larger incident years ago (perhaps at Tehachapi?):
"Boxcar mine"
- PDN.
A photo on Global News Calgary from inside the tunnel shows a couple of empty centrebeam flats derailed. That might suggest it may have been a westbound descending the grade (2%, and 10D curve) and may make stringlining a less likely scenario. The lack of any better information makes any speculation on the cause at the moment little more than fiction.
...regardless, an unfun job in tight quarters and foul air. Yech
Is there an opposite term to "stringlining" that refers to cars being high-sided by buff force in a curve? 'Jackknifing' doesn't seem to apply, and 'accordioning' is a different set of physics on a larger number of cars.
Link to the Global News article. Apparently the train was travelling at 14mph which, if it was over a certain tonnage, was faster than the 10mph limit in the area. That was imposed after several heavy trains ran away in the 1990s. The ETT has very detailed instructions on train handling down the Field Hill. The crew may well have put the brakes in emergency to bring the train under control. It certainly did come to a stop.

(You still don't have the cause of derailment and conditions found....The L/V forces could also have rolled over rail, worn railhead issues, broken clips, cant, surface failure, truck componet failure, induced wheel lift and all kinds of "fun stuff" are still probably very much in play.) .... everything is pretty much hearsay right now. Very few people have actually been in there to see much of anything.
mudchickenCP is going to be looking at their switching, blocking and train makeup rules in mountain territory and how that train ever got out of the yard.
CP in general pays close attention to train marshalling. Even 45 years ago there were some simple rules, and the criteria have been much refined since then, as trains grew longer, heavier, and DPUs could be placed in various locations. But from time to time I'm sure something slips by, especially if a train lifts or sets out en route.
When EHH came on the scene I understood he had little patience with the instructions, since they could delay trains for remarshalling. In due course he realized that the resulting derailments caused even more delay, not to mention cost.

Tight curvature and steep mountain grades did not form part of his early railroading experience. Neither was railroading in -40F temperatures a feature of parts of the continent such as Memphis. As a self proclaimed railroad operating genius, it must have been quite a blow to his hubris to accept that sometimes the locals knew better.
You have to wonder about the education some people get in colleges these days. I literally had to show someone how to read a map today. Kid has a BA but has no clue what an atlas is for. He thought it was a picture book of the states.

Well, after a fashion, it is - if you consider the maps pictures...
I still carry some maps with me - there are times when they are a lot handier than using the phone, or even the tablet.
I frequent the Deshler railcam. Can't remember how many times I've told visitors there to go to a map/satellite site so they can get a better idea of the layout there. Usually the response is along the lines of, "Oh, wow. Now I get it. Thanks!"
I don't remember when I learned to read a map. I do not think it was in grammar school, but at home, perhaps before I finished the first grade (except for my brother who was not much older than I, all of my brothers had finished high school by the time I finished the first grade).
Larry, could your situation be because most road maps don't include railroads any more?I could locate my home town on a folding road map when I was in Kindergarten (brought it for show-and-tell, or whatever it was called then). In third grade we attempted to make a large-scale map of our part of the city, with models of our own houses and the school. I know my oldest grandchild was fascinated by maps when she was younger, but she's the one who helped me with GPS and finding directions thereon.Have the USGS topographic maps been usurped by new technology yet?

My first GPS unit did not show railroads. My second does.
Never too old to have a happy childhood!

That seems to vary by map. The more local the map, the more likely it is to include railroads.

I recall one of the satellite image sites that would tell you the elevation of a given point when you ran your cursor over it.
My map site of choice is Acme Mapper, which gives one the option of looking at maps, satellite images, and topo maps. Very handy for RR archeology, as the topo maps sometimes show predecessor owners.
Of course, there's also Historic Aerials, which usually has several years worth of topo maps for a given site.
Some old gousha (SP?) state gasoline station road maps had RRs on them.
zardoz in my industry they become Dispatchers and load planners. My husband has horror stories about some of these more modern students that became his dispatchers. One of them thought his truck with a governor on it could go from LA to Chicago overnight his response when my hubby asked for the airport and the C5 to load the plane on was it's only 2 inches on my map you can do that easy. Or the time the same idiot wanted him to go from Stockton CA to Ontario CA in less than 5 hours.
Guess what that guys job is at that carrier now Try VP of operations not because he got smarter he started dating then married the owner of the company daughter.

And I'm sure that kid with a BA could show you many things that you don't know about your phone or technology.
It's almost like you are different generations or something.
It's been fun. But it isn't much fun anymore. Signing off for now.
