On Tuesday evening a CP freight train struck a mudslide resulting in the derailment of 4 cars of glycol. Two of the cars landed in the Thompson River, although no leaks have been reported. I believe the train was westbound, operating on CN under their paired track arrangement.

Look on the bright side, the glycol in the river will make it more difficult to freeze over!

In the Fraser River Canyon, yes, it seems that either CP or CN gets a kick in the butt from Ma Nature regularly these years. Too bad. I don’t recall it being so problematic in the 60’s and on until just recently…maybe selective memory. But anyone who has stood at the side of the Trans-Canada highway and had a good look at much of that area will appreciate that it is difficult and treacherous terrain, and that’s when the weather is good.
A news blip on CNN said the tank car was leaking toxic chemicals into the river. Is this stretch of railroad as treacherous as it is it’s reputaion suggests? Is this both the CN and CP lines that have made the news in recent times?
CN’s line is definitely treacherous, being on the wrong side of the canyon. CP built through their first, and took the good side. The heavier westbound CN and CP trains both use CN’s line, and that is where most of the accidents have occured. This last one happened very close to where two CN locomotives were derailed by a slide in January 2007.
This thread has several photos of the Jan 2007 derailment-

Divers have been patching the holes in the two tankcars that are in the river, and it is planned to leave them there, with the glycol, for several weeks until the river flow has dropped to a safe level.
