Even so, I'm surprised that modern safety systems don't automatically apply the brakes of the wagons when the connection to the locomotives is lost. It's not an American continent thing either, we had a runaway on the London Underground a few years ago that chased a passenger train, fortunately there was no impact, but the fact that it happened indicated some sort of braking system on the wagons is either not in place or is inadequate to cope with the gradients on the routes it travels.

There is some speculation that the proper amount of handbrakes were not applied to deal with the gradient involved. I'm also surprised to find out that the Montreal, Maine & Atlantic railroad received approval in May/2012 for Quebec of single person operation assisted by a remote control caboose:

Not sure if that was the case here but if so, it seems that may of been a huge contributing factor as to why not enough handbrakes were set if that turns out to be true.
