I've seen the grade next to your shop - hardly flat land! It is short enough not to cause too much grief, and I'm sure you're glad it isn't a mile long.
The interesting thing is it really isn't the grade or size of train itself - you can have a runway with one car or 8 cars or 107 cars, and the grade doesn't have to be 3%, there have been runaways on 1%.
This CN runaway is disturbing to me because part of the crew had already successfully survived one runaway without any damage or injury. Regardless of the actual cause, something went horribly wrong in the decision making process and common sense quickly flew out the window so it wouldn't have to ride the runaway. News reports are that one of the crew members that jumped has had to have vertebrae in his neck fused, not good for something that was probably preventable.
