You know with the instantaneous power output of electric drive trains and the low speed of freight trains, you might be able to reverse direction and get back up to a speed where the collision wouldn't be catastrophic. Though it would require rubber coated drive wheels. I don't think the collision danger should be a reason to not use these. They really could open up a whole lot more rail service on under utilized lines.
