Do the math. A fully laden coal car weighs about 140 tons. I've never been 
bored enough to count cars when I stopped at a crossing but there are a 
lot of them. Let's say 30 for the sake of argument, 4200 tons plus the 
weight of the engines. Let's say 4 at 200 tons each. So, roughly 5000 tons 
traveling at 50 mph. That's quite a bit of kinetic energy to dump in 300'. 
I can hear snapping axles and see flying wheels.
