Ahh, that clears things up. Thanks Crumm, I've never heard of such a thing before.
Hump yards
These are the largest and most effective classification yards with the largest shunting capacity — often several thousand cars a day. The heart of these yards is the hump: a lead track on a hill (hump) over which the cars are pushed by the engine. Single cars, or some coupled cars in a block, are uncoupled just before or at the crest of the hump and roll by gravity into their destination tracks in the classification bowl (the tracks where the cars are sorted).
Who's humping in the railyard?!!
Ahhh ok. As much as I have been in and out of CSX and NS railyards this last month I've never seen a UPS trailer in either one.

Union Pacific officials say one of the derailed tanker cars was carrying phosphoric acid, some of which leaked, and the other tanker car carried hydrochloric acid, some of which was somehow released as well.
