Ralph,

A lot of the big switching rail yards run the various cars up an incline and when they go down the other side they are automatically switched to various sidings to make up the completed train.  It is not wise to hump tank cars as if the automatic braking go awry you could end up in a world of s***   

Here is an URL that explains it much better than I can:
