Is there a prototypical standard for which end the break wheels should be on rolling stock? Should they be on the front of the boxcar (towards the engine) or the back (towards the caboose)? I would think there is a standard of some sort to keep the brakes all pulling the same way but I could be wrong? Is there a specific direction they should go? I've never actually looked before since I've always been more interested in the engines and cabeese than the rest of the rolling stock.
