What's a hump and yard?

Remotes are killing jobs

they do keep the welders busy at my shop... some of them get smashed up before the paint is completely dry after a repair [new frame section, bufferplate, coupler pocket and new draft gear, new pilot and hand rail uprights, new truck and traction motor...] the YO's can smash them up real good... 15mph to 0 real fast makes a big mess
