There isn't much rail traffic where I live but I've been through other towns and seen trains passing through carrying a crap load of UPS Pups on them. I've never seen a UPS with a rail yard. I'm just curious about how the UPS rail system works. Do any of those trailers have packages on them? I was driving through Springfield, Tenn a while back and saw a train with UPS trailers on it and was wondering where it came from and where it might be going. I believe it was headed northwest. Anyone deal with this?
