We were told that the railroad has a problem with a bridge over the Mississippi river, so the railroad is running "gypos", "expeditors", what ever you want to call them-to run our trailers from CACH to Portland Oregon, and back. I see at least 3 a day Westbound and a few Eastbound. I also see them running on Saturday and Sunday. They are not UPS sleeper teams. We also were told the railroad has contracted the drivers, and UPS has nothing to do with it. Any ideas?
