The power, a UP unit, was uncoupled and parked a few hundred feet away. I am guessing that the inspection train will depart Monday morning. The Denargo wye connects BNSF's 31st Street Yard and UP's 36th Street Yard. About 15 years ago, it was upgraded to welded rail and the one grade crossing on the line was upgraded. Ironically, with UP now using 36th Street only for local preparation and storage, and not for classification, the wye is never used. This is probably the first piece of equipment that has been on the wye in months, if not year. Email Questions or Comments to the Webmaster or add a comment to the picture.

The FRA has a couple of inspection cars that are often sent out to inspect the rails all across the United States. These cars are sometimes on Amtrak, and sometimes just on freight trains.
