Not too long prior to departure from Pine Bluffs, the steam team has replaced the Wyoming flag with the Nebraska flag on the front of Big Boy. This is one of the super classy things UP does, flying the flag of whatever state the Big Boy is (primarily) running in after a stop. Pine Bluffs, WY sits on the border with Nebraska, so in less than a mile, the train will be in Nebraska.

UP's steam chief Ed Dickens and several members of the steam team are applying water to an air pipe on the front of the Big Boy. During the maintenance stop, a gasket blew on the main reservoir. The team is going to have to remove the pipe and replace the gasket. In order to remove the defective piece, it needs to be cooled down.

UP 4014 has come to a stop on Main 2 in Pine Bluffs, WY so some standard maintenance can be done. The Big Boy stops every 50-75 miles when out on excursions to ensure everything is greased up and running as it should be.

This westbound Z-train has a single SD70ACe bringing up the rear as it hustles toward a crew change in Cheyenne on Main 2. Most of the train consist of COFCs (Container of Flat Car), but there are a few TOFCs (Trailer on Flat Car) with UPS trailers as well.

A westbound UP Z-Train is on Main 2 about 20 miles east of Cheyenne. Generally speaking, trains follow the "right hand rule" on the Sidney Sub. However, due to maintenance on Main 1, Main 2 is the only main open here at the moment.

UP 4014 and train are backing up the west leg of the wye at Speer Jct, which also serves as a connection track between the Laramie Sub and the Greeley Sub. UP's Z-train from Los Angeles to Denver (and vice versa) use this track, among others.

UP 4014 makes a reverse move on the west leg of the wye at Speer Jct. The train is leaving Cheyenne without a diesel, which is very cool to see and rather uncommon!
