As UP 7154 rounds the east edge of Big Ten Curve, we see the two DPUs bringing up the tail end back on the main at Eisele (Clay). Big Ten Curve is one of a handful of locations where a crew on the head end of their train can very clearly see the back end.

UP 7154 heads around Big Ten Curve in the foreground as the Canyon Spirit heads west in the siding at Eisele (Clay) in the distance. The two trains just met each other, and both are now continuing on their respective journeys.

Three units lead an eastbound oil train as it rounds the curve coming out of Eisele (Clay) on the south ridge of Big Ten Curve. There has been crazy high temperatures the last several weeks, browning much of the green grass. However, there is still quite a bit of green grass here.

Union Pacific has seemingly been bouncing back and forth a bit between the Moffat and the Overland when it comes to running oil trains. At certain points, UP oil trains seem to have completely disappeared from the Moffat. At the moment, however, they are certainly back. An eastbound load is leaving the east end of Eisele (Clay) on the coolest day in several weeks. It is only around 64ºF (18ºC) this morning for the meet with a westbound BNSF Denver-Provo and the Canyon Spirit.

Three trains, one scene! An eastbound UP oil train is slowly rolling on the main track at Eisele (Clay). BNSF's Denver-Provo and the Canyon Spirit are both in the siding for the meet. There was enough room behind the BNSF manifest for the Canyon Spirit to squeak in, clearing the main.

I know this scene is a bit blurry as the shot was taken from further away that I would have preferred. But in the scene, there is a three-way meet happening. An eastbound UP oil train is on the main, and BNSF's Denver-Provo and the Canyon Spirit are both in the siding at Eisele (Clay) for the meet.

One last roster shot of UP 4014 as it continues west on the Limon Sub toward Denver. The train will stay at North Yard tonight, and an employees-only showing of the Big Boy will take place tomorrow. On Wednesday, it will return to Cheyenne, and be put to bed in the roundhouse, likely for the rest of 2026. Hopefully, it'll be back on the rails in 2027.

I wish the sun had broken through the clouds for this shot of UP 4014 crossing over Kiowa Creek between Byers and Strasburg. However, even in the shot of the train comes across the bridge looks mighty fine. A great way to wrap up the day.

The traffic at Strasburg, CO, the final maintenance stop for UP 4014 today, was absolutely insane! As a result, I skipped Strasburg and went straight to the Kiowa Creek trestle. The train is descending a slight grade, headed for the trestle.

UP 4014 is crossing over West Bijou Creek on the west side of Byers, CO. Half of this trestle was rebuilt about 15 years ago. UP 4014 is over the rebuilt section right now, with the older trestle still visible further to the east beneath the passenger cars.

UP's Big Boy rounds the curve at Cedar Point along the 5,000 stub-end siding. Once upon a time, there was actually a wye here at Cedar Point. I don't know the exactly history, but I assume helpers might have once cut off here at Cedar Point after helping up the grade. Feel free to comment if you know the history!

UP 4014 slowly rounds the curve at Cedar Point, about 12 miles west of Limon. The siding of Cedar Point is just under 5,000 feet long, and is now a single ended track. The east switch has been completely removed, and it is now a 5,000 foot stub track, with access available only at the west end.

UP 4014 climbs the (roughly) 1.3% grade west here at Cedar Point. This is one of the steepest climbs along the Limon Subdivision, and UP 4014 is letting a bit of smoke loose in response to the increased grade.

UP 4014 heads west at track speed as it passes by a lot of viewers at the Limon Depot. The depot is now a railroad museum, and volunteers and patrons alike enjoyed seeing the Big Boy pass by.
