Above the work train, in the siding at Eisele (Clay), an eastbound UP manifest is patiently waiting its turn to head east. It has held in the siding for two westbounds (the Zephyr and BNSF's Denver-Provo), and is now waiting on the work train. Email Questions or Comments to the Webmaster or add a comment to the picture. Photo ID: 113180 Date Shot Photo By Saturday, September 27, 2025 Kevin Morgan Location Times Viewed Big Ten Curve (MP 19.5 to MP 20.2) Arvada, CO 124 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific At first glance, this might appear to be a unit covered hopper train. While it is almost exclusively covered hoppers, you can see two tank cars off in the distance. This is an extra train, with the symbol MDVBOX-27. All the cars on this train are headed for industries on the Craig Branch. Normally, the cars would be added to the MNYGJ and the cars would be set out at Bond. However, the sheer volume of cars have necessitated this extra train. A rare sight indeed on the Moffat. Email Questions or Comments to the Webmaster or add a comment to the picture.

Slowly, Amtrak is going through the process of repainting the entire P42DC fleet in Phase 7 colors. Here, the morning Zephyr is climbing the north edge of Big Ten curve.

Multiple sunflowers are growing on the south edge of Big Ten Curve as BNSF's Provo-Denver heads east on the final 20-ish miles of the journey.

In June, UP's passenger equipment ran west over the Moffat. In July, UP 4014 brought a train from Cheyenne to Denver. Then, UP 1616 did the same thing on the Greeley Sub. Later, passenger equipment went west over the Moffat. Now, a UP engineering special heads west, climbing the north leg of Big Ten Curve, with a single SD70M for power.

The van driver that is picking the crew up is new to the territory...she drove past Rocky and was halfway up Big Ten when she met the eastbound train. The crew told her she should turn around and go back to the east end of Rocky. You can see the van on the right side of the shot, getting ready to turn around.

Not sure precisely what the mechanical issue was, but due to that and a few other delays, the Zephyr is six hours late as it rounds the bend on the approach to Eisele (Clay).

The Zephyr is on the south edge of Big Ten, and is headed into the afternoon light. A bit unusual to have these lighting conditions for the westbound Zephyr, but it is running six hours late.

This afternoon, there are some fast-moving clouds, with shadows moving quickly through the scene. Fortunately, this shot was taken just before the shadow at the top fully encompassed the scene.
