Most likely, for the remainder of the 2026 season, a UP SD70M will be used along with the SD40M-2 on the Canyon Spirit. The GP40-3s are still waiting to be repaired (waiting on insurance) after the accidents last May. Here, UP 4073 currently has the duty along with RMRX 8086 at Cliff, meeting an westbound BNSF oil train.

This westbound BNSF empty oil train is making its way through the siding at Cliff, moving away from CO-72 for the time being as it has crossed over South Boulder Creek. Fall colors are just about at their peak.

A westbound BNSF oil empty approaches the bridge midway through Cliff that crosses over South Boulder Creek. Fall colors are looking pretty good here at Cliff, right around 8,000 feet above sea level. A pine tree has partially fallen here on the bank of South Boulder Creek, creating an interesting dynamic in the scene. The train is in the siding to meet the eastbound Canyon Spirit, already out of Rollins.

The eastbound Zephyr is running about 40 minutes behind schedule as it glides east on the main track at Cliff along South Boulder Creek. The Zephyr was the seventh train to run through the Moffat Tunnel during daylight hours on this last official day of summer for 2026. A great day in the Colorado High Country!

BNSF 5616 is pulling into the siding at Cliff, approaching a red signal at the west end. It is getting in the clear so the morning Zephyr can overtake the train. The Zephyr will pass by on the main track. DS-378 is doing his best to keep Amtrak moving, giving it the highest priority he can.

I could not have asked for a better day for getting some shots along the Moffat. Barely a cloud in the sky and temperatures right around 55°F (13°C) as the Canyon Spirit rolls by on the main at Cliff.

Two gondolas sit in the house track at Cliff, possibly being used for the collection of used ties along the right-of-way after the months-long tie and ballast project from late 2025. It is also great seeing EMD spartan cabs on the main, with the Canyon Spirit rolling east.

A trio of SD70ACes, running elephant-style, lead this eastbound loaded oil train toward the east end of Cliff. The train was in the siding here for the Zephyr, but DS-378 has set up the signal at the east end, and the train is on the move.

After meeting the westbound California Zephyr, this eastbound BNSF coal train has its lights back on bright and is ready to start rolling east toward Denver.

The Rocky Mountaineer is running west through the siding at Cliff, meeting a BNSF oil train that is on the main. DS-378 is keeping the oil train on the main to help it keep its speed up after the meet. The crew has less than two hours left on the clock. At this point, it is not clear if the train will be able to make it in to Denver or not.

Lighting is not the best, but the westbound Rocky Mountaineer has taken the siding at Cliff to meet an eastbound BNSF oil train.

After meeting a very late westbound Zephyr here at Cliff, this eastbound BNSF oil train is preparing to depart east. While DS-378 has set up a clear (green) signal out of Cliff, PTC is still showing a red. The engineer would log out of PTC and log back in, resolving the issue and allowing the oil train to depart eastbound.

The westbound Rocky Mountaineer crosses CO-72 at the east end of Cliff. Like so many siding, Cliff has a house track off the siding. The track is currently empty, but has about 1,000 feet of storage space, if it is needed.

Roughly halfway through the block at Cliff, the main and the siding both cross over South Boulder Creek. Here, the four units on this westbound coal empty are crossing over that exact bridge as they continue west on the main track.
