With partly cloudy skies, the scene here at Cliff had been fluctuating between brilliant light and muted shade while waiting for this westbound coal empty to arrive. Alas, muted shade ended up being the conditions when it actually arrived. UP 6397 is facing a green signal as the train has picked up some speed, the max authorized speed increasing a bit here at Cliff. UP 6397 started life in scarlet and gray as SP 351 in August of 1995, so it certainly no stranger to the Moffat.

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.

A somewhat rare UP coal empty crosses CO-72 as it heads west on a green signal on the main at Cliff. At this spot, the tracks run between South Boulder Creek and the highway.

This location is something of a classic on the Moffat, as the Zephyr wraps around the tight curve on the approach to Tunnel 29, the shortest tunnel in the Tunnel District at only 75 feet in length. My dad has a shot of the Rio Grande Zephyr, with DRGW 5771 leading, from roughly this same perspective. Note the slight discoloration in the rock by the final Superliner, This used to be Tunnel 28, but was daylights decades ago due to cave-ins.

Deep in the Tunnel District, just west of Tunnel 26, passenger aboard the California Zephyr enjoy the views that only the Zephyr can bring! The train is high above South Boulder Creek, heading toward Tunnel 27.

AMTK 22 and AMTK 126 lead the morning Zephyr, which is running a little over an hour late. The train will lose a little more time as it is following the Rocky Mountaineer. At Rollins, the Zephyr would finally be able to run around the Rocky Mountaineer.

After getting a yellow (Approach) signal at West Crescent, the Zephyr is on the move again. It is following the westbound Mountaineer, which is just a block ahead.

Following closely behind the Rocky Mountaineer, the westbound Zephyr has come to a stop at a red signal at the west end of Crescent. As soon as the Rocky Mountaineer clears the block to the west of Crescent, the Zephyr will get a yellow (Approach) signal, allowing it to continue west as well.

After meeting an eastbound BNSF oil train at Crescent, RMRX 8600 (a former SD45, now an SD40M-2) heads west toward the east portal of Tunnel 19. Off in the distance, you can see Gross Reservoir is indeed growing (getting taller) as part of the project to triple the volume of the reservoir.

Too many trains and not enough track! This eastbound BNSF oil train was in the siding at Crescent, but could not fit between switches; the end of the train was hanging out the west end of the siding. Plain, Eisele (Clay), Rocky, and Leyden were all unavailable for a meet, so both the Rocky Mountaineer and the Zephyr came up to Crescent. The Zephyr got a restricting signal to follow the Mountaineer down the main. With the oil train finally able to depart east, the Rocky Mountaineer is now starting to pull to the west switch, as the Zephyr is stopped, waiting for the Mountaineer.

While there are no trains in this shot, I thought I'd post a shot of the progress on the raising of the dam. The project started in 2022 and is expected to be completed in 2027. The dam will be raised 131 feet, tripling the capacity of the reservoir, used for drinking water in Denver.

AMTK 29 and AMTK 14 leads the California Zephyr as it crosses the grade crossing at Crescent. AMTK 29 was on the Winter Park Express just last Sunday. It was taken to Chicago on the Zephyr, and has now returned as one of the units on the Zephyr itself.

The westbound California Zephyr, running right on time, heads west on the main track at Crescent. The siding at Crescent is only 5,550 feet long, so it definitely one of the less-used sidings on the east slope of the Moffat. No meets this morning for the Zephyr as it has a straight shot west up to the Moffat Tunnel.

An unexpected snow storm passed through the area the day before, leaving a couple of inches of fresh snow on the ground. A single C44-9W brings up the tail end of this southbound blade train, just south of Longs Peak.

Around 20 years after BNSF first unveiled its "New Image" or "Swoosh" paint scheme, you can still find Heritage 2 units on the rails. Indeed, here are two such units, both rear DPUs on the trains heading away from each other at the south end of the siding of Longs Peak. The siding of Longs Peak was actually built around 2004. Prior to that, there was a 60-mile gap between the siding of Broomfield and North Yard (in Fort Collins). Most trains could not fit on the relatively short siding at Boulder, so the introduction of Longs Peak help move traffic on the line.
