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.

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.

Crossing over South Boulder Creek, two DPUs bring up the tail end of the Provo-Denver at Cliff. A pair of units DPU'd on the back of a manifest is pretty standard for BNSF manifests running on the Moffat.

It can sometimes be a bit of a challenge, capturing trains on the Moffat in direct sunlight in the height of winter. The low sun in the sky mixed with high mountain peaks keeps a lot of the line in shadows for much of the day. Here, the lead SD70ACe comes into directly sunlight on the main at Cliff as it crosses over South Boulder Creek.

The western 40% or so of Cliff hugs the north side of a mountain. Throughout winter, this part of the tracks never see any directly sunlight. As a result, it is pretty common for the rails to be buried in snow for months at time. Indeed, it is quite possible the tracks will be in snow until the spring melt. Meanwhile, an eastbound BNSF manifest rolls through the darkened scene.

After a stop in the siding at Rollins that lasted around 90 minutes, a relief crew for this Provo-Denver finally showed up. The crews swapped, and UP's DS-380 gave them a light to continue east. Indeed, there is nothing coming west out of Denver, and the train will have a clear shot to town. Here, the train is on the main track at Cliff.

BNSF 6087 is sitting in the siding at Cliff, having just met an eastbound Provo-Denver manifest. The west end of Cliff hugs the north foot of a mountain. As a result, it goes months without direct sunlight and, as a result, the rails also often spend months buried in the snow in the winter months.

An eastbound UP military train is coming to a stop in the siding at Cliff. The train is long enough that it is poking out the west end of the siding. The westbound Zephyr is not far off. Since the military doesn't fit between switches at Cliff, it'll be leaving just as soon as the Zephyr is clear of the east switch.

UP 8879 is about to come to a stop on the siding at Cliff. A westbound empty oil train is about 20 minutes away. After meeting the oil train, the coal load will continue east, meeting the Zephyr at Crescent.

This eastbound coal load is slowing as it rolls through the siding at Cliff. The house track is located to the left and the main, still cast in shadows, is on the right. The train will wait for a westbound unit oil train.

A pair of P42DCs in Phase 5 paint lead the evening Zephyr across the grade crossing in Cliff. The train is 45 minutes late as it rolls through the small town of Cliff. Rumor has it the State of Colorado hopes to expand rail service, potentially reinstituting some depots in small mountain towns such as Pinecliff.

A westbound oil train...the third overall of the afternoon...is sitting in the siding at Cliff waiting for the afternoon Zephyr. The Zephyr is running about an hour late and is not too far west of Cliff as of this shot.

A single C44ACM, sporting UP's newest paint scheme, brings up the rear of this westbound unit oil train. The train is going into the siding at Cliff to meet the eastbound Zephyr. A multitude of power lines crisscross, supplying electricity to the handful of residents that live in Pinecliff.
