The clouds were truly dramatic and dynamic, amplified by evening sunlight, as the eastbound Zephyr descends from Big Ten Curve and approaches a green signal at the west end of Rocky. One of the P42DCs...not sure which one...developed some mechanical issues on Donner Pass the previous day, and a UP loaner unit was added to assist.

The eastbound Zephyr is descending Big Ten Curve with a UP ES44AC on the head end. Hit the jackpot with the storm lighting this evening as there was a thin section of sky to the west between the clouds and the mountains, allowing the sun to light up the scene. The UP unit was added after mechanical issues developer with one of the P42DCs on Donner Pass.

The Zephyr is running about two hours late this evening, so the sun is well behind the mountain here at Eisele (Clay). Rays of sun still shine over the mountains in the distance, looking geographically north along the Flat Irons. The main reason for the Zephyr running late was mechanical, hence the ES44AC leading.

I'm guessing emerging from Tunnel 1 was a bit unpleasant for the Amtrak crew on the eastbound Zephyr, going from the relative darkness of the Tunnel and then descending the grade, facing directly into the setting sun to the west. Storm clouds are swirling around quite a bit off east toward the plains.

After a day with cloudy skies, there was a break in the clouds this evening to the west, setting up some dramatic shots. Dark storm clouds loom behind Tunnel 1 as the eastbound Zephyr, led by a UP ES44AC, heads east toward Denver.

The eastbound Zephyr encountered an issue on Donner Pass in California the previous day, and had to have a Union Pacific ES44AC added to assist for the remainder of the journey east. The train is crossing over South Boulder Creek just east of Tolland, under mostly cloudy skies.

The eastbound Canyon Spirit makes its way across Blue Mountain Drive by the Coal Creek fire station. It is a very pleasant afternoon, despite the overcast skies. Later in the week, the forecast is showing as much as 6-10" of snow might fall!

Unlike the California Zephyr, which is always trying to make track speed in order to stay on schedule, the Canyon Spirit typically runs below track speed, to extend the length of the trip and allow passengers to enjoy the incredible views they've spent a lot of money on to see. Here, the Canyon Spirit is descending from Tunnel 1 at about 15 MPH.

The eastbound Canyon Spirit has emerged from Tunnel 1, and is slowly descending the 2% grade toward the base of Coal Creek Canyon and the numerous S-curves ahead. In the distance, you can see the skyline of downtown Denver, where the train will ultimately stop and allow passengers to detrain.

Just east of the east switch of Leyden, BNSF's Provo-Denver has the typical three units on the point as the train rolls by a small storage shed, painted up like a small little red barn. Clouds are doing some crazy things this afternoon, looking threatening, but never releasing any moisture.

BNSF's eastbound Provo-Denver manifest was put in the siding for awhile this afternoon as UP had a work window on the main east of Leyden. The crew is short on time, having to make it to the yard by 3:30pm, just one hour from the time of this photo. Fortunately, the maintenance has clear and the train has a signal to proceed east. The crew assured DS-378 that they would have no issue making it to town within the hour.

A pair of GP38-2s are currently switching cars on the ladder in North Yard. The units are nose-to-nose, which is fine as visibility is not an issue. The units are being remotely controlled by a yard working on the ground, pulling pins and throwing switches.
