When the Zephyr departed Chicago yesterday, AMTK 207 was leading the train and AMTK 140 was trailing. Upon arriving in Denver, the position of the units was swapped so that AMTK 140 was leading. I am not sure why Amtrak swapped the units, but it was likely due to some sort of mechanical issue. Consequently, the train is a little over 90 minutes late. The train met an eastbound loaded oil train at Leyden, still visible in the distance.

BNSF typically runs loaded oil train on the Moffat with three units on the point and three on the end. Union Pacific has opted for three mid-train helper about two thirds of the way through the train. The first DPU, UP 7000, was originally GECX 4000 and was a warranty protection unit, built in 1997. It was subsequently bought by UP and added to the roster as UP 7000.

A majority of the last two years, Union Pacific has used the siding at Leyden for long term car storage. At the moment, however, the siding is empty and DS-378 is using the siding for a meet with the westbound Zephyr.

UP 8504 is sporting Union Pacific newest paint scheme. This is one of the first SD70ACes I've see with the new scheme. The train is headed for the siding at Leyden to meet a slightly late westbound Zephyr.

An eastbound loaded oil train wraps around the fill west of Leyden. The train is about to cross over Indiana Street and will then enter the siding at Leyden to meet the westbound Zephyr.

A trio of ES44ACs lead BNSF's Provo-Denver this morning. The tracks at Rocky are not visible from the highway at CO-72, which you can see in the distance (a few cars on it). But the tracks are not far below the horizon as viewed from the highway. From this perspective, we can also see west to Tunnel, and Plain, and even toward Tunnel 4.

Moffat Tunnel (UP) BNSF
About two hours earlier, BNSF's Provo-Denver came down the Moffat and took the siding at Rocky. The conductor tied some hand brakes and aligned the derail in the derail position. The derail exists so that, should the uncrewed train roll east for any reason, it will intentionally derail (away from the main track) before entering the main track. As you can see, a single switch point is creating a break in the south rail, which would result in the train derailing if it started to roll.

Always nice to see a little variation on the Zephyr, such as Amtrak's Phase 4 heritage unit leading the train this morning, getting ready to dive into Tunnel 1. It has been an unseasonably warm week with a lot of high winds. While the winds are not too bad right now, the temperature is already 60°F (16°C) at 10 o'clock in the morning in mid-December!

AMTK 164 and AMTK 77 lead the westbound Zephyr as it climbs the 2% grade up from the base of Coal Creek Canyon to the east portal of Tunnel 1. In the distance, you can see the paved road, interestingly named Moffat Road, that is part of the new Canyon Pines housing development.

At the west switch of Eisele (Clay), the westbound Zephyr has a green signal and continue west. The engineer is calling the foreman of a maintenance crew working west of Plain. The crew has a Form B active and a red board up, so the Zephyr needs to get permission to pass through the limits of the Form B

AMTK 164, Amtrak's Phase 4 heritage unit, leads the westbound Zephyr this morning as the train rolls west at track speed west of Leyden. The body of water directly behind the Zephyr is Welton Reservoir. The body of water further off in the distance is Standley Lake

The Zephyr got a short delay just east of Leyden this morning on its way west. A passenger on the train had to be removed from the train for reasons I was not able to figure out from listening to the scanner. Regardless, the train came to a stop with the last Superliner on the grade crossing at 80th Avenue, where Arvada police were waiting.

Apparently, one of the two P42DCs on the Zephyr was having some mechanical issues in Nebraska overnight, resulting in a delay arriving (and departing) Denver. Here at Rocky, the train is running roughly three hours late as it rolls west on the main track.

Looking west at Plain, the flatirons look pretty great covered in powdered snow as an on-time Zephyr rolls west on the main. This will be the last train for the next several hours (at least) as maintenance of way gets to own the railroad for a maintenance window today.

The Zephyr just knocked down a green signal at the east end of Plain. 6-7 inches of snow fell through most of the day yesterday, which is just perfect this morning as the Zephyr has a pair of highly colorful P42DCs (in Phase 7 paint) this morning.
