Photo ID: 113813 Date Shot Photo By Monday, May 4, 2026 Kevin Morgan Location Times Viewed North Yard Denver, CO 37 (Add a Comment) Subdivision Railroad Yard Shots Union Pacific UP 3047 is one of roughly 200 SD70ACe-T4s that Union Pacific has on its roster. For the past decade, the EPA has mandated extremely strict emissions standards (known as "Tier-4" standards) for diesel-electric locomotives. Both Union Pacific and GE have locomotives that meet the requirements, but neither has experienced great success with sales in the United States. These units are more expensive up front, more expensive to maintain, and tend to be less reliable due to their complexity. Consequently, while a handful are in service, most railroads have instead created their own in-house rebuild program for older locomotives that are exempt, rather than spend extra money on purchases.

Not sure where this manifest is coming from, but there are a few possibilities. Most likely is that it is either the MCYNY (coming from Cheyenne, WY), or the MNPNY (coming from North Platte, NE). Here at Utah Junction, the train crosses BNSF's "New North Main" that runs to Cheyenne, and the Moffat mainline. Email Questions or Comments to the Webmaster or add a comment to the picture.

The Zephyr held the main while the oil train ran through the siding. It ended up being a rolling meet, meaning neither train had to come to a stop. With some crazy evening storm lighting, the oil train leaves Leyden westbound. Email Questions or Comments to the Webmaster or add a comment to the picture.

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.

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. Email Questions or Comments to the Webmaster or add a comment to the picture.

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.

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.

Photo ID: 113790 Date Shot Photo By Sunday, May 3, 2026 Kevin Morgan Location Times Viewed North Yard Denver, CO 34 (Add a Comment) Subdivision Railroad Yard Shots Union Pacific I was a bit surprised to find this old "triclops" SD60M sitting on the ready track in North Yard. I had heard that UP is slowly clearing out a lot of the units that have been stored in Grand Junction, which is likely where this relic of the 1980s and 1990s came from. Not sure if it is going to head for storage, a rebuild, sale, or the scrapper. Considering a chunk of the long hood behind the dynamic brake fan is missing at the top, I'm guessing the disposition might not be great!

Photo ID: 113788 Date Shot Photo By Friday, April 24, 2026 Kevin Morgan Location Times Viewed CP W511 Albany County, WY 44 (Add a Comment) Subdivision Railroad Laramie (UP) Union Pacific Here at CP W511, the Laramie Sub (Overland Route) passes underneath BNSF's Front Range Sub. There was a northbound BNSF manifest in the area, for a chance for a "over/under" shot was in the cards. Alas, the northbound stopped to walk the train after it sparked a few fires along the right-of-way south of Cheyenne. UP 4014 backs away from the camera, headed for home at the end of this western tour. In one month and one day, the Big Boy will be departed Cheyenne east for a massive journey that includes a trip on Norfolk Southern to Philadelphia.

The wye and tracks can leads west toward Laramie, north toward Cheyenne, or south toward Denver. Here, the Big Boy makes a reverse move on the southeast leg of the wye, and will cross over to Main 3 for the ten mile reverse journey to Cheyenne.
