Even though I got a shot of it this morning, UP 1996 does not come through town very often, so I figured it was worth getting one more shot of it; I haven't seen it since 2020 prior to this sighting! It will depart this evening as the fourth unit on the MNYCY. When it comes to heritage units, none of them actually come to Denver particularly often anymore...

Power for UP's MNYCY (Manifest, North Yard, CO to Cheyenne Yard, WY) is all lined up with four units elephant-style. The fourth being UP 1996, the Espee Heritage Unit. There is a string of SD70Ms also coupled behind UP 1996, but they will definitely all be deadheading to Cheyenne when the train departs later tonight.

Swinging back by North Yard for the second time today, I found UP 1344 sitting, likely waiting for some light repairs. UP has laid off the vast majority of the folks capable of doing major repairs on engines in Denver. Anything too major will result in the unit being moved to North Platte, NE and Bailey Yard.

Something else worth mentioning is that this unit is very used to being in North Yard! It was originally delivered to Rio Grande as DRGW 3121 in September 1974! You can still clearly see where the MARS light once existed on the nose of the unit.

The paint on UP 4015 here is one year and three days old! Noticed this lettering at the back of the long hood which indicates the unit was painted at North Little Rock on April 8, 2025.

UP 4015 is the SD70M that is frequently assigned the duty of traveling with UP 4014, the Big Boy. However, this is not that same SD70M. When Union Pacific chose an SD70M to repaint as UP 1616 (the Abraham Lincoln unit), they chose to repaint UP 4015. About a year ago, UP decided to renumber UP 4392 as a "new" UP 4015. It received a fresh paint of coat in UP's newest scheme to go along with its new number.

On this Sunday morning, it was sitting amongst a string of half dozen SD70Ms, all waiting to head to Cheyenne. The other SD70Ms are likely headed for long term storage. UP 4015 is probably just headed back to the roundhouse in Cheyenne to serve with UP 4014 again in the future. I always appreciate how good units look in fresh paint!

A nice surprise on this Sunday was coming across the Espee Heritage Unit in North Yard! I'm not sure when it arrived, but I would guess it was probably on a train like the MNPNY, likely arriving in the dark. The unit has been serviced and will depart tonight on the MNYCY (North Yard to Cheyenne Yard).

Union Pacific's MNYGR, which runs from North Yard to Green River, WY, is in Track 8 at North Yard with three units, ready to depart for the Belt Lead and the Greeley Sub. However, UP's DS-378 is waiting for the Zephyr to come through first to ensure Amtrak is not held up.

A UP yard crewman just started up the prime mover in SD40-2 #1957. It is taking several minutes for the unit to fully warm up and, as a result, a lot of white exhaust is currently being produced. Also of note in this shot in UP 1019, a GP60. For whatever reason, UP seems to utilize GP60s in California and Texas quite a bit. They don't show up in Colorado all that often.

While waiting for the morning Zephyr, I got a shot of this C44ACM sitting near the fuel tracks in North Yard. This unit was originally a C44-9W, but UP rebuilt and converted it from DC traction motors to AC traction motors. The unit also sports UP's newest paint scheme.

One of the more interesting units to have ever existed! B-units were tried by various railroads at various times since the introduction of diesel-electric locomotives. Such units have a prime mover and traction motors, but simply lack a cab. This means they can only be controlled when they are in a consist with another unit (or units). EMD never produced an SD45-2B (seen here); rather, Santa Fe did a conversion program themselves that removed the cab from eight SD45-2s, creating B-units. I am not sure exactly what the reason was for doing this. If anyone reading this caption is aware of the reason, feel free to leave a comment!

This unit and this paint scheme really take me back to my childhood. As a kid of the 1980s, I remember seeing a few SD45-2Bs when my dad would take me out train chasing. It was really cool to see ex-ATSF 5703 here in North Yard, waiting to be moved to Iowa, hopefully for restoration.

A note on the door of this F40PH has a note indicated that the unit is running "dead in consist", and that the handbrake is located near the rear door. The cab doors are locked and inaccessible.

A few days earlier, I got a few shots of this ex-Amtrak F40PH at BNSF's engine house in Denver. The pervious day, the unit (along with an ex-ATSF SD45-2B) were transferred to Union Pacific. Here, the last F40PH delivered to Amtrak from EMD sits near the fuel tracks, waiting to head to Iowa.

A trio of UP GP38-2s sit in North Yard, UP 663 kicking up a ton of exhaust. All three of these units started their lives as Missouri Pacific units. Missouri Pacific, being primarily a high plains railroad, is one of a handful of railroads that ordered some units without dynamic brakes, deeming them unnecessary for the terrain they ran in. Today, such units are almost always relegated to yard service.

This UP GP38-2 has seen better days for a number of reasons. I'm guessing that it has spent some time either in the Houston area, or in Southern California, based on the extensive graffiti. Additionally, white exhaust is pouring out of the exhaust stacks as well. In a diesel-electric locomotive, this is generally indicative of unburned diesel fuel in the cylinders, sometimes from injection timing issues. However, it is possible that it might just be the result of a cold start, and the temperature this morning is only about 25°F, so if the unit was just started, that could explain the exhaust as well.
