Photo ID: 113252 Date Shot Photo By Sunday, October 19, 2025 Kevin Morgan Location Times Viewed Mesa to Watkins Adams County, CO 55 (Add a Comment) Subdivision Railroad Limon (UP) Union Pacific When I saw the headlight on the horizon, I originally thought this was going to be the Limon Local. I was pleasantly surprised to find an eastbound loaded oil train instead, heading out onto the plains on the Limon Sub. Considering how few trains run on the KP, this was a nice surprise.

Photo ID: 113251 Date Shot Photo By Sunday, October 19, 2025 Kevin Morgan Location Times Viewed Mesa to Watkins Adams County, CO 53 (Add a Comment) Subdivision Railroad Limon (UP) Union Pacific An eastbound oil train has left CTC limits behind at Mesa and is now headed east in TWC (track warrant control) limits. So why is there a trackside signal? And an ever better question...why is the signal yellow when the train is in the block beyond the signal? The key is the "D" plate located on the signal mast near the bottom. That "D" plate indicates this is a "distant signal". This signal does not give any occupancy information about the block ahead. It only gives westbound trains an indication of the CTC signal at the east end of Mesa. Since that signal at East Mesa is currently red, this distant signal shows a yellow (Approach) indication. If the signal at East Mesa were green, this signal would also show a green. Even with something in the block immediately beyond the signal. Indeed, in TWC limits, there are no "blocks" per se.

The longer "snoot-nose" once held extra radio equipment. I don't think it is actually used for anything like that today. Still, looks a little different from most of the other SD40-2s built!

This coal train loaded at the West Elk Mine on the North Fork Branch two days ago. Fortunately, the engineer setting up the power in Grand Junction set up 1982 to lead east.

The train was called in Grand Junction at 10:30pm the night before and actually made amazing time. Was hoping to get a few shots of the train on the Moffat, but it was in Denver by 7:00am and had a new crew called at 8:15am.

The units were built by Siemens and are headed for Pennsylvania. RTD's "A Line", which runs from Union Station to Denver International Airport, follows UP's Limon Sub for much of the run.
