The train is 209 cars long, and is 11,500 feet long. Even though this is the halfway point of the train, over a mile of the train has already passed by.

In the foreground, we've got an extremely long westbound coal empty, led by a pair of CSX units and a newly painted UP C44ACM. CSX 1981 is one of 21 heritage units CSX has painted up, honoring the railroads that have gone in to making CSX. Email Questions or Comments to the Webmaster or add a comment to the picture.

It was great to see them again on this morning, heading west at Crescent. You can see Gross Reservoir to the right, slowly getting taller as part of a project to triple the water capacity of the reservoir.

From this vantage point, you can see the east end of Crescent, the grade crossing at Crescent, and Gross Reservoir in the distance. Of course, even further in the distance, you can see the mountains of the Continental Divide. Email Questions or Comments to the Webmaster or add a comment to the picture.

Tunnel 17 is the longest tunnel between Denver west to (but not including, of course) the Moffat Tunnel. Note the two private cars (Patrick Henry cars) on the end of the Zephyr.

Photo ID: 112983 Date Shot Photo By Sunday, August 31, 2025 Kevin Morgan Location Times Viewed CP DS036 (East Cliff) Boulder County, CO 509 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) BNSF BNSF 5830 just met the westbound Rocky Mountaineer, and is now departing Cliff on the main track eastbound. East Cliff is a bit of an interesting OS, as it is about 1,000 feet long. The curve of the track prevents the east switch from being visible from the grade crossing, so the signals at the east end are quite a ways west of the switch itself.

Even less common (in Colorado) are Norfolk Southern ET44ACs. However, there just happened to be one leading an eastbound BNSF oil train on the Moffat this afternoon. The train is coming through the shortest tunnel in the Tunnel District, Tunnel 29. Email Questions or Comments to the Webmaster or add a comment to the picture. Photo ID: 112926 Date Shot Photo By Monday, August 11, 2025 Kevin Morgan Location Times Viewed Tunnel 29 (MP 36.4, 75 ft) Boulder County, CO 472 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) NS, BNSF It is certainly possible that shots like this will become way more common in the next few years. On July 29th, Union Pacific and Norfolk Southern officially announced their intention to merge. We are probably 18 to 24 months away from a final decision, but if all the regulatory approvals go through, a lot of Norfolk Southern units might show up on the Moffat until they are repainted in whatever scheme results from the merger. In this picture, an NS ET44AC leads a BNSF oil train out of Tunnel 29. Email Questions or Comments to the Webmaster or add a comment to the picture. Photo ID: 112925 Date Shot Photo By Monday, August 11, 2025 Kevin Morgan Location Times Viewed Tunnel 28 (Daylighted) Boulder County, CO 464 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific This is a classic perspective of the tracks between (daylighted) Tunnel 28 and Tunnel 29. The red-ish rock just behind the last passenger car marks what is left of Tunnel 28. The reason for this passenger train was not known to any railfans. At least, no railfans I know. It was supposedly a deadhead move, although there was some speculation that perhaps it was related to the UP/NS merger announced on July 29th.
