Photo ID: 113588 Date Shot Photo By Monday, March 23, 2026 Kevin Morgan Location Times Viewed Rocky (7,330ft) Arvada, CO 34 (1 Comment Posted) Subdivision Railroad Moffat Tunnel (UP) Amtrak The westbound Zephyr just passed by some maintenance equipment in the siding and house track at Rocky. The Zephyr is about 25 minutes late this morning. UP's yard transfer between BNSF's 31st Street Yard and UP's North Yard was temporarily blocking the Zephyr down at Prospect Jct.

I think I've seen this one way more often than the Phase 1 through 3 heritage units. In any case, it is leading the Zephyr west around Big Ten Curve this morning, along with AMTK 23.

Even more surprising was CSX 1981 on the point. Along with Union Pacific, Norfolk Southern, and Amtrak, CSX has a "heritage unit" program. The lead unit is the heritage unit for Pan Am Railways.

The train is 11,500 feet long! Basically, two coal trains combined into one. 209 cars, three units on the point, three mid-train swing helpers.

The train is basically two coal trains combined, and they will split in Grand Junction, running to the mine at West Elk individually.

Photo ID: 113594 Date Shot Photo By Monday, March 23, 2026 Kevin Morgan Location Times Viewed Eisele (Clay) (5,780 ft) Arvada, CO 35 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) CSX, Union Pacific This is the longest train I've ever personally seen on the Moffat. The train is effectively two coal empties stuck together into one. Behind the three lead units (including a pair of CSX ES44AHs) is 105 cars. Then, there are three mid-train DPUs (hidden behind the hill at Big Ten). Behind those three mid-train DPUs is another 104 cars. The train is 11,500 feet long. When the head end reaches East Plain, the tail end will just be passing West Eisele (Clay)! At that length, there are only two sidings between Denver and Grand Junction in which the train could fit between switches: Allen in Glenwood Canyon (at 14,250 feet), and Palisade just east of Grand Junction (at 12,200 feet).

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.

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.
