The train is going to meet an eastbound oil train at Plain. Email Questions or Comments to the Webmaster or add a comment to the picture.

In the distance, on the main at Eisele (Clay), an eastbound UP coal train is waiting for the arrival of the Zephyr. Indeed, if you are unfamiliar with the geography and layout of the tracks here, welcome to the interesting engineering of Big Ten Curve!

Photo ID: 114189 Date Shot Photo By Thursday, August 6, 2026 Kevin Morgan Location Times Viewed CP DS019 (West Rocky) Arvada, CO 30 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Amtrak Cannot ask for better conditions than this, as the westbound Zephyr charges out of the west end of Rocky. This has the potential to be the last shot I take of the "standard" Zephyr of the last few decades. What do I mean by that? Both P42DCs are Phase 5, the baggage car is Phase 3, and all the Superliners are Phase 4b. Increasingly, as Amtrak shifts toward Phase 7 (including with the cars), it is more and more likely to see at least one Phase 7 engine or car on the Zephyr.

Photo ID: 114188 Date Shot Photo By Thursday, August 6, 2026 Kevin Morgan Location Times Viewed Eisele (Clay) (5,780 ft) Arvada, CO 33 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific While I'm not a huge of UP's latest paint scheme, it is always nice to see a freshly painted unit. This C44ACM must have been very recently (re)painted. I'm not a huge fan of the flag on the nose. The cab and nose just feel a little too busy, in my humble opinion. I also very much miss the wings on the nose. I would speculate that a lot of these changes were financially motivated, as the smaller flags and remove of the wings probably saves quite a bit of money on repaints.

Rumor has it that the West Elk Mine (the only mine currently loading by rail in Colorado) has some new contracts and is increasing their output, with the intention of loading more than 30 trains per months. Evidence of that is seen here with this meet between an eastbound and westbound train here at Eisele (Clay). Email Questions or Comments to the Webmaster or add a comment to the picture. Photo ID: 114186 Date Shot Photo By Thursday, August 6, 2026 Kevin Morgan Location Times Viewed CP DS020 (East Eisele (Clay)) Arvada, CO 40 (Add a Comment) Subdivision Railroad Moffat Tunnel (UP) Union Pacific At the east switch of Eisele (Clay), a westbound coal empty is too long to fit between signals. The eastbound load approaching is hoping they'll be able to fit on the main so the westbound empty can continue, clearing the east end. The engineer on the eastbound load has said that they have "250 feet remaining" until PTC will force them to stop. Email Questions or Comments to the Webmaster or add a comment to the picture.

However, a westbound coal empty is waiting here in the siding at Eisele (Clay) for the coal load on the main. The empty is up against the signal at the west end, but still has about four cars to go in order to get in the clear at the east end. The coal load is going to have to stop and hopefully will fit between signals on the main. Email Questions or Comments to the Webmaster or add a comment to the picture.

The dispatcher is gambling a little bit, having two coal trains meet at Eisele (Clay), which at 5,750 feet, is one of the shorter sidings on the Moffat.

An eastbound coal load is creeping along by the hotbox detector. You can see a pair of mid-train swing helpers off in the distance.

I am not sure when they will be returning to the train. In the meantime, a pair of UP SD70Ms continue to fill in as the power. The train is headed west at Plain, ready to make another round trip between Denver and Salt Lake City. It'll return east here next Sunday.
