The train was traditionally being called at 10pm in Grand Junction. However, UP has changed that and now the train is called as soon as the MNYGJ arrives. This means its arrival in Denver will likely be early morning or even pre-sunrise. Email Questions or Comments to the Webmaster or add a comment to the picture.

The rear of the train is about a thousand feet out of Rocky as the head end comes around the curve toward a clear signal at East Eisele (Clay).

UP's MGJNY is rounding the curve on the outside. You can clearly see the open hoppers filled with dirt on the inside of the curve, serving as a wind break for close to 50 years now.

However, 80 of them wound up in the 2500 and 2700 series. These 80 units are all known as Tier 4 "Credit" units. They were ordered after Tier 4 emissions standards were in place, even though they are Tier 3 units, by using "credits" UP had accrued. UP 2747 is one such unit, delivered in late 2016. Here, it is leading the MGJNY around Big Ten Curve on a largely cloudy morning. Email Questions or Comments to the Webmaster or add a comment to the picture.

A lot of graffiti has been applied to the open wind break hoppers in the last decade or so. They were repainted the tan-ish color you see in the 1990s. In the 25 years since (give or take), the blank cars became tempting targets for taggers. Email Questions or Comments to the Webmaster or add a comment to the picture.

You can clearly see the back end of the train, still being pulled up from Rocky, on the north side of Big Ten. These four units had a short stay in Denver as they actually led the Provo-Denver east in to town yesterday morning. Now, they had back to Utah.

The only manifest that UP still runs on the Moffat, the MGJNY, is nearing the end of its journey as it comes through the loops. It should be noted that the trains counterpart, the MNYGJ (westbound) still runs on the Moffat as well. Email Questions or Comments to the Webmaster or add a comment to the picture.
