Three units, a pair of SD70ACes with an ES44AC splice in between, are all elephant style on the MGJNY as it rolls east out the east end of Leyden and across the 80th Avenue grade crossing.

UP's MGJNY can often been found headed east on the Moffat on Monday, Wednesday, and Friday mornings. This Wednesday morning was a great example, as the thrice-weekly manifest heads east on the main track at Leyden.

A trio of UP units represent the halfway point on this monster coal empty. 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.

The project to increase the height of Gross Reservoir is nearly completion, as you can see in the distance. 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.

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).

Three mid-train swing helpers, including a Tier-4 SD70ACe-T4, are roughly 105 cars deep in a 209 car coal empty that is making its way west to Grand Junction. The train is basically two coal trains combined, and they will split in Grand Junction, running to the mine at West Elk individually.

Alas, the clouds were out in force this morning, so the shutter speed was a bit low on this telephoto shot of CSX 1981, the Pan Am Railways heritage unit, lead a westbound coal empty at Rocky.

A bit of a surprise on the Moffat this morning, as a pair of CSX units (and a UP unit) lead a westbound coal empty. 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.

AMTK 164, the Phase 4 heritage unit, is likely the most common heritage unit to run on the Zephyr (and over the Moffat). 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.

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.

A couple of track maintainers are prepping a track regulator in the house track at Rocky, getting ready to do some work today. Meanwhile, the last train for the next several hours, BNSF's Provo-Denver, rolls by eastbound on the main track.

One of those times when the shot worked out just perfect! As the head end of the Provo-Denver approaches the west switch of Rocky, a pair of DPUs are coming around the east edge of Big Ten Loop on the tail end of the train.

A pair of ES44ACs bring up the end of the eastbound Provo-Denver around the east edge of the Big Ten Loop. The train is relatively short with 63 cars, but BNSF has three units on the point and two points on the rear.

Along the south edge of Big Ten Loop, this eastbound BNSF manifest is continuing east toward Denver. At the moment, it is running a bit below track speed. UP has some slow orders out due to some track work they have been doing in the area.
