Moffat Tunnel (UP) Rocky Mountaineer
The Rocky Mountaineer is sold out for this westbound run out of Denver. It is great to see both the GP40-3s back on the train as it slowly climbs Big Ten. There is an eastbound UP manifest on the main at Eisele (Clay).

I am not sure why UP is running an empty eastbound coal train, but I would assume these cars had been in long term storage somewhere, are either being put back into service, being moved to a new location for storage, or sold/scrapped. The train is passes by some fresh rip rock that will be used to shore up the track here.

This eastbound BNSF oil train creeps through a work zone on Big Ten Curve. This was the location of a derailment last Friday. One truck on BNSF's Provo-Denver derailed. Since then, UP has started a broader construction project to shore up the rails.

Moffat Tunnel (UP) Norfolk Southern, BNSF
Lately, there have been quite a few Norfolk Southern units showing up on the Moffat, leased from NS for BNSF. Not sure why that is the case, but here is a (rebuilt) AC44C6M in the middle of two BNSF units, leading an oil train eastbound.

An eastbound BNSF oil train has two BNSF units with a Norfolk Southern cut in between the two of them. The train is slowing for a 10 MPH slow order through a work zone just ahead on the other side of Big Ten Curve.

A track tamper, which has been working on Big Ten Curve, and a hyrailer are both rolling east down the grade back toward the main track at Rocky. They are clearing up for a westbound rail train.

UP 5772 leads UP's Grand Junction to North Yard manifest around the north edge of Big Ten Curve. Note the solar-powered weather station to the right. It measures, among other things, the current wind speed and reports it back to UP headquarters in Omaha. If the wind speeds are high enough, a 10 MPH slow order is issued around Big Ten.

A dump truck dumps out a load of ballast that will be used in repairs of the track where a derail occurred last Friday morning. An eastbound BNSF Provo-Denver had a truck derail on a tank car. No cars fell over, but there was some track damage. You can clearly see the fresh ballast that has already been laid. A track foreman just checked the gauging here, and is informing DS-380 that a track tamper needs to run through here before two eastbounds. Also note the flood light which has been used at night as crews have been working around the clock to get operations back to normal.

Right after the westbound Zephyr passed by, a UP maintenance foreman received track and time from DS-380 to check the train gauging at the location of a derailment here on Big Ten last Friday. You can see a dump truck showing up, ready to drop some fresh ballast.

The leaves on trees are working on making their spring comeback as the eastbound Zephyr descends from Big Ten Curve. AMTK 203, painted in commemoration of Operation Lifesaver's 50th Anniversary, is leading the train this afternoon. A number of spring storms have been rolling through the area, creating some fantastically dramatic clouds to the east.

After an afternoon of overcast skies, the sun managed to squeak through some clouds and make an appearance at the perfect time! Great light was cast on the eastbound Zephyr as it descends Big Ten Curve with Operation Lifesaver P42DC, AMTK 203 leading the way.

AMTK 203 leads the Zephyr around Big Ten Curve, passing by the hoppers that have now sat, motionless, on the inside of the curve for over five decades. The Denver skyline, where Union Station is located, is visible to the left. Union Station is indeed the next stop of the Zephyr this evening.

Helping on this westbound coal load is a Norfolk Southern AC44C6M. I actually shot this exact unit about 24 hours earlier, when it was sitting near the BNSF Engine House in Denver, awaiting its next assignment. At the time, I would not have guessed its next assignment would take it west on the Moffat.

A BNSF coal load climbs Big Ten Curve, headed west on the Moffat. The train loaded in the Powder River in Wyoming, and is headed for the Valmy Power Plant in Nevada. This coal train's days are actually likely limited. Like so many other power plants, the Valmy station is transitioning to natural gas. The coal-burning stations are slated for retirement by the end of 2025.

The Zephyr wraps around the final bend of Big Ten Curve, toward a clear (green) signal at the east end of Eisele (Clay). It is a cloudy and morning with fresh snow on the ground. After a high temperature in the mid-70°Fs yesterday, it is only 30°F this morning.
