UP 8205, leading the ZLBDV-12, knocks down a Diverging Approach (red over yellow) signal at the north end of Carr, heading in to the siding. The northbound train that is being met is already between switches on the main. Should be just another few weeks and the trees here will have their leaves back for the summer.

A northbound coal empty holds the main track at Carr, CO. The train is ultimately headed for the Black Thunder Mine in the Power River Basin in Wyoming. The train is currently holding for a southbound Z-Train that is just minutes away from the north switch.

A northbound military train sits in the siding at Carr, waiting its turn to continue north, as a southbound military train approaches a clear (green) signal in the distance at the south end of Carr.

It appears that the red signal on the siding at the north end of car is not currently working. As you can see, BNSF 6272 is looking at a dark signal as a southbound clears the north switch. Fortunately, crews treat a dark signal as though it is a red signal. I was not around to see if the signal successfully lit up green when it was time for the train to depart.

Fort Carson has loaded up some military equipment and sent it north toward Yermo, CA. That is the train sitting on the siding to the left. Ironically enough, Fort Carson will soon be receiving some new equipment as southbound military train passes slowly by on the main.

The US military does ship equipment by rail, but coming across a military train is pretty rare. They are certainly no common. So imagine my surprise when I just happened to stumble across a meet between two loaded military trains at the siding of Carr in northern Colorado!

A trio of elephant-style GEs leads a southbound military train across Lone Tree Creek at the north end of Carr. The train is holding the main, but is restricted to 25 MPH as it is meeting a northbound military train with some "wide" equipment on board. The speed restriction will ensure both trains clear one another.

Just north of Carr on the Greeley Sub, a southbound military train with a trio of UP units is approaching. The train originated in Yermo, CA and is headed for Fort Carson.

Crossing over Lone Tree Creek, this northbound manifest is leaving the final siding on the Greeley Sub, Carr, behind. The next stop will be Speer, Wyoming, where a crew change will take place.

A southbound local slowly rolls toward a red signal at the south end of Carr as the northbound it is meeting descends from the horizon on the approach to the south switch. UP's DS-14 has set up for a pretty good meet between the two trains.

86 miles north of Denver, at the north switch of Carr, a southbound local crosses over Lone Tree Creek as it approaches a diverging approach (red over yellow) signal. It will be taking the siding to meet a northbound manifest. Fall colors are starting to show their...well...colors!

Starting in 1997, the EPA (Environmental Protection Agency) passed regulations on exhaust emissions for diesel locomotives. Five tiers (Tier 0 through Tier 2) were identified, with each higher tier having a requirement for cleaner emissions. Tier 0 applied to locomotives built between 1973 and 1992. Tier 1 applied to locomotives built between 1993 and 2004. Tier 2, which was the first real major decrease in emissions, went in to effect for locomotives built in and after 2005.

In 2008, the EPA added Tier 3 and Tier 4 requirements. Tier 3 applied to units built between 2012 and 2014, with Tier 4 starting in 2015. The Tier 4 standard required an 89% reduction in nitrogen oxides and a 93% reduction in hydrocarbons compared to Tier 0 standards. Compared to Tier 3 standards, nitrogen oxides required a 74% reduction and hydrocarbon required a 77% reduction

It took both GE and EMD years to develop locomotives capable of meeting the regulations. The designed were complicated and the units were expensive. In the case of EMD, they could no longer use a two-stroke engine, and instead had to move to a four-stroke (12-cylinder) engine, similar to GE.

Now, in 2023, UP still only has 87 SD70ACe-T4s (the Tier 4 compliant unit from EMD) on the roster. Most railroads have instead chosen to rebuild older units as rebuilds have lower emissions requirements and are far cheaper. One of the 87 SD70ACe-T4s is seen here, third unit at Carr on this southbound manifest.

A southbound manifest knocked down the signal at the north end of Carr and enters in to the siding to meet a northbound empty grain train. The crew on the manifest will ask the crew on the grain empty to let them know when their last car is clear of the grade crossing. The crew on the manifest is calculating their train length as they believe there is a discrepancy from their train manifest. Their suspicion was correct, as the manifest showed 4,600 feet and the actually length was 5,700 feet. Turns out the discrepancy was due to a technology error with their (electric) manifest. A quick call with UP support got everything straightened out.

Now we are cooking! In true GE fashion, as the westbound Zephyr starts to accelerate, AMTK 180 belches out not only quite a bit of exhaust, but some pretty decent flames as well from the exhaust stack! GE units are notorious for doing this, although newer models seldom have this happen anymore.
