This is a very interesting shot looking straight down on a truck that, prior to a derailment in August, had been on BNSF 4272. I say it is interesting because it really demonstrates some of the mechanics of GE's ES44C4. The unit is a A1A-A1A unit, meaning only four of the six axles are powered. As you can see here, a traction motor is attached to the axle on the left, but the center axle is a "dummy" axle. The axle on the right, were it still intact, would also have a traction motor attached. You can also see some of the hydraulics that GE uses to slightly lift the center axle up when necessary to provide more tractive effort, the weight resting more on the powered axles.

Unfortunately, derailments are a part of life for railroads. Most derailments are minor, with only a single axle or maybe a truck derailing with everything remaining upright. However, sometimes things are work. BNSF 4272 toppled onto its side when its train (a southbound intermodal train) struck cars that had rolled out onto the main track at the south switch of Boulder.

A little over a month earlier, on August 22, 2024, cars that had been stored in the siding at Boulder rolled out on to the main track. A Southbound intermodal train struck the cars and derailed. BNSF 4272 was one of the units involved in the derailment, and the final piece of the equipment that has been waiting to be removed from the site. Today, BNSF worked with Hulcher to load the unit on a special flat car for transportation. The crew ran out of time, so the train was tied down in the siding for the night.

A very short BNSF manifest is tied down in the siding at Rocky, awaiting a recrew. Note that the derail is set at the east end. This is to protect against the possibility of the train rolling out onto the main track. Were the train to roll, it would be derailed away from the main track. Fortunately, the likelihood of that happening is near zero as the train has hand brakes applied on the train, and the engines are continually charging the brake line to keep the train brakes applied.

A pair of ES44ACs, one Canadian Pacific and one BNSF, bring up the rear of BNSF's Provo to Denver manifest, currently tied down in the siding at Rocky. The train is actually quite short, at only 3,100 feet in the length, meaning the back half of the train is not wrapped around Little Ten Curve.

Just west of the siding of Crescent, deep in the middle of the Tunnel District, a westbound oil train curves toward the east portal of Tunnel 19, just out of view to the left. The train crosses one of dozens of fills in place to accommodate the rails here in the Colorado Rockies. Off in the distance, you can see the dam the creates Gross Reservoir. Indeed, the dam is currently undergoing a project to raise its height by 131 feet. If you look closely, you can see some climbing cranes on the scene, being used in the construction.

In 2024, mainline locomotives almost universally have around 4,400 horsepower. As a result, fewer units are typically needed on the head end of trains. Whereas 5 or 6 units was not uncommon 40 years ago, 2 or 3 is often then case in 2024. So, it is rather cool to come across a train like this, with 6 units on the head end. These units will be distributed throughout this oil train for the trip east, when the (loaded) train is far heavier than the current empty.
