As the head end of this eastbound BNSF oil train crosses over the large fill between Tunnels 2 and 3, we can see even more of the train to the right of the shot, wrapping around and into Tunnel 4.

An eastbound BNSF loaded oil train passes in and out of Tunnel 7, traversing along the Front Range of the Colorado Rockies. The crew on the train is running short on time, so the dispatcher is keeping them rolling east on green signals.

The morning Zephyr is headed west between Tunnel 16 and Tunnel 17. This is one of the longest stretches between tunnels anywhere throughout the Tunnel District.

UP 7816 leads a coal empty out of the west portal of Tunnel. Just around the curve behind the camera and to the right is Tunnel 4. Through the tunnel district, it can feel like you spend as much time in tunnels as out of them!

It was this time of year roughly 12 years ago that a "500 year storm" hit Colorado when it rained for four days straight. In that storm, the fill between Tunnel 2 and Tunnel 3 completely washed out, shutting down the Moffat for roughly two weeks. Fast-forward to this day as a westbound coal empty crosses the fill, through the cut, and toward Tunnel 3. In the distance to the left, you can see the back half of the train, still coming through Plain.

At the west switch of Plain, a westbound coal empty is getting ready to dive into the Tunnel District! As the lead unit rounds the bend, the crew is looking straight into the east portal of Tunnel 2.

The westbound Zephyr is moving along one of the longer stretches without a tunnel in the Tunnel District, between Tunnel 16 and Tunnel 17. This area is known as South Draw, and is absolutely one of the highlights of riding the Zephyr (or other passenger trains) on the Moffat.

The westbound Zephyr heads west through a cut that is known as "Old Tunnel 17". When the Moffat Route was originally be built in the early 1900s, the tunnel presented a lot of geologic problems, includes frequent cave-ins. The tracks were rerouted around a shoofly outside of the tunnel. That shoofly is now beneath all the pine trees on the outside of the cut in this shot. Old Tunnel 17 was finally daylighted, and the tracks were moved to their current alignment, now moving through a cut instead of a tunnel.

While Tunnels 9 and 28 were daylight quite awhile after the route had been in operation, they retained their numbers. Since "Old Tunnel 17" had issues from the beginning of construction, at was ultimately bypassed, the next tunnel to the west was numbered Tunnel 17 from the start.

Tunnel 16 is one of the longer tunnels in the Tunnel District, just two feet shy of 700 feet long. As a result, there is some exhaust that builds up in the tunnel, and you can see a bit of that exhaust coming out of the tunnel toward the left as the westbound Zephyr continues west in the Tunnel District.

UP is hauling their EC-5 track geometry car through the siding at Crescent. The geometry car assesses the rail geometry as it moves, ensuring compliance with FRA standards. It is also a preventative maintenance tool to look for damage. The car uses laser systems and vehicle/track interaction (V/TI) systems to perform its work.

An C44ACM, rebuilt from an AC4400CW, is the sole unit on a short work train that includes UP's EC-5 track geometry car. The car used to be self-propelled, but now requires it be pulled by a locomotive.

Five UP maintenance workers are walking the rails between Tunnel 2 and Tunnel 3, checking for defects. They found several tie plates that needed to be replaced, and marked them accordingly for a maintenance crew that will come out of Plain and replace them.

While the east half of Plain is one of the most commonly photographed portions of the east side of the Moffat, the west half is likely one of the least photographed portions as it is quite remote. Here, the Zephyr has come to a stop on the main at the west end of Plain. Passengers are going to have to be patient and wait for about 90 minutes for some track plate repairs to take place between Tunnel 2 and Tunnel 3.
