Two UP Trains. Two Subdivisions. One Spot. Winter 4K.

Experience a crisp winter morning on the legendary Cajon Pass, where two Union Pacific trains were filmed back‑to‑back from the same vantage point overlooking two different railroad lines. One vantage point. Two subdivisions. Pure Cajon Pass. Captured in crystal‑clear 4K telephoto, the cool winter air and deep blue sky bring razor‑sharp detail to every frame, revealing the dramatic sandstone formations of the Mormon Rocks in perfect clarity.

The first train is an eastbound Union Pacific empty iron ore train, rolling through the Walker section at Milepost 59.8 on BNSF Main Track 1. In the still winter atmosphere, the train emerges cleanly from the distance, its headlights cutting through the cold morning light as the deep blue sky contrasts against the rugged cliffs of the Cajon Subdivision.
These ore hoppers also feature the familiar color‑coded corner panels used on rotary‑dump cars. The bright markings help crews instantly identify which end of each car is equipped with a rotary coupler, allowing the car to be inverted in a dumper without uncoupling the train. Most fleets use yellow to mark the rotary‑coupler end and red or orange for the non‑rotary end, though some railroads use white or green depending on the builder and era. In the crisp winter light, those colors stand out sharply, giving railfans a quick visual cue about how the train is oriented for unloading.

Shortly afterward, from this same winter vantage point, a southbound Union Pacific manifest appears on the Palmdale Cutoff at Milepost 468.7 on the UP Mojave Subdivision. The clear air and bold blue sky reveal every detail of the mixed freight consist as it winds along the elevated track, creating a dramatic upper‑level scene above the desert landscape.

Though filmed separately, these two trains showcase the unique geometry of Cajon Pass — two major railroad lines stacked across the terrain, both visible from one location in pristine winter conditions. From the crisp echo of horns to the clean rumble of steel on rail, this is winter railroading at its finest.
