Double Titans at Sullivan’s Curve — 8‑Unit UP Mega Manifest vs. BNSF Westbound Monster

🎬 A Railfan’s Journey in 4K: The Sullivan’s Curve Double Titan Showcase
High in the rugged backbone of the San Bernardino Mountains, where the desert wind carves ancient lines into stone and the rails cling to the earth like veins of steel, two giants rise to challenge the grade. This is Sullivan’s Curve — a place where trains don’t just pass… they perform. On December 21, 2025, this crisp 2160P 4K UHD footage captures the sheer power and presence of these iconic machines. Adjust your settings, settle in, and take in the ride.

In this 4K double‑feature experience, you’ll witness two colossal forces battling gravity, distance, and the unforgiving sweep of the mountain.

🚂 Feature One — The Union Pacific Eight‑Locomotive Mega Manifest
From the far edge of the horizon comes a steel giant:

3 lead locomotives charging up the grade

4 mid‑train DPUs thundering like a relentless heartbeat

1 trailing DPU holding the line at the rear

Eight engines. One purpose.
A train so immense it seems to warp the desert air in its wake.

As it enters Sullivan’s Curve, the entire canyon becomes an echo chamber — a deep, resonant roar that shakes the ground and rolls across the valley like thunder. Every wheel, every coupler, every surge of horsepower is captured with cinematic clarity.

This is raw, unfiltered mountain railroading.

05:19 🚂 Feature Two — The BNSF Westbound Stack & Baretable Monster
From the opposite direction comes a rival force — a BNSF westbound stack/baretable consist stretching across the horizon. Powered by a fierce lash‑up of five locomotives — three up front and two trailing DPUs — this train slices through the pass with speed, precision, and the unmistakable orange‑and‑black authority of the Transcon.

Long strings of baretable cars rattle like skeletal steel. The DPUs shove with relentless determination as the train sweeps through the curve, carving its own signature into the mountain.

This is the other side of Cajon Pass — fast, modern, unstoppable.

🌄 Two Trains. One Curve. One Epic Experience.
Captured in stunning 4K, this double feature brings you the full spectrum of Cajon Pass railroading — the brute strength of a Union Pacific mega manifest and the high‑speed precision of a BNSF westbound titan.

No commentary.
No distractions.
Just the pure, cinematic power of steel meeting stone.

Settle in.
Turn up the sound.
And let the mountains speak.
