Rare 5x2 Port Stacker at Walker – Cajon Pass

A rare 5x2 port stacker working through Walker in Cajon Pass is always worth stopping for. These stack trains come straight out of the ports and move an entire block of containers inland in one solid movement, which means big tonnage and serious power on the climb. I filmed this one right at the crossing at Walker, where the sound carries perfectly as the train digs into the grade. Five units up front and two on the rear made for a clean, heavy run through one of the most iconic spots on Cajon. Clear light, steady wind, and that classic Walker echo came together for one of those catches that just feels right. 🚂 Train Info Consist: 5x2 distributed power Train type: Port stacker (full block movement) Origin: Ports of Los Angeles / Long Beach Location: Walker crossing, Cajon Pass Power: BNSF GEVO lash‑up with rear DPUs The two rear units, 3755 and 3722, are ET44C4 helpers that specialize in shoving big stack trains up to Cajon Summit. They work out of San Bernardino with a two‑man helper crew, cut away from the train at Silverwood, and return downhill when there’s an opening so they can do it again. It’s a constant cycle of shove, cut off, drift back, repeat — pure Cajon railroading. Port stackers are built around destination blocks, not just length. When the blocks line up cleanly, BNSF can run a long, heavy train without inserting mid‑train power. Rear DPUs provide braking control and shove while the five‑unit head-end does the pulling. rare 5x2 consist, port stacker train, port block train, Walker Cajon Pass, Walker crossing, BNSF 5x2, distributed power, Cajon Pass trains, heavy freight train California, port of LA trains
