Union Pacific's Busy West Colton Railyard - Railfanning on a Rainy Day 12/31/2022

On this rainy last day of 2022, I went to West Colton Railyard again for more railfanning. It was quite busy for what I had anticipated to be on a weekend before a holiday, and got pretty good yard, and mainline action. The mainline tracks are part of the Union Pacific Alhambra Subdivision. Thanks for watching!
