Union Pacific Restarts Trains Near Portland’s Deteriorating Centennial Mills Warehouse
8/9/2026, 12:55:44 PM
Core Event
Union Pacific announced it will restart freight trains through the corridor adjacent to the burned-out Centennial Mills warehouse in Portland’s Pearl District. The company plans to run the first trains on the Sunday following the suspension that began after a massive fire forced Portland Fire & Rescue to halt traffic for safety reasons.
Background and Safety Concerns
The historic warehouse suffered a large blaze that left the structure and its rooftop water tower unstable. City officials have ordered the property owner to begin demolition within two weeks and have warned that “crack widths are increasing” and the building is leaning west toward the rail lines. Portland Fire & Rescue’s lead investigator has not determined the fire’s cause and has not ruled out arson. Police have also disclosed a “high likelihood” that human remains lie beneath the rubble, complicating demolition and investigation efforts.
Official Statements & Mitigation Measures
To reduce risk, the company will position personnel on site, run trains at no more than 10 mph, use loaded ballast cars on the eastern track, and prohibit trains carrying toxic or hazardous materials through the area. The city’s administrator, Raymond Lee, responded that the “significant danger” of a collapse could endanger trains and the public, and he insisted that Union Pacific keep a hazmat team and vibration-monitoring devices on site.
Community Concerns
Local residents have voiced alarm over the possibility of an uncontrolled collapse.

- “If I lived down there, even closer than I do, I'd be really worried about it. The vibrations must have a huge impact. The building cannot be stable. There's no infrastructure inside to maintain, and I think that I'll be waiting for the kaboom in the dark of night.” — Linda Miller
