UP Resumes Rail Near Centennial Mills as Demolition Looms

Portland officials warned that resuming rail traffic near the deteriorating Centennial Mills warehouse, an eight-story structure with asbestos in debris, could trigger a collapse within a 150-foot collapse zone. Union Pacific announced plans to restart service in the affected corridor, saying the move is needed to minimize regional freight and passenger disruptions, while agreeing to safety measures. City officials say they have limited authority to block private railroad operations and are seeking hazard mitigation plans, hazmat presence, reduced speeds, and ongoing monitoring as demolition works proceed. Demolition of the building is mandated for the owner by August 14, with ongoing site investigations and coordination between the property owner and city agencies. Residents and officials have expressed frustration over unclear timelines and perceived information gaps as trains resume, but authorities reiterate public safety and debris management take priority. The site remains an active investigation area as work continues.
