No one was injured Sunday when a Union Pacific freight train derailed at 11 a.m. in downtown Colfax and forced a temporary evacuation, the Department of Forestry and Fire Protection reported.
The evacuation was ordered because of initial concern that one of the five derailed cars may have carried a hazardous substance that was leaking. About 100 homes and downtown businesses were evacuated for several hours.
Union Pacific Railroad spokesman Aaron Hunt said the substance was listed on the train's manifest as being a saltwater preservative solution. Once that was confirmed by Placer County hazardous materials investigators, the evacuation was lifted.
Union Pacific late Sunday worked to return the derailed cars to the tracks, which were closed to all traffic. Freight trains were waiting in both directions for the tracks to reopen.
Hunt said workers hoped to reopen the tracks today.
