Portland Fire and Rescue says a fire at a transient camp led to a series of problems.
The fire Thursday near Interstate 205 and the airport caused a guy wire to snap and a utility pole to fall, bringing down high-voltage lines. The power lines fell on several cars and hung low over railroad tracks, blocking trains. Fluid leaked from an electrical transformer.
A hazmat team cleaned up the spill while a PP&L crew restored power.
There were no injuries. No one was found at the transient camp when firefighters arrived.
