(Portland, OR) -- Officials say an electrical vault fire that broke out in a downtown Portland apartment building knocked out the building's power and forced area MAX lines to close temporarily. Portland Fire & Rescue spokesman Lieutenant Rich Chatman tells "The Oregonian" the fire started in the basement of the building in the 16-hundred block of Southwest Morrison Street around 6:45 last night. The four-story building was safely evacuated and firefighters extinguished the blaze. Power to the building was out for several hours and shuttle buses were used to replace downed MAX lines.
