(Portland, OR)  --  Portland Fire & Rescue had a difficult time reaching a brush fire in North Portland Monday morning.  The fire was located along railroad tracks in the area known as "The Cut."  It's where North Fessenden [[ FESS'-en-den ]] crosses over the tracks.  A pile of railroad ties were on fire.  The flames spread to a nearby wooded area.  There are no roads near the tracks, so firefighters used ATVs to get hoses to the fire.  It was stopped before it could spread significantly.
