This photo was taken from an inbound Red Line
train just as it passed over the track that that train had been on moments
before. This is likely the only location in the country where both
directions of a light (or heavy) rail route cross over the same line below.
Portland International, trains perform a slow, long, counterclockwise loop behind the camera
to get up from the short, single-track
portion below onto the original MAX line. Switches and three tracks
Gateway/NE 99th Ave. Transit Center allow light rail runs to be sorted out properly.
