Portland and Western's Harbor Turn Southbound (heading West SouthWest here) On old BN/SP&S tracks. She's moving about 10MPH heading for Banks Oregon where the power will swap ends of the train and take off on former SP tracks for Hillsboro and Beaverton where it will switch back to former BN/OE tracks and head for Tigard.
This was April 10, 2010's train.
