The Oregon Department of Transportation purchased several RDC-1s from BC Rail and plan to use them on an excursion train (over 90 miles one way) between Portland Union Station and Astoria - at the mouth of the Columbia River into the Pacific - for the Lewis & Clark Celebration.
AND...the Pacific Northwest Chapter of the NRHS owns two demotored RDC-9s which are used in occassional excursion service.
