Willamette & Pacific (WPRR) and it's sister railroad, Portland & Western, was formed in 1993 when they leased 185 miles of deteriorated track from Southern Pacific. They operate from Astoria - Portland - Eugene, Oregon. They are wholly owned subsidiaries of Connecticut-based Genesee & Wyoming Inc.
Although P&W supposedly operates the northern portion of the system, I observed only WPRR locomotives throughout the system and the only P&W logo I saw was on a crew facility in Eugene. WPRR was featured in Sept 2000 TRAINS.

WPRR 1801 at Eugene, OR, 8/04/04. W&P painted this single locomotive in SP's early diesel "Black Widow" scheme to commemorate it's original owner and W&P's heritage.

WPRR 2306 at St. Helens, OR, 8/03/04. W&P owns 17 of these former Santa Fe GP's (2301-2317).

WPRR 2317 at McMinnville, OR, 8/03/04, in Genesee & Wyoming paint.
