I originally posted this information on my old website on March 26, 2009, and last updated it on December 18, 2009.
There were three wig-wags on Portland's former Southern Pacific Willamette Shore Trolley line, though now only two remain.
They have uniquely-painted banners seen nowhere else, proclaiming a "Trolley Xing." This one on Riverwood Road is the southernmost one.
The video below shows the Willamette Shore Trolley at the Riverwood Road wig-wag.
North of the Sellwood Bridge on the former Southern Pacific Willamette Shore Trolley line is this railroad crossing leading to the Macadam Bay Yacht Club and Butterfly Park.
At this crossing another wig-wag stands guard with its unique banner.
This wig-wag is plainly visible from SW Macadam Avenue/Oregon Highway 43.
This wig-wag stood on the Willamette Shore Trolley's former Southern Pacific line at the Nebraska Street crossing near the entrance to Willamette Park.
It was struck by a vehicle in early 2008 and had to be removed.
A member of the trolley crew must now manually flag the crossing.
The banner shaft of this crossing was decorated with the text of Proverbs 15:3, "The eyes of the Lord are in every place beholding the evil and the good." in tiny lettering.
The banner was still painted in an earlier "Stop for Trolley" paint scheme.
This operational wig-wag is located at the Oregon Zoo in Washington Park on the 30-inch-gauge Washington Park & Zoo Railway, protecting a zoo service road.
It was almost certainly originally located at a public railroad crossing somewhere else and moved to the zoo later.
It is stenciled "CM 733.7," a milepost which would seem to place it on the Southern Pacific Railroad somewhere in Oregon, though I'm not sure where. I would guess Dallas or McMinnville.
The banner has an odd paint scheme of a red cross (instead of a narrower black one) and no border.
This wig-wag is on static display outside the home of the Columbia Gorge Model Railroad Club, at 2505 North Vancouver Avenue.
