A Great Northwest Railroad (GRNW reporting marks, a Watco Company) freight led by WAMX No. 3920 rolls across Union Pacific’s huge Snake River Bridge at Joso, Washington, on September 21, 2015. This local ran to UP’s Joso siding to pick up this train, and is crossing over GRNW’s Ayer Turn seen below the bridge. GRNW actually operated two Ayer Turns this day!
