In late July, (7/31/17 to be exact) I went with a friend to railfan the Columbia River Gorge, and one of the places we stopped at was Ruston Way in Stevenson, Washington. While we were waiting for a train to pass, I happened to get a picture of the siren that is still there. A Federal Signal Thunderbolt 1003 siren. I'm wondering if it's possible to see it in use, and if there just so happens to be any videos on the siren in particular. Also, are there any other Thunderbolts hidden in the Gorge on either the Oregon or Washington side (Longview and Yakima I already know about) that aren't very documented?
Oh, also, here's the picture:
