Appears it was here, both poles for the mount still remain though the siren itself along with its mount are both long gone. Considering there's a railroad track right behind it, it's very likely this was the one you saw.
Looking at streetview, it appears that since that picture had been taken, the siren got a new gray coat of paint, and began to lean on its mount slowly over time. The siren lasted up to 2019 before meeting its demise.
Just a wolf, siren enthusiast and railfan.
