I was out railfanning at Delaware, OH today and saw this. At first glance, I thought the gates were just in the process of being replaced, and the old one hadn't been removed yet. But then I noticed not only how new these were, but saw the old ones laying not far away. There is some kind of small CSX service facility right next to this crossing. Could it be that the smaller gate is for the sidewalk, and pedestrian traffic? I've never seen anything like this before.
