Seeing those two tunnels stacked with the station on top made me think they were a building until I zoomed in. I don't recall seeing a different variant of the metal bell crossing where the base is wider and the signal box faces the track. It looks a bit better than the one I'm familiar with and have one of, so I'd like to know what set comes with it. Are the big grey risers meant for that cyan straight with the walls? The wide trim around the bottom doesn't make them look good for stacking. Looking forward to seeing your plans for the garage once the conditions get better.
