When I studied the satellite imagery of the area, I noticed that there is a ramp near the track on the lot of Wisconsin Building Supply. I was surprised. I had not noticed it before. But I like the idea. This makes a great spot for a second car that can be delivered there.
To build the ramp, I took measurements in Google Earth. The ramp seems to be built of concrete. The wall pointing away from the track is higher as a safety measure to prevent fork lifts to drive off the ramp. Some steel plates are lying on or near the ramp to cover the gap between the ramp the rail car.
