The 65ton GE was trade to a person in Michigan and then it was either traded or sold to the Ohio Central in 2004.

I looked at the satellite image of the National Railway Museum (Green Bay) and their loop track is a curious arrangement. It has two bridges, one of which looks expensive to maintain for such a small length of track. How did they end up with such a setting?

I also note the proximity of residential housing. Do they have issues with noise and smoke complaints?
