Modifying the Lionel 6-15067 Southern Pacific 4 bay hopper. Road number is SP 306401
This model is a very basic O-27 4 bay hopper that was issued in 2012. It was produced by Lionel LLC, Chesterfield, Michigan.
Since the hopper did not have a top "cover" a custom made gravel "load" was added. Also the supplied brake cylinder was replaced by custom made brake equipment.
