Stumbled across this odd little railway on one of the freight industry Journals, would make an ideal micro layout for some one who is VERY space limited.. Consists of about 100ft of track with a road/rail tractor and two flat cars.. But is is fully functional and due to a strange quirk in the US Jones act it serves a commercial purpose!
