Possibile, The CSX Here on the detroit and toledo, always are carrying some type of CP or CR, or "canada" type car, may it be on a westbound (Plymouth Diamond CP/CSX) carrying grain, or the Northbound boxcar, it was odd though. Never have saw that road signature till now. The CSX Plymouth Diamond has The C&O Northville Sub, Toldeo, and the CP detroit sub (TO WINDOR TUNNEL). Yu never know what you'll se in the Yard, going down I-96, however i have not seen a CP Caboose, a lot of old Chessie though, and a Conrail, one time.
