This past Saturday, I took a day for a railfanning trip with @SouthernIllinoisRailfan to Clark. In total, we saw 6 trains including this one. Canadian Pacific Kansas City train M258 (former KCS MKCVN) is a mixed freight from Kansas City, MO to Venice, IL that runs almost every day. This particular one had KCSM 4555 in trail, a "Gray Ghost" locomotive which are growing continuously more rare. This diamond in Clark is shared and operated upon by both NS and CPKC. It is always a treat to see a train here in town.
