Westbound between Detriot and Grand Rapids on CSX's Plymouth Sub, train Q327 crosses the Thornapple River Bridge near Whitneyville, MI on a beautiful late summer day. Led by an ex B&O GP38 still in Chessie System colors and a former L&N C30-7, the train will soon be changing crews at the CSX (C&O, Pere Marquette), Wyoming, MI yard before proceeding to Chicago .
