Caption: A dismal winter afternoon, even though this a color image might as well been black and white film. Train symbol MC-4 with a trio of F units and a U boat all elephant style running east on the double track CASO is about to bang over the diamond of the single track TH&B Dunnville sub. E&O tower was located at mile 30.5 on the Penn Central Canada Division CASO. A "Kodak Instamatic Moment" from long ago.
