Here are some views I made the other evening at Tyters interlocking, west of Athol, Massachusetts, where the old Boston & Maine Fitchburg goes from two to one track westbound.
Intermodal train symbol 23K from Ayer, Massachusetts was heading into the sun.
Over the last few years Pan Am Railways/Pan Am Southern has replaced many of its old General Railway Signal searchlight heads with modern signal hardware. Yet some of the old signals survive, for now.
