Back in my Pentrex Publishing days (in the mid 1990s) I wrote an editorial about the ultimate demise of the searchlight signal.
Even then, this style of hardware was out of favor for new installations, yet thousands of the old signals still remained.
Today they are fast disappearing, and at many installations they are already gone.
Two weeks ago, when traveling with Bob Arnold and Paul Goewey, we opted to photograph an outbound MBTA train passing these General Railway Signal searchlights on the old Boston & Maine west of Ayer, Massachusetts
I wanted to feature one of the new HSP-46 diesels passing the vintage signals to show the contrast in technology. The window for making this type of photograph is rapidly narrowing, as these searchlight’s replacements are in place and will soon be cut in.
My book Classic Railroad Signals, published by Voyageur Press, details many varieties of older signal hardware and tells the story of American signaling with stunning photographs and detailed historical information. Get your copy today!
