The Marker Light was the name of the Port Huron & Detroit Railroad Historical Society’s (PH&D RRHS) quarterly newsletter. It was put together and published by George Y. “Sandy” Duffy Jr., one of the Society’s founding members and longtime Society President. The Marker Light served to keep Society members (and some benefactors) up to date on Society activities and as a source of information about the PH&D and how it had operated. There were several interviews with former employees included in its pages.
Because the PH&D RRHS was dissolved a couple years ago, back issues of the Marker Light are no longer available for sale. At different times, digital copies of the current Marker Light issue were made available for download from various sources.
Altogether 45 issues of the Marker Light were printed over 13 years. All 45 issues will (like everything else on this website – eventually) be available for download on this page. Files are a mix of original digital downloads and scanned originals.
