Does anyone know whether there was ever a trolley line in the vicinity of the old Poland Spring Hotel in Maine? A friend and I were exploring the area yesterday. We were looking for, and found, remnants of the old railroad spur that used to serve the nearby bottling plant; however, we were baffled by a long causeway over Lower Range Pond, adjacent to Route 26, that looked like it may have carried an interurban bed at one time.
