Conrail BUOI passing an unusually tall semaphore near between Rathbone and Addison, New York. This signal once had a subsidiary arm that was dispatcher controlled and could be use to instruct a train to stop and ‘line in’ to the center siding at this location. In the steam era, Erie had center sidings at strategic locations to allow slower trains to get out of the way of faster ones, thus making more efficient use of its directional double track mainline. Lighting for this photo was unusual; the sun was just peaking out from heavy clouds and was slightly back lit, which helps accentuate the lens in the semaphore blade and illuminate the locomotive exhaust. It was 2 pm on April 16, 1988, and BUOI was beginning to accelerate after clearing a slow order. Photo made on Kodachrome 25 with a Leica M2 rangefinder fitted to a Visoflex with f4.0 200mm Telyt lens.
