You’re looking at an October 1978 view of the sanding facility at Mechanicville, New York. Boston & Maine No. 1734 rests under this wooden structure that had to make the workers nervous to climb on. This would be a great modelling project for someone into that aspect of the hobby. Details abound including that MU hose hung on the side of the building and the coating of sand dust on the perch above the unit.
