|Although the photo is damaged near the pilot and front, it still shows an impressive 1935 Alco-Schenectady built small 4-8-2 Mountain type locomotive used by Bangoor & Aroostook. These relatively small Mountain type locos with small drivers were for low-speed freight hauling. Specs - class M, 62" drivers, impressive 240 psi boiler pressure, 22.5x30" cylinders, engine weight of 317,490 lb, tractive effort of 49,972 lb. The entire M class of 10 was retired between 1950-53 with none preserved. Date and location are unknown but it very well may be at the North Maine Junction yard near Hermon, ME as most 4-8-2's were serviced there. Unknown photographer.
