Boston & Maine GP9 1808 and local freight BO-1 out of Boston make their way through a late season snowfall, westbound outside Waltham, MA, on the former Fitchburg Division. The snow-covered track in the foreground is the abandoned Central Massachusetts Branch. The locomotive's 1800-series number indicates that it was one of the Geeps rebuilt in the early 1980s by the B&M's Billerica Shops .
