Gaithersburg Community Museum 9 S Summit Ave, Gaithersburg, MD20877 The Gaithersburg Community Museum dates back to 1884, when the building served as a B&O Railroad station. Today it…More sits in the heart of Olde Towne, just feet from the still-active CSX rail lines and a working train station. The building was added to the National Registry of Historic Places in 1978. It features a rolling stock exhibit of a 1918 Buffalo Creek and Gauley #14 Steam Locomotive, a C&O Railroad Bay Window Caboose, and a circa 1940 Defense Transportation Corps Troop Kitchen Car. A working scale train model is located in the museum as well. But the museum's focus is on the whole history of Gaithersburg, not just its railroad-tied past.
