The original Museum collection consisted of equipment used by the former United Railways and Electric Company and Baltimore Transit Company (BTCO) services, which was held for a short time, the Maryland Historical Society after Baltimore ceased streetcar service. The collection was moved from what was at the time Robert E. Lee Park, near Lake Roland, in 1968 to the present Falls Road Maryland and Pennsylvania Railroad site and public operations began in July 1970. Before public operations could commence, many hours of volunteer work were necessary to build operating track and install overhead wire which, at first, provided only a short ride for visitors.
