A Museum Is Only As Strong As Its Members. On Saturday, October 9, 2021, as part of the Friends of the East Broad Top 2021 Fall Reunion Weekend, the Rockhill Trolley Museum had a strong showing from its membership as it staffed multiple trolley trips per hour, food concessions, and tours of the grounds. Johnstown double-truck Birney 'safety car’ 311 (1922, Wason) in the background is a local veteran, restored to operation in recent years after a complete restoration.
