Kelley Park in San Jose CA brings together a unique mix of relocated and replica historic buildings, and a working trolley line, to help tell the story of the City's early history. For many years the park employed master trolley restorer Fred Bennett, whose craftsmanship helped bring several "chicken coops" (including this San Jose Railways Birney car) back to life as working trolleys.
Here's an old 1984 video on the Kelley Park trolley story, Fred Bennett appears starting at the 13:50 mark:
