Built in 1919 in Pennsylvania for the United States Navy, it was used in New York. The Brooklyn Eastern District Terminal started in 1906 for maritime operations and needed six standard-gauge switcher locomotives and eleven miles of tracks. This locomotive was sold to the Brooklyn Eastern Terminal District in 1922. This area was the last to operate steam locomotives in New York State when they were replaced with diesel-electric locomotives. The railroad was used for another twenty years. #12 was purchased by a man named Ron Ziel for $900 to pull excursion trains on the Sag Harbor and Scuttle Island Railroad, where the Long Island Railroad used to own a branch line. Long Island Railroad abandoned this line during the 1930s. This did not happen, unfortunately. So, #12 was on a siding in New Jersey for many years. Robert Most from Florida purchased #12 in 1971, and it was donated to its current location, where it is now on display at the Florida Railroad Museum, in 1982.
