The John Bull is a steam locomotive that ran on the Camden and Amboy Railroad, the first railroad built in New Jersey. Retired in 1866, the locomotive was acquired by the Smithsonian in 1885 and became the oldest operable steam locomotive in the world in 1981, when it was operated in commemoration of the 150th anniversary of its first use. Though its official name was Stevens, crews began calling it John Bull, and the name eventually stuck. What made them choose that name? Discuss
