The "Big Boy [steam locomotive] will travel across 14 states during its historic tour from California to New York, with a two-day Fourth of July stop in Philadelphia, the birthplace of America."

"Big Boy No. 4014 is the world’s largest operating steam locomotive, weighing 1.2 million pounds and 133 feet long – which is a little over half the length of a Boeing 747. It was one of 25 commissioned by Union Pacific in the early 1940s to haul large volumes of freight over the Wasatch Mountains in Utah."
