The Central Pacific No. 63, named The Leviathan, is a 4-4-0 American steam locomotive. It was built by the Schenectady Locomotive Works of New York in September 1868 for the Central Pacific Railroad, and was used for the Transcontinental Railroad project.
The engine was designed to haul passenger trains for the Central Pacific Railroad including transports to build the First Transcontinental Railroad.
Sadly, the historical significance of this locomotive was not realized until decades after it’s scrapping in the early 1900s. By then, the Leviathan had been unrecognizably altered.
In 2009, a replica was made; the replica remains operational today but only operates on special occasions and is also used for tourist excursions of any kind. But as of today, the Leviathan has been moved to the Star Barn Estates in Elizabethtown, PA. It is currently unknown if the locomotive will be traveling anymore. When the Leviathan moved to the Star Barn Estates, she was also relettered and renumbered as "Pennsylvania Railroad No. 331".
