El Gobernador

El Gobernador was an American 4-10-0 steam locomotive built by Central Pacific Railroad at the railroad's Sacramento, California shops. It was the last of Central Pacific's locomotives to receive an official name and was also the only locomotive of this wheel arrangement to operate on United States rails. At the time it was built, El Gobernador was the largest railroad locomotive ever built. Its name is reminiscent of the railroad's first locomotive, Gov. Stanford, as El Gobernador is Spanish for The Governor. This locomotive is a Mastodon type. Confusingly, this was the unofficial name for an earlier engine, "Mastodon" No. 229, the first successful 4-8-0 ever built. Both engines looked nearly identical, except that El Gobernador was longer and had an additional pair of drivers.
