Engine House Tours: Golden Spike National Historic Site is home to the steam locomotives Jupiter and No. 119. These engines are fully-functional replicas of the original locomotives that met here on May 10, 1869, for the "Wedding of the Rails" ceremony. These locomotives do not run during the winter season, but they are on display in the Engine House.
