The Jupiter weighed 65,400 pounds and had 60 inch driving wheels and cylinders measuring 16 by 24 inches. The Jupiter was a wood-burning locomotive and generated a traction force of 10,790 pounds. Currently, an exact replica of the locomotive Jupiter, is located in the Golden Spike National, at Promontory Summit, Utah.
