The Jupiter and Lake Worth Railway was a 7.5-mile (12.1 km) connection between the Jacksonville, Tampa and Key West Railway system. It connected Lake Worth at Juno, Florida to Jupiter Inlet at Jupiter, Florida. With intermediate stops at Venus and Mars, it was often called the Celestial Railroad.
Both Lake Worth and Jupiter Inlet had Plant System steamboat lines. The Indian River Steamboat Company went north through the Jupiter Inlet and connected waterways (now part of the Intracoastal Waterway) to Titusville.
There were no turning tracks, so the locomotives always pointed towards Juno, forcing trains making the return trip to go in reverse.
