The Kings Island & Miami Valley Railroad is a 3 ft (914 mm) narrow gauge heritage railroad and amusement park attraction located at Kings Island in Mason, Ohio.

The entire journey lasts between 9 and 15 minutes, depending on station stops and number of trains in operation.

New changes were added to the ride’s scenery (most notably a refreshed western town, as well as new animals that occupy areas within the forest).

The Kings Island & Miami Valley Railroad maintains two working locomotives.

They were built by Crown Metal Products of Pennsylvania for the park opening in 1972 and were modeled after The General.

Originally, it featured a balloon-style stack but it was replaced in the late 1980s or early 1990s to make it stand apart from the green engine.

The engine is painted green and was originally named Simon Kenton, after a famous Ohio frontiersman.

The Kings Island & Miami Valley Railroad features two train stations.

The Front Conductor is in the charge of the movement of the train, as well as the entertainment and wellbeing of the passengers aboard.

During a normal passenger loading procedure, the station master must clear the station platform with a thumbs up signal, at which point the Back Conductor must clear the Front Conductor for movement with a hand signal known as a "Highball".

The Kings Island & Miami Valley Railroad operates during the entire season.

When Kings Island began construction of Mystic Timbers in 2016, the exit path was shortened significantly, and Tombstone Terror-Tory was removed from the Halloween Haunt lineup.
