the kings island & miami valley railroad operates during the entire season. throughout most of the season, it entertains guests and serves as transportation to and from soak city. during the park's annual halloween haunt event, which occurs on weekend nights in september and october, it was transformed into a haunted maze known as "tombstone terror-tory". the attraction had a western-theme and utilized the exit path of white water canyon. 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.
