Dark ride

A dark ride or ghost train is an indoor amusement ride on which passengers aboard guided vehicles travel through specially lit scenes that typically contain animation, sound, music and special effects. Appearing as early as the 19th century, such exhibits include tunnels of love, scary themes and interactive stories. In its most traditional form, the term dark ride refers to ride-through attractions with scenes that use black lights, whereby visible light is prevented from entering the space, and only show elements that fluoresce under ultraviolet radiation are seen by the riders. The size of each room containing a scene or scenes is thus concealed, and the set designer can use forced perspective, Pepper's ghost and other visual tricks to create the illusion of distance. Typically, these experiences also use a series of opaque doors between scenes to further control riders' views within a space-constrained building. Prominent examples include Disneyland's Snow White's Scary Adventures, Pinocchio's Daring Journey, Peter Pan's Flight, Mr. Toad's Wild Ride and Alice in Wonderland, which all rely on the use of blacklights in almost every scene. The first dark rides appeared in the late 19th century and were called "scenic railways" and "pleasure railways". A popular type of dark ride commonly referred to as an old mill or tunnel of love used small boats to carry riders through water-filled canals. A Trip to the Moon began operation at the 1901 Pan-American Exposition. Marvin Rempfer and Leon Cassidy of the Pretzel Amusement Ride Company patented the first single-rail electric dark ride in 1928. Historically notable dark rides include Futurama at the 1939 New York World's Fair, and Pirates of the Caribbean and The Haunted Mansion at Disneyland. Modern attractions in this genre vary widely in technical sophistication. Smaller-scale rides often feature the same sorts of simple animation and sounds used since the genre's early days, while more ambitious projects feature complex animatronics, special effects and ride vehicles utilizing cutting-edge technology.
