High Quality Content by WIKIPEDIA articles! A moving walkway (British English) or moving sidewalk (American English) (colloquially sometimes travelator, horizontal escalator, walkalator) is a slow moving conveyor mechanism that transports people, across a horizontal or inclined plane, over a short distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction. The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the Paris Exposition Universelle in 1900. The walkway consisted of three elevated platforms, the first was stationary, the second moved at a moderate speed, and the third at about six miles an hour. These demonstrations likely served as inspiration for some of H. G. Wells' settings mentioned in the "Science Fiction" section below.
