We are used to see these moving plattforms on the airports.
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.
