The moving sidewalk was a very popular and useful attraction, given the large size of the Exposition. It consisted of a fixed platform and two mobile platforms, on a viaduct above the ground level, that covered a loop around the exhibition site with nine stations. The passengers stepped from the platform onto an access sidewalk wide traveling at , then onto a faster sidewalk wide moving at . The sidewalks had posts with handles which passengers could hold onto, or they could walk. The fast sidewalk made it possible to complete the loop in 26 minutes. The fare was an average of fifty
French franc centimes. The sidewalk went counterclockwise along the following
circle route: Esplanade des
Invalides along the Rue Fabert, Le Rue des Nations along the
Quai d'Orsay, the
Champ de Mars along the Avenue de La Bourdonnais and the Avenue de La Motte-Picquet to connect again with the Rue Fabert. It could simultaneously accommodate 14,000 people; during the afternoon of Easter Day, it carried 70,000 people, while the busiest tram and bus lines carried little more than 40,000 passengers a day on average. A
Decauville electric train followed the same route, running at a maximum speed of in the opposite direction to the moving sidewalk. The rail track was sometimes at 7 meters high like the moving sidewalks, sometimes at ground level and sometimes underground. ==Mechanism==
