Moving sidewalkIn 1958, the first two-way, moving sidewalk, 1,425 feet long, was put in service at Love Field Air Terminal in Dallas, TX. It consisted of three loops. In each loop a continuous rubber carpet was attached to a continuous train of wheeled pallets, flexibly interconnected so they could follow vertical or horizontal curves as required. It was known not only as a moving sidewalk, but also as a passenger conveyor. |
