City transportation idea for NYC: Rapid transit by belt conveyor (1910)
The method of transportation by moving platform shown can carry, according to the Public Service Commission, 73,500 people per hour at 12 miles per hour. Up to distances of 4 miles, this is as fast as travel by the present combined express and local service.
The express trains can carry 36,000, and the local trains 22,500 per hour. The successive platforms move at 3, 6, 9, and 12 miles per hour. – A vision of the future, as published in Scientific American in 1910 / Illustrator: Beverly Towles / Courtesy the NY Public Library
Moving sidewalk for New York (1910)
The property owners on 34th Street recently held a meeting, and by a decided majority, voted in favor of constructing a moving sidewalk in that cross-town thoroughfare.
A company has been organized to build the new magnetically-propelled carriage, and complete working models have been constructed.
Above is a section of the model and its method of operation. Benches are installed on the fastest-moving platform.
Shown is a section of the complete arrangement, with the three moving platforms. The slots marking the connection point between the sections out of which the device is made can be easily seen. Each section is approximately six feet in length. The floors are made of wood, the frames of fabricated steel. – Science and Invention magazine, 1923
