Electrical Experimenter (08:03) July 1920

Hugo Gernsback, editor

"A medium weight train can be operated at high speed over the suspended monorail system with the same stability as at present obtainable only by the use of very heavy trains with their low center of gravity. The big point here, is that with our heavy trains, we continually need more horse-power to move them, and more speed means more weight. This is not the case with the suspended monorail train, it being possible to operate it at from 70 to 80 miles an hour with only medium weight in the cars."
Electrical Experimenter July 1920 magazine cover
