Compressed air train – AIR PUNK!
Will steam power give way to compressed air for driving locomotives and hauling fast passenger trains? That is the vision of William E. Boyette, of Atlanta, Ga., whose amazing challenge to the iron horse—a monster truck-shaped locomotive propelled by compressed air—was about to undergo a trial run between Atlanta and Jacksonville, Fla., at this writing. The forty-foot locomotive, illustrated above, is designed to attain a maximum speed of 125 miles an hour. Its power is obtained from air compressed to a pressure of 400 pounds to the square inch and carried in tanks behind the cab. Should the pressure in the tanks drop below 360 pounds, a pump operated by electric storage batteries automatically replenishes them. Besides high speed, Boyette claims the advantage of exceptional economy in operation.
