  • Patent number: 3934515
    Abstract: A transportation system is comprised of a first closed loop passenger and cargo transporter section with such section being ideally intended to operate at a substantially constant speed, and a second closed loop passenger transfer section with such section being intended to operate, generally between the first closed loop and a related stationary passenger platform, as to cyclically maintain a speed equivalent to the constant speed of the first closed loop, then decelerate until it is stationary with respect to the related stationary passenger platform and then accelerate until it is again at the speed of the first closed loop transporter section. Passengers and cargo may, during the time that the transfer section is stationary with respect to the passenger platform, transfer from the platform onto the then stationary transfer section (or if getting off of the system, transfer from the then stationary transfer section onto the platform).
