  • Staggered access to endless loop cable transit systems
    Patent number: 4270457
    Abstract: A method of access to a transportation system in which an endless cable pulls a series of transport modules in an endless loop is described. A single loop stops alternately at short and long intervals to combine in a single loop the advantages of separate local and express loops. The user combines the long and short distances, getting off and waiting if necessary, to get closest to his destination while making the fewest stops.
