Abstract

Two central railroad tracks, carrying express trains in opposite directions, are flanked at a station by respective pairs of lateral tracks accommodating shuttle trains for the loading and unloading, respectively, of the associated express trains. The shuttle trains accelerate from standstill, upon the approach of the express train, to the speed of the latter and, on pulling abreast with the express train, dock with it to facilitate the transfer of passengers and freight from the loading shuttle to the express and from the express to the unloading shuttle. The freight compartments of the trains have lateral door sections which, for docking as well as loading and unloading, can be swung down and up to form bridges with guidetracks and overhead bearing surfaces for roller-mounted transporters which are pneumatically shifted across these bridges.

Claims

1. A rapid-transit system comprising:

a plurality of stations each including a loading platform and an unloading platform;

a rail link for said stations including at least one main track passing between said platforms;

a first and a second ancillary track flanking said main track at least in the region of each station;

an express carrier on said main track moving at a substantially constant speed past said stations;

a first shuttle carrier on said first ancillary track for loading said express carrier at a location downstream of the loading platform of a station, said first carrier being accessible from said loading platform and being accelerable from standstill at said loading platform to the speed of said express carrier for pulling alongside same and docking therewith temporarily at said downstream location to facilitate transfer of its load to said express carrier, followed by undocking and deceleration to standstill; and

a second shuttle carrier on said second ancillary track for unloading said express carrier at a location upstream of the unloading platform of a station, said second shuttle carrier being accelerable from standstill to the speed of said express carrier for pulling alongside same and docking therewith temporarily at said upstream location to facilitate transfer from said express carrier of some of the load thereof, followed by undocking and deceleration to standstilll at said unloading platform for discharging the transferred load thereat.

2. A rapid-transit system as defined in claim 1 wherein said main track forms a closed loop.

3. A rapid-transit system as defined in claim 2 wherein said shuttle carriers are reversible on said ancillary tracks for reciprocation between respective upstream and downstream terminals, the upstream terminal of one of said ancillary tracks being disposed alongside said loading platform, the downstream terminal of the other of said ancillary tracks being disposed adjacent said unloading platform.

4. A rapid-transit system as defined in claim 3 wherein said loading and unloading platforms of a station are relatively staggered along said main track, said ancillary tracks being substantially coextensive with each other and of sufficient length to enable substantially simultaneous docking of said shuttle carriers with said express carrier along a stretch intermediate said loading and unloading platforms.

5. A rapid-transit system as defined in claim 1 wherein said carriers are provided with freight compartments aligned with one another during docking thereof, said freight compartments being provided with doors retractable for docking, at least some of said doors having sections swingable from one carrier to an adjoining carrier to form bridges for wheeled freight transporters receivable in said compartments.

6. A rapid-transit system as defined in claim 5 wherein said bridges are provided with guidetracks for the wheels of said freight transporters.

7. A rapid-transit system as defined in claim 5 wherein said compartments are provided with upper guide surfaces for said freight transporters, at least some of said doors having other sections swingable from one carrier to an adjoining carrier to form overhead bearing surfaces at the level of said guide surfaces for said freight transporters.

8. A rapid-transit system as defined in claim 5 wherein said compartments have lateral walls provided with arrays of coplanar rotating bodies engageable with said freight transporters for stabilizing same.

9. A rapid-transit system as defined in claim 5 wherein said compartments are provided with fluid-actuated thrust means for transferring said freight transporters from one carrier to an adjoining carrier.

10. A rapid-transit system comprising:

a rail line with three parallel tracks including a central track and two lateral tracks;

a continuously running passenger carrier on said central track;

a pair of intermittently moving shuttle carriers on said lateral tracks; and

several stations each forming a loading platform alongside one of said lateral tracks and an unloading platform alongside the other of said lateral tracks, said unloading platform lying downstream of said loading platform in the direction of movement of said passenger carrier;

said loading platform giving access to one shuttle carrier upon a halting thereof at the station for boarding by waiting passengers, said unloading platform being accessible to arriving pasengers on the other shuttle carrier upon a halting of the latter at the station, said shuttle carrier being accelerable to the speed of said continuously running carrier and being provided with docking means for temporarily and substantially simultaneously locking onto said continuously running carrier along a stretch located intermediate said loading and unloading platforms to facilitate the transfer of passengers therebetween.
