Abstract
Abstract A continuous transport system for trains with programmed vehicles. The system comprises at each station a connection track (H10, H20, H11, H21, H13, H23) linking the outward track (OX) to the return track (X''O'') or conversely, to enable a train travelling from a high density traffic area to a less dense traffic area, to reduce the number of its vehicles and, to enable a train travelling in the opposite direction to recover vehicles. The system for transporting persons comprises a minimum number of vehicles to ensure maximum flow.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
107 words
A track transport system for trains with programmed vehicles comprising a principal outward track and a principal return track, contiguous station platforms located between the tracks respectively for passengers leaving the outward and return trains, and respective connecting tracks of cissoid shape, one connecting track joining the outward track to the return track while servicing one of the passenger platforms and the other connecting track joining the return track to the outward track while servicing the other station platform, characterized in that each connecting track has a section enabling the train to approach its station platform from one direction while leaving the platform in the opposite direction.
Claim 2
Dependent Claim
107 words
A track transport system for trains with programmed vehicles comprising a principal outward track and a principal return track, contiguous station platforms located between the tracks respectively for passengers leaving the outward and return trains, and respective connecting tracks of cissoid shape, one connecting track joining the outward track to the return track while servicing one of the passenger platforms and the other connecting track joining the return track to the outward track while servicing the other station platform, characterized in that each connecting track has a section enabling the train to approach its station platform from one direction while leaving the platform in the opposite direction.
Claim 3
Dependent Claim
24 words
A track system according to claim 1 where the connecting tracks are of disjointed cissoid form, each having a reversing terminus adjacent its platform.
Claim 4
Dependent Claim
49 words
A track system according to claim 1 where the connecting tracks are of cissoid form are joined so that trains can pass from one connecting track to the other, or can be reversed at the platforms or can be shunted back to the principal track where the train originated.
