  • Patent number: 4522546
    Abstract: A railroad station with at least two main tracks for freight trains with container-carrying flatcars has several pairs of ancillary tracks each flanking a respective main track, the ancillary tracks being used by respective sets of self-propelled transfer vehicles each having a length substantially corresponding to that of a flatcar. Each transfer vehicle is divided into four identical sections having respective pairs of transport arms which are laterally extendable in either direction to support containers of full or fractional lengths to be moved from or onto a flatcar, another transfer vehicle or a road vehicle aligned therewith. The spacing of the transport arms of each pair differs between vehicles on neighboring ancillary tracks to enable their extension into an interleaved position for a transfer of a container therebetween.

  • Patent number: 4093084
    Abstract: A rail network serving a given territory has a multiplicity of transfer stations for the transshipment of freight containers between local truck routes and scheduled freight trains, as well as between trains traveling to different destinations, each train comprising a number of flatcars with transverse roller conveyors which are aligned with similar conveyors on adjoining platforms when the train halts at a station. The platforms are separated by one or more railroad tracks and by several longitudinal conveyors in the form of articulated chains whose links are also provided with transverse roller conveyors alignable with those of the platforms and the flatcars. Transversely shiftable platform sections, each of a length equaling that of the flatcars, can be advanced into contact with a standing train to complete a driving circuit for the flatcar-mounted conveyors whereby containers resting on the rollers of a platform section can be moved onto the flatcar or vice versa.
