    Abstract: The present disclosure provides a curve portion mold structure for manufacturing a curved concrete panel for a mountain railway rack track and a curved concrete panel manufacturing method using the same in which, by forming a curve portion mold structure made of an outer mold and an inner mold to manufacture a curved concrete panel for a mountain railway rack track, the curvature of the outer mold and the curvature of the inner mold can be simultaneously adjusted, and a curve can be implemented by a difference in pressure introduction of a screw jack at a side surface of the outer mold. Also, by dividing a bottom plate of the outer mold to form the bottom of the curved concrete panel, application to various forms of curvatures of the curved concrete panel is possible, and by implementing a curvature by coupling between blocks using a fastening pin in an inner mold made of an intermediate block, an end block, and an impact-absorbing block, the curved concrete panel for a mountain railway rack track can be easily manufactured.

    Abstract: A system for exclusive track resource sharing is provided. Some embodiments provide an exclusive track resource sharing system including onboard control units and a resource manager. Onboard control unit is provided in each of trains and is configured to communicate with another onboard control unit in another train. The resource manager is configured to record ownership status information of track resources of the plurality of trains, to provide the ownership status information of the track resources to the onboard control unit, and to generate and deliver a resource entitlement or resource authority to the onboard control unit. The resource authority is configured to be owned by a single onboard control unit. The onboard control unit possessing the resource authority is configured to seize or release the track resources corresponding to the resource authority and to control the track resources corresponding to the resource authority.
