Abstract:
Systems and methods for sensing a train position of a train with no internal drive operating in an automated train system are provided. According to one embodiment, a train system comprises a track extending in a travel direction, a plurality of cars riding on the track and connected to form a train, a position sensing unit, and a programmable logic controller (PLC) in signal communication with the position sensing unit and configured to determine a train position based on inputs therefrom.
Abstract:
The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes improvements in functionality, manufacturability and/or modularity and, therefore, can result in a reduction in system component costs, manpower and/or implementation. The rail transport system includes a dump loop and components thereof for enabling unloading of the rail cars in a predetermined location. The components thereof may be designed to be modular to allow for ease of manufacture and installation of the dump loop. The components may be prefabricated for later use on site.
Abstract:
The present invention generally relates to support frames and rail cars comprising first and second side drive plates, first and second cross members connecting the respective ends of the side drive plates, third and fourth cross members connecting the side drive plates at a select distance from the first and second cross members, a coupling assembly situated at the first cross member and adapted to connect another rail car thereto, and first and second diagonal support members connected to the first cross member at an angle sufficient to substantially direct forces from the coupling assembly to the third cross member and side drive plates. The support frames and rail cars may be used for conveying bulk materials on a rail transport system.
Abstract:
The present invention generally relates to a rail transport system having no internal drive, and in particular to an improved rail transport system for conveying bulk materials. The rail transport system includes horizontal and vertical drive stations that include a drive tire that rotates on a plane parallel to the track. In this arrangement, force is applied on a different plane than earlier systems, and the reaction force is separated out of the tensioning device. The improvements of the drive stations provide for a reduction of steel used in the system, improved manufacturability and, therefore, reduction in system component costs as compared to previous drive stations. Moreover, the drive stations allow for improved maintainability and access to the drive tires.
