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.

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.

A process for producing a coupler and an improved coupler are provided. The process produces a coupler by constructing a mold that is a replica of the coupler and is constructed from a plurality of mold components that are selected and assembled to form a mold having the shape of the coupler. The mold components may include a front mold component section that forms the head of the coupler, a rear mold component section that forms the shank of the coupler, and, optionally one or more shelf components forming a shelf of the coupler. The front, rear and shank mold components may themselves be made from a plurality of mold components that are assembled together. The mold is formed from a consumable material, coating with a heat resistant material so that the assembled mold components are within a mold volume, and molten metal is added to the mold volume.

A claw system for mechanical coupling a railcar mover to a railcar is disclosed herein. The claw assembly may comprise a set of arms and a set of claws each mounted on the interior side of one of the set of arms. When a railcar adjacent to a railcar mover on a set of tracks is positioned within a proximity of the railcar mover, the claw assembly may be utilized to grasp the air hose of the adjacent railcar. For example, the set of arms may be attached to the railcar mover via a motorized rail upon which the set of arms may be configured to move axially toward each other in a direction perpendicular to the tracks, thereby causing the claws to move toward each other and close around the air hose of the adjacent railcar. The claws may include openings configured to grasp the air hose.
