Abstract: An articulated railcar for transportation of highway trailers is lightweight and has a deck height which permits heavy highway trailers to be carried without exceeding the maximum allowable center of gravity height above the top of the rail.

Abstract: The tank of a railway tank car is supported adjacent to its opposite ends on two truck-mounted underframes, each underframe including a pair of body bolster plates disposed in a plane substantially perpendicular to the longitudinal axis of the tank and having an upper edge spaced well above the associated truck. Cover plates extend along the outer edges of the body bolster plates substantially perpendicular thereto and projecting upwardly above the upper edges thereof. Each body bolster plate has a rectangular notch in the upper edge thereof spaced closely adjacent to the outer surface of the tank. A lifting lug extends along each upper edge from the cover plate to the slabbing to close the upper end of the notch and define an opening to receive an associated lifting lug. Each lug has a broad inner end against the tank slabbing.

Abstract: A lift lug for receiving and securing a lifting device to a railroad tank car for re-railing the tank car. The lift lug includes a bolster pad mounted adjacent an end of the tank car and a vertically disposed bolster web, the bolster web having a substantially horizontal extending upper edge. A substantially horizontal base plate is mounted on the extended upper edge of the bolster web with an inner edge of the horizontal base plate secured to the bolster pad. A substantially vertical lift lug plate has its upper edge secured to the bolster pad and its lower edge secured to the base plate. A pair of generally triangular lift lug webs each have their lower edges secured to the base plate, their outer edge secured to the bolster pad. The lift lug plate has an opening adjacent its lower edge.

Abstract: A roping staple (and lifting lug) especially for securing to the side sill of a railroad car. The roping staple is uniquely provided with the strength and accessibility required for modern day railroading and yet is suitable for economical construction.

Abstract: An attachment for a fork lift truck for opening and closing sliding doors such as railway freight car doors. The attachment includes a floor that can be engaged by the tines of the fork lift and two vertically spaced apart door engaging members mounted to the floor for transverse movement with respect thereto. The floor also mounts an upstanding cage assembly so that a person can work inside a protected area.

Abstract: An attachment for a fork lift truck that facilitates opening and closing of railway freight car doors. The attachment includes a base plate which pivotally supports a push arm at each side thereof that is connected to means for providing a controlled shock absorbing pushing force to the door so as to prevent damage thereto.
