Abstract: A rail vehicle sectioned door assembly for a door opening having a stairwell. The assembly comprises a sliding door having a door upper section and lower section slidingly interconnected together by a lock assembly. The door lower section is provided with guide rails to position same adjacent the stairwell. A stairwell platform is hingedly connected to one side of an upper horizontal plane of the stairwell. The platform is releasably secured in a retracted position clear of the upper horizontal plane and the stairwell. The platform is displaceable to lie in the horizontal plane, in a position of use, and is supported thereon. The lock is disengaged by the platform when displaced to its position of use to disconnect the door upper section from the door lower section whereby to permit the upper section to slide open while the lower section closes a lower portion of said opening below the platform.

Abstract: A railway car underframe includes a sill structure having at one end a cushion pocket disposed rearwardly of a draft structure which is readily adapted to support a drawbar assembly having at its rear end an impact head extending into the pocket and engaging a cushion. The cushion is spaced from one end of the pocket by a removable spacer assembly which is removed when a larger cushion is disposed in the pocket and a shank coupler assembly is utilized. The draft structure includes attaching means to which a bell mouth housing is removably secured when the coupler assembly replaces the drawbar assembly. The structure includes a member which is a combination having a draft lug function, for coupler application, and a draft keyslot function for drawbar application.

Abstract: A railway car underframe comprises a center sill having bell mouth draft housings at opposite ends thereof. The housings accommodate the use of drawbars or shank type couplers. With the use of a shank type coupler a draft housing extension is secured to the bell mouth housings. The housings include structural shear elements interengageable with each other to align and secure the housings in rigid relation. The housings include connector plates secured together by fasteners with said connector plates longitudinally spaced apart to provide vertical spaces. Wedge elements having open end vertically spaced recesses are driven into the vertical spaces to provide for rigid metal to metal contact with the spaces accommodating the fasteners. Proper alignment, securement, and quick assembly therefore is achieved.
