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.
