Ends of two adjacent railroad cars may be joined by an articulating device when a series of such cars comprises a semi-permanent unit. The articulating device includes a male member which is connected to a sill of the first car and a female member connected to a like sill of the second car. Each connecting member has an inner end portion disposed within the respective sill. The structure of the inner end portion allows it to be joined to the sill by a select pattern of welds. These welds join the connecting member to the sill to form a connection therebetween which may withstand the high static and dynamic forces transmitted from the railroad cars to the articulating device during travel of the unit. |
