Abstract
A connection or weld attachment and method are disclosed for use in connecting a first structural member with a second structural member. An end plate is preferably attached to one end of the first structural member. The end plate and first structural member may then be attached by mechanical fasteners and at least one weld to the second structural member. A railway car having an underframe defined in part by a pair of side sills and a plurality of crossties may be formed with this mechanical connection. The end plate may be attached to a first leg which is in turn attached to the respective crosstie. The first leg preferably increases in width extending from the crosstie to the end plate. The mechanical fasteners are preferably disposed at opposite ends of the weld to minimize possible fatigue cracking and to increase the life of the associated connection.
