A side sill arrangement in which a first channel member which forms a part of a side frame is joined to a second channel member which forms a part of the underframe assembly. The joined channel members form a hollow side sill beam assembly which extends longitudinally of the railway car to function as a strengthening member having sufficient strength to eliminate the need of a through car center sill. The formed beam includes hollow portions used to conceal fasteners which attach internal members thereby rendering the side sill with a smooth unobstructed outside surface permitting it to be used as an external member without additional covering.
