Abstract
A rail car truck side frame has an upper compression member and a lower tension member, with these members being joined by integral end walls which slant upwardly and outwardly from the tension member toward the compression member. To protect the side frame from the elements of car progressors, there is a car progressor contact extending forwardly from the lower outward portion of each end wall of the side frame. The contact is formed and adapted to be contacted by and protect the side frame from the pusher of a car progressor. The car progressor contact may either be cast into the side frame or it may be a separate welded element. When the side frame is used in a frame brace truck, the car progressor contact may extend outwardly from the bracket which is attached to the side frame and supports the cross braces of the truck.
