This flange adds to the lateral stiffness ofthe joint and keeps the track in better alinement. In this country the an°le-bar joint will probably continue to be the standard for the lighter track, but forfirst-class heavy track it is often supplemented by a base support to the rails, asnoted below. In some of the older joints, the outside bars extended along the side of the railhead, but this practice has been abandoned. The bars should be so designedand proportioned as to make the joint a

In some of the older joints, the outside bars extended along the side of the railhead, but this practice has been abandoned. The bars should be so designedand proportioned as to make the joint as strong and stiff as the body of the rail,but many joints are defective in stiffness to resist slight deflections. The barsare usually of uniform section throughout, but sometimes have the thickness ofthe web increased at the middle by tapering from the ends or by flange sometimes extends only about |-in. beyond the rail base, or barelyenough to give a hold for the slot spikes, as in B, Fig. 42; in such case, these. 4(JnderHead-*
