A Bolted Rigid Frog is constructed with four rails that are specially fabricated from standard tee rails. Fillers placed between the rails maintain correct alignment. The assembly is fastened with heat treated bolts. This type of frog is used in yard and industrial tracks, where the traffic is light on both sides of the frog.
