Abstract
A grooved rail switch with a tongue rail device includes a tongue rail displaceably supported on a torsion-stiff support box for movement between a stock rail and a switch rail. The support box is made up of an upper slide plate, a lower bottom plate and flat bars extending between and welded to the slide plate and bottom plate. High strength bolts secure the stock rail to one side of the support box and the switch rail to the other side.
