In order to enable the use of highly resistant materials difficult to weld or not weldable at all for a stock rail (2), the tongue box for grooved rail switches, which includes a stock rail (2), a slide plate (5) and a side rail (3), whereby the side rail (3) and the slide plate (5) and a base plate (4) are welded together forming a box-shaped section with the stock rail (2), is designed in a manner that the stock rail (2) is connected with the box-shaped profile in a positive and force-transmitting manner by clamping pieces that are welded with the box-shaped section and/or the base plate (4). |
