The invention relates to a form for producing concrete rails for rubber-tired vehicles which are guided on a track. In contrast to steel rails, concrete rails no longer bend after production, so that numerous different molds are required for curves, transition curves, super elevations, and the like. This drawback is avoided with the form according to the invention, wherein the form makes it possible to produce both straight rail sections, as well as rail sections having varying curvatures, using the same mold. As a result, the expenditure for rail forms is considerably reduced.

DETAILED DESCRIPTION What I claim is: 1.
A form for producing concrete rails having a horizontal tread and a vertical guide portion for track-guided, rubber-tired vehicles, said form comprising: a frame which is provided with a first side; at least one first support and at least one second support, with said second support being adjustably connected to said first side of said frame; a sheathing having a first end and a second end; a first lateral sheathing having a first end which is connected to said second end of said sheathing; a second lateral sheathing having a first end which is connected to a second end of plate members; a guide portion sheathing which is provided with a first end and a second end, with said second end being positioned at substantially right angles to said first end of said first lateral sheathing and being connected to said first support, and with said guide portion sheathing being continuous and extending along the entire length of said form, and with said guide portion sheathing being capable of being adjustably curved by shifting of said first and said second supports; and a tread sheathing which is provided with said plate members and a resilient covering, with said plate members being separated from one another by a gap and with said plate members being arranged adjacent one another following the longitudinal direction of said form, and with said plate members being provided with a side remote from said first support, wherein said last-mentioned sides of said plate members are connected by said covering which thereby bridges said gaps and forms a flat shuttering surface, and with a first end of one of said plate members being connected to said first end of said guide portion sheathing forming substantially at right angle therewith.
2.
A form according to claim 1, wherein said first and said second supports are arranged in a row and are positioned at right angles to said guide portion sheathing.
3.
A form according to claim 1, wherein said plate members are provided with strengthening supports
