To form a railroad control gate of a simpler configuration such that it enables operation that can be dealt with by one personnel.

The railroad control gate is for adjusting a railroad grid relative to an on-rail edge on a support layer supporting the railroad control gate, and for performing subsequent placing concrete. In an embodiment in which a cross rail 16 supporting a rail gripper 17 and capable of horizontal adjustments is hung via an adjustable hanging fitting from an upper support cross girder 5 which can be matched in height to a support leg in some cases, the cross rail 16 is height-adjustably hung on spindle carriers 10 and 11 placed in longitudinally different positions and being vertically slidable toward the upper support girder 5.
