A rail barricade includes a bottom rail and a U-shaped body frame having a top rail and a pair of vertical rails. A plurality of vertical spokes are located between the vertical rails. The bottom rail further includes an opposing pair of curved ends each having a projection that is received in a notch in one of the vertical rails. The connection is then welded. A foot is pivotally attached to each of the vertical rails. Hooks are attached to one of the vertical rails for attachment of a second rail barricade.
