A railroad grade crossing assembly for blocking vehicle access across a railroad crossing including a gate assembly (10) connectable to a stanchion and light assembly (12). The gate assembly is movable between a generally upright position to permit vehicle access across the railroad crossing and a generally horizontal position for blocking vehicle access across the railroa d crossing. The gate assembly further includes a telescopic arm assembly (16) for completely closing vehicle access to the railroad crossing. The railroad grade crossing assembly also includes a battery (150a) to power the gate and a solar panel (152) to recharge the battery. A listening device (158) is provided to detect the sound of an oncoming train and activate the gate, and a sensor (160) is provided to sense when a train has passed and thereby cause the gate to retract. |
