Abstract
A railroad grade crossing assembly for blocking vehicle access across a railroad crossing including a gate assembly connectable to a stanchion and light assembly. This gate assembly is movable between a generally upright position to permit vehicle access across a railroad crossing and a generally horizontal position for blocking vehicle access across the railroad crossing. The gate assembly further includes a telescopic arm assembly for completely closing vehicle access to the railroad crossing. In another embodiment of the invention, the railroad grade crossing assembly includes a gate movable between a generally horizontal retracted position to permit vehicle access across a railroad crossing and a generally extended horizontal position for blocking vehicle access across a railroad crossing, the gate includes a telescopic arm for completely closing the railroad crossing, a first and second stanchions. The railroad grade crossing assembly also includes a battery to power the gate and a solar panel to recharge the battery. A low battery indicator may also be includes to indicate that said battery has a low voltage. A listening device is provided to detect the sound of an oncoming train and activate the gate, and a sensor is provided to sense when a train has passed and thereby cause the gate to retract.
