1. A safety crossing gate for a railway crossing comprising:
- a secondary gate rotatably mountable to a primary crossing gate, wherein said secondary gate is a rigid elongated member having first and second opposite ends, wherein said second end of said secondary gate is rotatably mountable to a free end of said primary crossing gate by a rotatable coupling mountable to said second end of secondary gate and said free end of said primary crossing gate so as to allow selectively actuable rotation of said first end of said secondary gate relative to said primary crossing gate in a generally vertical plane containing said primary crossing gate when said secondary gate is rotatably mounted to said primary crossing gate by said rotatable coupling, a selectively operable actuator mountable to said secondary gate and said primary gate for selectively actuable rotation of said secondary gate relative to, and only above, said primary crossing gate about said rotatable coupling when said secondary gate is mounted to said primary crossing gate and said primary crossing gate is rotatably mounted to a gate actuating mechanism housing, said secondary gate rotatable only above said primary crossing gate in said vertical plane between an extended position extending from and generally parallel to said primary crossing gate and retracted position rotated upwardly at least substantially 90 degrees from said extended position, said secondary gate rotatable only above said primary crossing gate so as to allow delayed actuation of said secondary gate after deployment of said primary crossing gate into a horizontal position blocking a first lane of a roadway entering said railway crossing, wherein said delayed actuation allows vehicles to escape from said railway crossing after said deployment of said primary crossing but before said delayed actuation of said secondary gate into said extended position, said extended position blocking a second lane of said roadway adjacent said first lane.

Abstract
The safety crossing gate for a railway crossing of the present invention includes a secondary gate rotatably mounted or mountable to a primary crossing gate. The secondary gate is a rigid elongated member having first and second opposite ends. The second end of the secondary gate is rotatably mounted or mountable to a free end of the primary crossing gate by a rotatable coupling mounted or mountable to the second end of secondary gate and the free end of the primary crossing gate so as to allow selectively actuable rotation of the first end of the secondary gate relative to the primary crossing gate in a generally vertical plane containing the primary crossing gate when the secondary gate is rotatably mounted to the primary crossing gate by the rotatable coupling.
