To connect the conductor rails collectively if the bridge is shut, there is yet another conductor rail portion termed "rotary overlap" that is provided using a motor. In the event the bridge is completely shut, the motor from the rotary overlap is operated to show it from a tilted placement into your horizontal place, connecting the conductor rails within the transition conclusion section along with the bridge together to provide ability.[10]
