There exists a hole amongst the overhead conductor rail on the changeover conclude segment and the overhead conductor rail that operates across the whole span of the swing bridge. The hole is necessary for the swing bridge for being opened and closed. To attach the conductor rails jointly in the event the bridge is closed, there is another conductor rail segment named "rotary overlap" that is provided which has a motor. When the bridge is fully closed, the motor from the rotary overlap is operated to turn it from a tilted place in the horizontal situation, connecting the conductor rails within the transition finish segment as well as the bridge collectively to provide electric power.[ten]
