To attach the conductor rails jointly once the bridge is closed, there is another conductor rail portion identified as "rotary overlap" that is supplied by using a motor. Once the bridge is completely closed, the motor from the rotary overlap is operated to turn it from the tilted posture in the horizontal situation, connecting the conductor rails with the transition finish section and the bridge alongside one another to produce electric power.[10]
