A swing bridge in the vicinity of Meppel, the Netherlands. There is absolutely no overhead line about the bridge; the prepare coasts by way of with raised pantograph. Sometimes gaps may be current in the overhead traces, when switching from one voltage to another or to deliver clearance for ships at moveable bridges, as a simpler choice for moveable overhead electric power rails.
Line tensioning in Germany Catenary wires are kept in mechanical stress because the pantograph triggers mechanical oscillations while in the wire.

The hole is necessary with the swing bridge to generally be opened and shut. To attach the conductor rails collectively if the bridge is closed, there is another conductor rail segment referred to as "rotary overlap" that is supplied having a motor. Once the bridge is completely closed, the motor from the rotary overlap is operated to turn it from the tilted posture into your horizontal posture, connecting the conductor rails for the changeover stop area as well as the bridge collectively to supply power.[ten]
