Operating Principle
Power Collector
When the bogie pantograph is retracted in rest position:
…the power collector in the upper position is unable to activate
the power line segments; the pulling force is not enough to lift
up the belt
The vehicle can run over the line in coasting without activating
the segments
All the segments are not energized and connected to ground

Operating Principle
When the bogie pantograph is released:
…the power collector is in contact with the segments and its
magnetic force attracts the flexible ferromagnetic belt, that push
up the internal movable conductive contacts, allowing the
closing of the electric circuit and the power transmission from
the segments, in contact with the collector, to the vehicle
