English: The collector of the Filovia system consisted of "a four wheel truck, placed on top of a boom, which is kept in contact with, and runs under the trolley wires in the same way as the ordinary tramway trolley wheel. Its design and construction have been so perfected that it will allow a displacement of the car to the extent of about 12 ft. from either side of the trolley wires, so that it will take easily very sharp curves, and will not leave the trolley wires even when running at a speed of 18mph.
