A pantograph is "a jointed mechanical device in the shape of a
parallelogram. . ." when viewed from the side.
More modern ones (such as on the new Amtrak Acela power cars) only
have one side of the parallelogram. In the case we're discussing, it
has a bar on the top acting as the current collection device. The
bar is perpendicular to the wire containing the current and nearly as
long as the car/locomotive is wide.
