Hi Hugh,
A catenary (not sure of the correct spelling) is a wire or rope
suspended above. In rail traction terms this would mean a wire hanging
above and along the legnth of the rail-track, from which the power is
drawn to drive the train. The old trams were driven by electric motors
supplied by a catenary wire over the tram track.
