Right from the pioneering stage of railway construction, Switzerland's topographical conditions have determined the lay of the line. Even to this day, narrow radii decide the speed at which a line may be travelled and maximums of 80 to 100 kmph are the rule in some cases. For reasons of economy, semi-tensioned contact line systems were chosen when electrifying these lines and have stood the test of time to the present day.

Furrer+Frey stock a full range of components for the maintenance and renewal of these contact line systems.

Departures from the standard include tensioned simple contact lines with or without auxiliary line, the inclined catenary (an early Furrer+Frey patented design) or contact lines for rack-and-pinion railways with two contact wires.
