Catenary

In Europe, the organizer was the hostess and her principle was catenary.

The structure of the model chosen was catenary, and only one nonlinearity was introduced, in that part of the model representing bone growth.

The sequence of soils of a more or less catenary nature as seen on the Martin Estate is about as follows :

The result was catenary being torn down several hundred feet at a time.

The colour-lights showed up much better than the semaphores which, in spite of their approach warning boards, are not readily visible at any distance between the supports for the catenaries.

The electric overhead was catenary, using 0000 contact wire, and the new railway employed the latest in electric block signal systems.

In addition the catenary itself is divided into 1-2 km sections (corresponding to mechanical sections or tension lengths) with motorized remotely controlled sectioning off-load isolators such that only one train is likely to be immobilized at any one time as a result of an incident associated with the catenary system.

Overhead construction was catenary rather than a single wire to allow the use of pantographs instead of trolley poles so that speeds could be higher.
