Since overhead line failure usually has very considerable effects on train time-keeping, the concepts of reliability and availability are of extreme importance and justify the efforts which the S.N.C.F. has been making for 30 years to define an overhead line equipment maintenance policy and to adapt its organisation to the constantly developing operating conditions. But the diversity of its components, the increasingly aggressive nature of the atmosphere (in particular pollution), the external factors (varying temperature, wind, lightning, icing) and the action of the pantographs (uplift, oscillation, contact wire wear) make it especially vulnerable to the fatigue of certain components and a degree of ageing if prompt corrective measures are not taken.
