STRAY CURRENTS: CORROSION AND MEANS OF PROTECTION

COURANTS VAGABONDS: CORROSION ET MOYENS DE PROTECTION

After pointing out the originality of return circuits for electric traction currents, the article reviews the various types of corrosion encountered in a railway environment. The process of electrolytic corrosion by stray currents which has been observed only along de-electrified tracks is described. The various passive and active methods to protect rails and pipes from corrosion are recalled, in particular the system of cathodic protection by electric polarized drainage, generalized by the SNCF. Some examples of cathodic protection installations are given.
