| Résumé | The major reasons for deterioration and premature replacement of rail on heavy haul track are reviewed with particular
regard to the mechanical and metallurgical factors influencing various damage mechanisms. Damage to the rail is
principally a result of wear; rolling contact fatigue; other types of fatigue defects; corrugation; plastic flow and head
crushing; martensitic layers, particularly from wheelburns; and batter of joints and welds. Some consideration is also given
to wheel damage processes. Conclusions are drawn regarding means of reducing rail (and wheel) damage on existing
systems. Future developments, primarily in the field of metallurgy, are also discussed. The proposed treatments address
both mechanical and metallurgical factors to contain the damage. Considerable substantiation is provided for the proposals
from an extensive review of published work. |
