Track Degradation


Track degradation negatively influences the health condition of the railway infrastructure, increases the noise level that affects people living in the surroundings and in a worst case it can make a huge impact on safety as severe defects/failures can result on derailment. Track degradation involves complex interactions between environment, vehicles, wheels and track interface, structure. It can be reduced with the proper preventive maintenance, or when in a very late stage via corrective maintenance operations (replacement). Thus, for track maintenance to be effective, the planning should consider not only costs but also the dynamics of degradation of the railway assets.
