For any railway infrastructure manager, rail maintenance is a very important task to accomplish as rail maintenance is directly related to traffic safety as well as to availability and regularity. A big part of the signalling system (track circuits) are using the rails to transmit information. Consequently, it is essential that maintenance actions on the rail are carried out in an optimal way. The increase of rail traffic generates a decrease of the expected rail lifetime. The introduction of industrialized inspection and maintenance methods offer a possibility to increase the rail lifetime and thus to diminish the average cost of a track possession without reducing traffic safety. Based on very large infrastructure and rail maintenance databases, this study analyses whether it is beneficial to carry out preventive cyclic grinding and what cycles are the most adapted. This is done using a Weibull model for the rail lifetime distribution. Then, we model the impact of grinding on the lifetime distribution.
