Rail wheel wear and lubrication strategies are reviewed in this paper. A rail lubrication benchmarking model is proposed to compare different infrastructure players and different rail sections. In doing this each body and section in the system must be defined in the same way. The different bodies must use, or be able to translate and convert, to a common maintenance terminology. If not, the comparison will not be able to direct towards right decisions. In order to identify and compare necessary maintenance performance indicators, benchmarking parameters, for rail lubrication, and analysis of the lubrication performance on a specific line section, we suggest a maintenance management system to monitor rail wear as function of curve radii and time. Factors such as seasonal ambient temperature variation; change of lubricant, any significant changes in traffic movements, e.g. uni-directional changed to bi-directional, change in type of traffic and change in maintenance execution shall be accompanied by a continual review of lubricator status. There exists a link-and-effect coupling between inspected rail wear and lubricator efficiency. However, several critical engineering areas must be taken into account to establish an operating point in order to cover the whole spectrum of the performance of lubricators. By plotting the operating point in a diagram it is possible to benchmark different rail sections with itself. Aggregated data can then be used for benchmark between different track sections.
