This JVTC report identifies potential maintenance improvements and suggests maintenance actions which will support the reliability of the SSAB railway transport logistic system. The SSAB railway transport system needs an extra 23.5% wheel-sets waiting to be used in the maintenance process. Failure mode 331 represents 73 % of all maintained wheel axles. SSAB cost of re-wheeling (IS3) is 12.8 times higher than re-profiling (IS1). LKAB/MTAB cost for IS3 is 4-5 times higher than IS1 cost per wheel-set. An increase in IS1 and a decrease in IS3 lower the total maintenance cost. This result is in line with the full scale test performed by SSAB in 2011. More extensive studies on availability, reliability, maintainability, recoverability and maintenance supportability of the transport system should be carried out to find key performance indicators. The goal is to determine mean failure rate, decrease downtime and support maintenance.
