  More than half of steel railway rivetted girders have been in service over 60 years, and most of them are required to be used moreover. In order to meet such a demand, it is needed to examine fatigue limit state of rivetted railway girders. In this study, fatigue tests were carried out using actual rivetted girders, in which unique characteristics of railway structures were considered such as corrosion condition of girders and field welding of gusset as well as cover plate. Consequently, valuable information useful for structural inspection and maintenance has been obtained.
