As the urban railroad durability period law has revised on march 19, 2009, the life cycle of urban railroad cars has lengthened to 40 years for the longest period. It seems to be attributed to the development of railroad car making technique along with their durability being longer thanks to the quality improvement of their materials and parts. As the stability of urban railroad cars is directly linked to the safety of passengers, safety should be considered first, and more precise examination is necessary for endurance extension. Hereupon, the rolling stocks with their durability near expiration should get precise diagnosis following the revised "RDG for urban railroad cars" This study aims to suggest a diagnosis method for the institute and the urban railroad operating body which enforce the revised diagnosis, through the case of Busan transportation corporation which firstly started the revised diagnosis after the durability related law has been revised.
