The main objective of the study is to provide the criteria for determining the proper life cycle of rebuiled diesel-electric locomotive currently being operated in KNR. We predicted the most critical sections of the underframes and tested the diesel-electric locomotive vehicle to measure dynamic stresses applied to the underframes. The fileld test of the diesel-electric locomotive estimated 17.08years based on the fatigue-life estimation when they are continuously used in the present operation condition.

The main objective of the study is to provide the criteria for determining the proper life cycle of rebuiled diesel-electric locomotive currently being operated in KNR. We predicted the most critical sections of the cast-iron bogie and tested the diesel-electric locomotive vehicle to measure dynamic stresses applied to the bogie. The fileld test of the diesel-electric locomotive estimated 9.90years based on the fatigue-life estimation when they are continuously used in the present operation condition.
