• Wheels of the railway vehicle play the important role for driving train through wheel-rail interaction. Especially wheel profile is one of the most important design factors to rule the running stability and safety of train. Accordingly maintenance of wheel like wheel profile control is also very important for securing safety and stability of train operation. This study presents the wheel wear measurement results of Saemaeul running on the conventional line. The train set included three different cars which have different shape of wheel profile including KNR profile currently used in Saemaeul. Train set was operated on Seoul-Pusan line with fixed train set formation for commercial service. Wheel wear measurements were performed periodically. We can find the influence of wheel profile on the wheel wear of the train running on the conventional line through the measurement results.
