This paper deals with the output characteristics of the rail wearing depth obtained by using reluctance rail sensor (RR sensor) for ordinary railway and Shinkansen (Japanese bullet train). The RR sensor consists of a U-shaped core (cut-core), two exciting coils, and two detecting coils, each wound with 250 turns of wire. The small-sized rail of 6kg rail is selected as the model, it is clarified that dependency of the output voltage of the RR sensor on the lift-off, the rail displacement, and the rail wearing depth. The rail wearing depth and the lift-off is measured by using two RR sensors.
