Regional railways, where equipment is aging, frequently experience derailment accidents due to gauge widening. This paper shows a detection method of gauge widening by measuring the positional relationship between the rails and the wheels. The proposed method uses a small, simple camera, which is easy to install and allows inexpensive measurements. The points where the gauge is widened, are identified by section images of rail and wheel extracted from moving image shot by the camera. An overview of the measurement device and experimental results of a commercial train are reported.
