• Corrugations with comparatively long wavelengths of about 30 cm were recently found on some high rails in sharply curved tunnels. In this particular line, these corrugations were only found in tunnels, not found in any open sections with sharp curves. For the above reason, these corrugations seem to be generated by the effects of tunnels as well as the lateral forces observed in sharply curved tracks. Hence, we measured the track vibrations before and after the rail replacement in two sharply curved tracks with a same radius; one is in a tunnel and the other is in an open section. As a result, these track vibrations showed different properties, which suggested the generation mechanism of the corrugations.
