Track state determination method for determining values representative of railway track condition, especially the rail profile using a light intersection method, whereby a light inspection beam is incident close to the wheel

摘要

Method for determining a first condition value, especially the profile of a rail (1) using a light intersection method, whereby a first light projection (4) is aimed near the wheel support point of a first wheel (10) with the light projected at an acute angle to the rail surface. An Independent claim is made for a device for determining a first condition value, especially the profile of a rail (1) using a light intersection method
