Described is a use of at least one fiber-optic sensor unit for measuring a mechanical variable which affects a rail having a certain length and a neutral fiber that extends along said length of the rail. The at least one fiber-optic sensor unit is disposed at an angle of 30° to 60°, in particular 45°, relative to the neutral fiber or at an angle of -30° to -60°, in particular -45°, relative to the neutral fiber. The at least one fiber-optic sensor unit is irradiated with primary light in order to generate a signaling light in a reflection mode or transmission mode. The intensity of the signaling light is sensed. The signaling light is evaluated.
