Measurement of track position errors

In rail transport, the new construction and reconstruction of track sections is subject to ever increasing requirements. A faultless track geometry is essential, especially for high-speed lines. In order to ensure this, tamping machines are used, which compact the ballast lying under the sleepers to give the track the necessary grip and avoid positional errors. To evaluate the exact position of the track, precise information about the condition and position of the track in front of the track tamping machine is required. Two INC5701 inclination sensors from Micro-Epsilon record the transverse and longitudinal inclination in a mobile measuring device and transmit this information to the tamping machine driving behind it. This means that the compaction of the ballast is precisely adapted to the track position.
