Amberg Rail IMS

Track surveying: faster, more efficient and more accurate

New measuring sensor: AMU 1030 (Amberg Measuring Unit)

  • Based on IMU technology (Inertial Measurement Unit)
  • Integrated microcomputer
  • Surveying of track alignment with AMU instead of a total station

Track surveying: faster, more efficient and more accurate. Amberg Technologies is expanding the well-established rail surveying system GRP System FX with the new Amberg IMS 1000 and Amberg IMS 3000 system configurations.

These configurations provide reliable and highly precise geometry information during the construction and maintenance of railway track systems – while achieving unparalleled productivity. IMS 1000 and IMS 3000 measure the inner and outer rail geometry of ballast tracks and slab tracks using a new, high-performance sensor – the Inertial Measurement Unit (IMU). Measuring 4000 metres of track per hour, the system’s performance is twice as high as of devices available on the market today. It furthermore ensures that the track will be measured reliably by providing a typical positional accuracy of ±1mm.

The IMS 1000 / IMS 3000 software processes the measurement data, analyses the quality of the track and reports the deviations to a design centreline. Correction data for tamping machines can also be generated directly. Advantage for the system’s users: the greater productivity and accuracy during track measurement reduces costs, enables efficient track maintenance and thus contributes significantly to the quality and safety of railway lines.
