Electronic measuring devices for the inspection of longitudinal profiles

The geometrically perfect production of welded rail joints and the correct alignment of the rails are essential parameters for the durability of the welded joints. This has been proven by trials and model calculations. It is therefore necessary to document these factors – namely using measuring technology that is both objective and reliable alike. Thus, you will also be in an excellent position with respect to the construction of new high-speed rail tracks, heavier track loads and demands for better ride comfort.

Straightness measurements of the running surface and gauge face longitudinal profile before and after grinding works are performed with our RAILSTRAIGHTs. After measuring on-site, the measurement data are transmitted via Bluetooth to and displayed and documented on the measuring computer or using the GOLDSCHMIDT DIGITAL APP. The measurement data is uploaded directly to our database solution DARI® so the data can be analyzed and accessed globally.


  • Simultaneous measurement of running surface and gauge face
  • Complete electronic documentation of straightness measurement after welding and, therefore, logging of acceptance results
  • Helps to ensure precise track position
  • Reduces the rail and wheel wear and consequantly decrease maintenance costs
