Major projects with the rail milling train MG31

Linmag works with the most powerful rail milling machine available on the world market. The MG31 is equipped with six milling units (three per rail), which allow flexible material removal between 0.3 mm and 4.0 mm in just one pass. Following the milling units, one circumferential grinding unit per rail is integrated, which serves exclusively for polishing and smoothing the rail surface.

For complete quality control of the work carried out, the milling train is equipped with an integrated on-board measuring technology to determine and document the transverse and longitudinal profile as well as crack conditions (detection of cracks and information on their depth).

The high material removals and the fast feedrate make rail service by the MG31 to a unique method. After enrollment, the machine can be operated by the customer as an in-house solution or as a turnkey solution.

in rail re-profiling is guaranteed with LINMAG MG31 rail milling train comprising 6 milling units. We are able to remove rail defects of up to 4.0 mm depth in only one pass, this is unique. We also employ this rail milling equipment on our high speed rail lines as we rely on very high precision in this case. The LINMAG Service Team provides a reliable equipment and is available 24/7. They will immediately respond with the appropriate action to avoid any down time, I appreciate this most of all.”
