Modern treatment.

In 2008, PORR put the first rail milling train in Austria into operation: the Rail milling train SF03W-FFS. It was an interesting alternative to the previously used technology – rail grinding – which used to be the only option for reprofiling worn out rails.

The rail milling train (which looks like a locomotive) can quickly remove the defective material near the rail surface and running edge in a single run.

And the rail’s useful life is considerably extended through exact rail treatment, with continuous removal of rail defects and precise restoration of the rail profile. The rail treatment does not require cooling or cleaning media. Vacuuming and conveyor systems move the swarf from the treatment point and from the machine into the swarf hoppers inside and outside the rail milling train. Another advantage over conventional rail grinding technology is the avoidance of flying sparks and dust emissions.
