ATMO rail grinding in test

The testing with the new ATMO rail grinding trailer (Automatic Track Machine Oscillator) for urban tramway networks is giving exciting results so far. Within the scope of In2Track3, Plasser & Theurer in collaboration with Wiener Linien, are working on analysing and improving the performance of the machine.

It combines the sliding and oscillating grinding methods, both being tested and compared at speeds up to 30 km/h. Equipped with 8 grinding stones, the ATMO provides a smooth rail head and also clean the rails of leaf litter. The result of rail grinding not only reduces noise levels but also actively prevents accidents by averting operational dangers.
