Upon the results of the trial operation, NÖVOG ordered components for the "TOR" spraying of HeadLub®90 friction modifier (Igralub AG) for the top of the rail head for other three low-floor, three-section trams operated on the Mariazellerbahn. All four spraying systems will be controlled automatically upon receiving signals from the vehicles' GPS. The friction modifier is the same as the one used in the popular “lubricating tram” operating in Prague.
