Thanks to its reliability it is still the most widely used method for removing contaminants and improving adhesion in that contact. Sanding devices were developed in cooperation with corporation, which deals with production of rail transport equipment, among other things. The most important part of sanding device is sand dispenser. Dispensers were experimentally developed at the test station in the cooperating corporation.
