Liquid lubricants and friction modifiers are designed to reduce noise and wear of railway material in track curves. Since there are several causes of noise, there are alternative methods of applying the products. The two basic methods include application using a stationary lubricator on the rail and, above all, spraying onto the rail/rail skirt from a nozzle located on the vehicle.

The basis of the solution is the analysis of the problem on site and the performance of tests. Our proposal is based on the optimization of existing systems and installations.
