Designed for surface trains, subways, trams, and railway vehicles in general. It takes the form of a sequence of modular stations dedicated to cleaning specific areas:
- For the sides, the imperials (diesel trains) or imperial fittings (tiles) with brushes;
- For the front and the rear also with inclined fronts or complex shapes with brushes.
The sequence of arches for spraying chemicals, wetting, or drying completes the washing unit.
