The Rail Cleaner DR40 is used after rail replacement to ensure the rail is rust-free. The cleaning machine brushes the top of the rail head, removing oxidation and ensuring a good friction contact between the wheels and the rail surface. In doing so, it guarantees an effective electrical connection on the top of the rail for efficient functioning of the track circuit (the signal system).
Two people are needed to place the Rail Cleaner DR40 on the track, but it can be operated safely and accurately by just one. The operator stands with one leg on either side of the rail and pushes the machine, which is guided on the rail by rollers. A thermic engine drives a metallic brush in rotation.
