Sanding systems are used in rail vehicles to improve friction between wheel and track. Operation is either automatic or can be initiated by the driver, who can use it in a targeted way for starting-up and braking.
During emergency braking, sanding is automatically activated. The sand is contained in a sandbox and, when necessary, is conveyed by compressed air between the wheels and the track.
