Slippery rail
Slippery rail, or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead causes trains to experience less adhesion (grip). This can lead to wheelslip when the train is taking power, and wheelslide when the train is braking. The most common cause of contamination is fallen moist leaves that lie on and cling to the top surface of the rails of railway tracks. The condition results in significant reduction in friction between train wheels and rails, and in extreme cases can render the track temporarily unusable. In Britain, the situation is colloquially referred to as "leaves on the line".
