Electric trains require high deceleration capability and stable traveling performance. This paper focuses on electric train deceleration under wet railway track conditions. Electric trains typically have electric brakes and air brakes. Under low-adhesion-coefficient conditions, each axle experiences skidding. The driving wheel may then become locked because of the air brake. This causes damage to the wheel tread that can result in what is called a “wheel flat”. Many studies have focused on overcoming this problem. This paper proposes an anti-lock control system for electric train driving wheels using driving wheel speed and acceleration. This anti-lock driving wheel control system is evaluated in this study using numerical simulation.
