Electrical Engineering in Japan, 2003 AbstractThe acceleration and deceleration rate of a train depends on the tractive force. When the wheels of a train slip on the rails, the torque is decreased to avoid continuous slipping. This is done because the tractive coefficient between the wheels and the rails has a peak at a certain slip velocity.
