Understanding high coupler forces at metro vehicles
Vehicle System Dynamics, 2007Couplers of motor units connect the wagons mechanically, electrically and pneumatically. Nowadays they are also designed to meet crash requirements. Since the traction and braking forces are distributed along the motor unit, coupler forces occuring during operation are considered to be low. In most cases, this is actually true.
