This is some of the sketches for the steering mechanism of the ATN bogie. In the first design a hook-like mechanism on a rotating shaft is used and the hook-like structure keeps in contact with the side surface of the rail of the direction the bogie is switching to. The shaft is rotated by gears or actuators ( electrical, hydraulic or pneumatic). In the second design the bogie switches direction by using 2 guiding rails and a pair of guiding wheels. The guiding wheel is raised up to keep in contact with the rail according to the direction the bogie switches to. The steel control arm is either raised up or lowered by actuators. The bogie also has an extra guiding wheel to keep the bogie in contact with rail. The third design shares similar design. In both the second and third design plastic guiding wheels are used in order to absorb vibration during direction switching action and provide better gripping force on the guiding rail
