Abstract: This invention concerns a positioning device for a transport vehicle, constrained to travel along a track. These transport vehicles are propelled by linear motor propulsion. Along the track are positioning points typically located at stations for entering and exiting the vehicle. Associated with the means for linear motor propulsion, stationary in the track at the positioning points are two switches, means to detect the velocity of the vehicle and a logic control circuit, so that acceleration, deceleration and zero strength excitation signals can be applied to the linear motor in the vehicle so as to cause the vehicle to come to rest at the positioning point. The apparatus controls a vehicle travelling in either direction along the track.
