The speed of a driverless vehicle is controlled along the length of the module from an incoming high speed to an outgoing low speed or vice versa. The module includes first, second and third aligned drive tubes between tracks adapted to support a vehicle. A first motor is coupled to the first drive tube for driving the same at a first high speed. A second drive motor is coupled to the third drive tube for driving the same at a second low speed. Clutch means are provided for enabling only the first motor to drive said first and second tubes and then enable only the second motor to drive the second and third tubes.
