Disclosed herein is a relay for a toy track set, the relay having: a first actuator; a second actuator; an object coupling the first actuator to the second actuator, the object being releasably received on the first actuator and the object has a mechanism configured to retract a cord into the object, the cord being secured to the second actuator at one end and the mechanism at the other end; a trigger moveably secured to the first actuator for movement between a first position and a second position wherein movement of the trigger from the first position towards the second position actuates the mechanism of the object and the object moves towards the second actuator as the mechanism of the object retracts the cord into the object; and a trigger moveably secured to the second actuator for movement between a first position and a second position wherein movement of the trigger from the first position towards the second position launches an object from the second actuator, wherein the trigger secured to the second actuator moves towards the second position when the object is drawn towards the second actuator by retraction of the cord into the object by the mechanism.
