Abstract: A circuit arrangement for a model car racing track, having at least two tracks for model cars, wherein a positive busbar and a negative busbar are in each case assigned to each track, and a first driving speed controller is connected between a positive supply terminal and the positive busbar of the first track and a second driving speed controller is connected between a negative supply terminal and the negative busbar of the second track.

Abstract: The control of a plurality of toy vehicles (10, 12) using a plurality of operating devices (14, 15) is effected in such a manner that the speed of the toy vehicles (10, 12) is controlled by means of a tappet (26). Each operating device (14, 16) is uniquely assigned to a toy vehicle (10, 12). The operating devices (14, 16) are connected to a control center (18). The latter converts the positions of the actuating elements (26, 28) of each operating device (14, 16) into digitally coded signals and adds a digital address, which identifies a particular operating device (14, 16), to each digitally coded signal or data packet. The control center (18) sends the data packets via the bus bars of the motor racing track, as symbolized with arrows (30), with the result that said data packets are picked up in each toy vehicle (10, 12) using the current collectors 922) and are forwarded to the respective digital decoder (24).

Abstract: The invention relates to a track part (10) for a lane-guided toy car racing track, which, on at least one end face (18), has a fastening device for a further track part (10), wherein the fastening device has at least one first pocket (22) and at least one pin (20) that fits into the first pocket (22), which are arranged symmetrically to one another with respect to a center (24) of the end face (18), such that, when two track parts (10) are inserted together, one pin (20) engages in a first pocket (22) in each case. The fastening device additionally has at least one pair (28) of second pockets (30), which are arranged symmetrically with respect to the center (24) of the end face (18), such that, when two track parts (10) are inserted together, two second pockets (30) come into contact with each another in each case.
