Abstract: A switching arrangement for model trains includes tracks arranged in multiple closed paths which have at least one track section in common. The various paths are interconnected by remote controlled track switches. In order to assure that the train traverses the tracks in a random fashion, a signaling device activated by the passage of the train, is located in the common track section. The speed of the train, and hence its residence time over the signaling device, determines the length of the signal produced by this device. This signal drives a motor for its duration, which motor moves a selection arm that passes contacts wired to the tracks switches. The location of the track switching contacts are randomly spaced over the path of the selection arm. Since the train may move at various speeds and the contacts are randomly spaced, the positions of the track switches that are operated by each passage of the train over the common section of track are randomly selected.
