KURZFASSUNG DE 2735521 A A model railway track carries several, remote-controlled engines. A constant l.v. is supplied to the track via a transformer. Each railway engine is operated by the same voltage. A multi-channel radio transmitter produces control signals with which one or several trains can be operated. Each motor is governed by an individual regulator which responds to one particular channel of the transmitter. Additional equipment, such as train whistle or lights, can be operated in the same manner.
