A method to determine the position of a locomotive (100) by having a first device (306) measuring the electromotive force from a propelling motor (105) and calculating the speed; combined with detection of fixed reference points by measuring of the magnetic field generated by permanent magnets (106) at known positions. At regular intervals this information is passed to a second device (108). By use of a pattern recognition algorithm the second device estimates the position and operates the locomotive according to location-based behavior. The first device characterized by having a magnetic field sensor (302) integrated on an ordinary model railroad decoder, which already supports motor measurement and packet transmission. The second device characterized by having a data packet receiver (403) and an Ethernet interface (405) for communication with a command station (109). A microcontroller (402) utilizes a parameterized representation of the model railroad layout to determine the position of the locomotive. From the position proper behavior is determined and corresponding speed commands are sent to the command station. Other methods and embodiments are described and shown.
