Abrégé

A system outputs a signal indicative of a distance travelled from a datum, by a model train over a train track with an electric conductor. The conductor is arranged in a square wave form below the train track and has an electric current flowing in it. A model train is fitted with a transducer that detects a variation in a magnetic field strength (H) arising from the electric current in the electric conductor and derives an instantaneous magnetic field strength (H) which is proportional to a distance between the transducer and a maximum magnetic field strength (H) occurring where the electric conductor crosses the train track. Zones are defined between two adjacent crossovers of the electric conductor and a counter counts zones which correspond to the number of zones through which the model train has travelled. When this distance is added to a distance, corresponding to a proportion of a zone through which the model train has travelled, the total distance measured from the datum is derived.
