Abstract:
A method for creating a plurality of redundant transponder responses within a reply in a transponder device (11) on a model railroad layout (4) comprising the steps of: providing said transponder device (11) communicating with said model railroad layout (4), providing transponder current generating means (70) for creating said plurality of redundant transponder responses with controlled magnitude and durations, providing a transponder timing generator means (71) that controls said transponder current generating means in response to predefined time periods that said transponder timing generator means decodes from a track voltage encoding method, and arranging said redundant transponder responses to function with a transponder detector including a multiplex selector (74) to multiplex current sensors (5), wherein each said current sensor is connected to a separate track section for detecting the transponder device on an occupied track section.
