I noted today that MTH recommends that accessories in a DCS layout be run from a separate transformer to avoid making the DCS signal pass through coil windings or a circuit board. However, using the ZW as an example, the accessories are typically run from a separate TAP on the transformer than the track voltage, AND the DCS signal is injected downstream to the transformer anyway (in the TIU). So does the DCS signal backfeed through the TIU into the ZW?
