      I am wondering about some info on transmitting sound by the tracks to speakers on the loco I found at this site: www.building-your-model-railroad.com/sound-effects.html

      It said:

      "Another type of analog system is to have a sound unit located at the control panel and use the track rails as "wires" to send the filtered audio impulse to a speaker on board the loco."

      "You could also use an FM broadcast from a unit on the control panel, use the rails as antennae to get the signal to the rails under the loco. The signal then jumps to the receiver and speaker mounted in the loco."

      Does anyone understand this and possibly have site on internet I could research more?

      Thank you,
      Diane
