Nice video, Terry. I tried to listen for the tick in the locomotives but I also could not hear it, although I believe my hearing is on about the same level as yours. I wear wireless headphones at night when watching TV. Digital audio, as what you get from a DVD or Blu-Ray movie, just is not processed very well any more by my ears. The headphones help a lot. As I said before, I'm looking forward to your next Christmas video with both trains.
