I thought you might be interested in this. I happened to hear about a wireless DCC system being developed while listening to the Model Railcast Podcast. Here is the link:
It is a neat and really simple idea. Basically a transmitter sends out the DCC signal over the air instead of the rails and that is picked up by a receiver in the locomotive. There is a video showing this function with a battery operated train, which is suggested right now. But it isn't hard to see that this could be adapted to use power from the rails and DCC signal over the air. It seems like this would overcome some of the objections to DCC, two of which come to mind:
- No expensive track boosters would be required. Just put the power on the track and no need to have the expensive booster to pass through the DCC signal.
- No issue with momentary interruptions on the track.
I don't have any command control yet. I have been waiting on the sidelines because it seems changes are coming fast and I really like the iPod/iPad interface that is available with DCC for $10. I also like On30 as well as the three rail and it would be nice to have one controller for both. I am hoping O gauge makes it there.
