Jon,
You must have much smarter kids in your neighborhood than I.
Does your son show interest in your trains?
We have a train show in Savannah in January every year.I noticed this past year that there were some trains set up for kids to play with.
And play they did. These were all 3 R layouts. Kids did not want to stop but when asked to allow another to play they would let the next
in and many went to the back of the line to go again. There were also some HO and N scale layouts set up. The kids would look at these
with the scale speed running trains and head for the O stuff. Unfortunately IMHO there is not enough model/toy train style activity in
this area for youngsters to get into.
I don't think model railroad in its many forms is dying but that it is thinning out a lot. I also think the Lionel LionChief control system is a
way to attract kids. They look at the controller and know what to do. And they will be able to expand their control systems much more
easily and quickly than I.
