And in the 1950's people were probably saying how the everything had to be electric and kids didn't want wooden toys anymore. Just a funny observation. Technology certainly changes things, and they have certainly made our trains better, or at least more interesting.
An interesting note to all this, Lego's continue to sale. My son spends more time with is Lego's building his own creations. The problem with the trains I see with kids is they re more complicated to deal with for them than other things. If there was a way around this, I think more would be involved at younger ages.
There is a lesson to be learned from Thomas Wooden Train sets that are still extremely popular. They are expensive to buy, but basic enough for kids to make their own world with and have fun. Kids still do like hands on experiences. They like to build things and make the move.
