I think FlyerChief can make a difference because of it's price level. Only time will tell us for sure.
Younger people can by a modern locomotive and pick up cheap Gilbert cars with older type track and have fun with their kids and grand kids. We just need to promote the hobby where we can and show them how much fun it can be through train shows where layouts are running.
Lionel's FlyerChief starting with the Polar Express was good for the S Gauge hobby.
