Thanks to all grandpas for sharing your stories ...
The train hobby fosters a marvelous intergenerational exchange. Grandpas get an "infection" of youthful enthusiasm based on the "gee whiz" experience of grandkids and great grandkids. The youngsters benefit from the rub-off effect of practical wisdom from their grandpas who may advise, "The best junior engineers know it's best to drive the train safely and arrive on time; no reckless speeding."
