A woman looks at a Z scale railroad model.   There is something that draws us to trains no matter our age. As a kid, I remember my parents taking  my two sisters and I on a train from Casa Grande, Arizona  to St. Elmo, Illinois to visit my grandparents. One of dad's funniest memories from our train trips was when my youngest sister woke him up one night on the trip with the question, "Who's driving this thing?". I love the sound of trains. My grandparents lived two blocks from the tracks in their small town. When I laid in bed at night right next to the wide-open window I felt comfort from the sound of the train whistle and the rhythmic clunkety-clunk  of the wheels on the tracks
