Katie and Kenny, along with their father, are taken on a tour of the local railroad yard by an engineer with the railroad. The basis of the book is to introduce children to the role railroads play in our lives, their importance, and to stress safety around railroads and their equipment: "NO PLAYGROUND!" In today's world, the role of railroads has hardly been more important. Keith N. Corman feels it is a MUST to introduce to people why they are there, what they do, and, most importantly, how to be safety conscious around them.
