- "Mama, Does the Railroad Track Go All the Way to Where the Sun Goes Down?" Book #4 continues to look at how these old early America structures played such an important part in molding railroad history at the turn-of-the-century. Using impersonated voices of depots and trains, and the silly humanlike cats, this book focuses on the lives and happenings in depots, trains and the building of railroads. Issues of safety with all its growth problems show the building of railroads was not always humorous but the depot/train occupants and families show the reader the beauty and depth of railroad growth in America.
