I like trains and cars, and I also have experienced Bruce's work (Classic Cars, Cars of the Fifties, American Muscle Cars) so whe I saw that he authored this work, I knew that I would enjoy it.
The pictures are detailed -- especially the steam engines. Bruce took time to get the valve work and driving rods right. There was an ocassional gaffe, but those were easy to overlook when considered in the total context of an excellent work.
If you are an adult, if you like trains, and if you like to color, this is a book for you.
