Query: Very good reference book for the Lionel train enthusiast.

This book is a must have for both the serious collector and casual Lionel train fan alike. The book gives good background information for each segment of Lionel train (locomotives, flat cars, etc.) as well as insightful commentary on each train car model. The pictures are excellent but if you are looking for detailed information on the parts and assembly of the trains then this book will not help.That said, the book is highly recommended for the Lionel fan who wants to see the full lineup of Lionel trains produced (post-war) and their approximate values.
