We came upon this book at Border's shortly before they went out of business. It was a great deal, and who doesn't like trains, so we grabbed it without even leafing through it. Now that we've started reading it, I'm so glad we got it. The stories are simple enough for 2-3 year olds, but long enough for a bedtime story. The illustrations are the big selling point however, they are simply amazing, so full of details. I'm sure my son will be going back to the book by himself to contemplate and admire the pictures, even after it disappears from our reading list.
Actually, they're probably great early reader books as well. ( )
