Freight Train is a 24 page children's picture book written and illustrated by Donald Crews. It lacks any story, but rather describes the inner workings of a large cargo train. It was named one of 1979's Caldecott Honor books.
The popularity of this book has led it to be completely remade in 2001 by Crews. The new edition, titled Inside Freight Train, features fold-out panels, revealing the insides of the various train carriages.
