First published in 1930, the text and illustrations are now in the public domain in the USA. ''The Little Engine That Could'' by Watty Piper is the classic children’s book about a small, cheerful engine that manages to pull a train full of toys and treats over a steep mountain after larger, selfish engines refuse to help. It teaches the timeless lessons of perseverance, kindness, and the power of a positive attitude. A train carrying toys, dolls, and good food for boys and girls breaks down on the wrong side of the mountain. Several passing engines are asked for help. A shiny new passenger train and a strong freight train both refuse because they are too "important," and a rusty old engine refuses because it is simply too tired. Finally, a small, cheerful Little Blue Engine is asked. Even though she is small and wasn't built to haul heavy loads, she agrees to try to help the stranded toys. As she struggles up the steep mountain, she chants the famous phrase, "I think I can, I think I can". Will her determination pay off? Will she be able to successfully pull the train over the mountain and bring joy to the children?
