The Little Engine That Could

''The Little Engine That Could'' is a 1930 American folktale by Arnold "Watty Piper" Munk, existing in the form of several illustrated children's books and films, best-known for its signature motif: "I think I can!"

The story originated and evolved in the early 20th century, but became widely known in the United States after publication by Platt & Munk. The story is used to teach children the value of optimism and hard work. Based on a 2007 online poll, the National Education Association listed the book as one of its "Teachers' Top 100 Books for Children".

The original book version from 1930 will enter the American public domain on January 1, 2026. Provided by Wikipedia
