One of my favorite ever since I bought a shiny new copy at the school fair in the 1960s. Choo-Choo, somewhat like Sparky in another sweet children's book, is sad because he's become old and no longer useful. The happy ending for Choo-Choo as well as Sparky in that similar book is that they find a way to become needed once more. Very appealing color illustrations accompany this dear story. Idk how this book has such a low rating when it is so beloved by me!
