Duck (later re-titled No Nonsense, Duck!) is the twenty-first book in the My Thomas Story Library series.
Percy is pleased when a new engine called Duck comes to help in the yard, but the bigger engines order the two engines about. The Fat Controller soon puts a stop to that and later sends Duck to work on his own branch line.
- This book is based on the stories, "Duck Takes Charge" and "Donald's Duck" from the Railway Series books Percy the Small Engine and Oliver the Western Engine.
- The Small Railway, which, (at the time of publishing,) was only featured in The Railway Series at the time, is mentioned.
- This once came free with a Thomas Magazine.
- In the last illustration, Donald does not have a tender as a coach is coupled behind his cab bunker.
