“Right, that's it; no more Mr. Nice Engine. I am Master of the Railway!”

No More Mr. Nice Engine is the twenty-fifth episode of the seventeenth series.


One day, Diesel is shunting trucks full of dairy products for Hiro in the yard. To keep them from acting up, he is biffing them as hard as he can, spilling the milk churns. Edward tells Diesel to be gentle, but Diesel retorts that Edward should mind his own business. Soon, Hiro arrives and collects his train. Hiro, unlike Diesel, is nice to the trucks as a means of getting them to behave. He delivers his trucks to Knapford Station, but when the truck door is opened, the milk churns tip over and spill onto the Fat Controller's trousers, much to his dismay.

Hiro goes to the docks to pick up another shipment of cream. Diesel is there as well and still wants to convince him that the only way to make the trucks behave is with brute force. To attempt to prove this, he is coupled up to the back of Hiro's train instead of a brake van. Hiro sets off, not knowing Diesel's plan.

As the trucks biff and bash Hiro, he stays as patient as possible. Diesel gives them an extra hard shove to get them to biff Hiro harder; Hiro is still patient, much to Diesel's annoyance. When they reach Gordon's Hill, Diesel applies his brakes to help the trucks hold back. Hiro stays as gentle as possible until Diesel helps the trucks push him down the hill. Hiro is beginning to get angry at this point, and the trucks are now out of control.

The train speeds through Wellsworth, where Thomas is picking up passengers and sees what is going on. Hiro keeps trying to keep the trucks behaving nicely and remain calm himself, but Diesel keeps biffing and bashing Hiro and the trucks. At last, Hiro loses all of his patience and begins bumping the trucks as they reach Knapford, declaring "No more Mr. Nice Engine. I am Master of the Railway."

When the train finally reaches Knapford, Hiro applies his brakes as hard as he can in order to stop the trucks. Taken by surprise, Diesel hits the last truck so hard that three barrels of cream fly up into the air and splatter all over the Fat Controller, Edward and Hiro. The Fat Controller is very cross with Hiro for staining his trousers with milk for the second time in a day. Diesel tries to sneak away, but Thomas, who arrives on the same line, prevents him from escaping. Thomas asks Hiro why Diesel was at the back of his train.

Hiro is both surprised and angry that Diesel was the one biffing and bashing him throughout his journey. Edward then explains to Hiro and the Fat Controller that Diesel had spilt the milk from Hiro's earlier train, shortly before he had collected it from the yards. Everyone is extremely annoyed with Diesel, especially Hiro and the Fat Controller.

The Fat Controller decides to have Diesel learn the proper way to handle trucks as punishment, and decides that the best engine to teach him is Hiro.
