No Joke for D199

No Joke for D199 is the fifth episode of the first series.

Plot
D199 is proud of his smart light blue paint, and his driver tells him that he brightens up everyone's day. Shortly afterwards, D199 boasts to Diesel and Dennis that he is the smartest and most useful diesel on the line. Diesel and Dennis disagree. Later, as D199 boasts to Diesel 10 that he is the pride of the line, Diesel 10 tells him that he is only a goods engine. D199 lies to Diesel 10 that the Fat Controller has plans for him, and Gordon believes him, much to D199's concern.

Diesel is shunting coaches in the yard. Diesel tells D199 that they are for Diesel 10's express, and that he will fetch D199's trucks next, but D199 decides to trick Diesel, lying that the Fat Controller told him that he is to take the express, and that Diesel 10 is to pull the trucks. He is then coupled to the coaches and steams out of the yard just as Diesel arrives with D199's tanker wagons for Diesel 10, leaving him and his driver shocked and furious.

Meanwhile D199 is enjoying himself enormously, thinking to himself how clever he is. His fun doesn't last however; he finds the Fat Controller waiting for him at Elsbridge and he quickly reprimands D199 for his naughty actions, and sends him to his shed. D199 ends up with Diesel 10 and Class 40 teasing him by asking each other who will pull the express. The next day, D199 is let out of the shed and apologises to Diesel, who gives him his trucks. D199 then shunts trucks in the harbour for the rest of the day.

As D199 and his driver prepare to head home, a man arrives and tells D199's driver that he is to attend an important meeting with the Fat Controller which he must not be late for, and he asks for a ride in D199's cab. D199' driver recognises the man as a railway inspector and agrees. When D199 arrives at Knapford, the inspector praises D199. The Fat Controller agrees and tells D199 that he has once again proven himself to be a Really Useful Diesel.
