- "It's quite wrong that you silly old scrap engines should pull passenger coaches while I get freight cars!"
Diesel Causes Delay is a magazine story.
Diesel is cross that Thomas and Edward are taking passengers while he is shunting. This makes him careless, and one day Thomas finds the trucks are blocking the tracks between Thomas, Annie and Clarabel. Edward helps Thomas with getting the trucks out of the way, and Sir Topham Hatt is pleased with Thomas and Edward's hard work.
- In the third illustration, Thomas is seen pulling Annie and Clarabel when they are meant to be trapped by the trucks.
