Percy's Post!, republished in 2012 as Percy the Post Train, is a magazine story.
One morning, Molly was feeling very pleased; she was given the post train to pull. Percy is upset, but the Fat Controller explains that she must learn how to do it in case Percy ever has to go to the Works. On the way to the Works, Percy passes Tom Tipper in his mail van. This makes Percy even more upset; he has to collect trucks in the countryside. Meanwhile, Tom Tipper was driving along some country lanes when the van's motor makes an odd noise before it breaks down completely. Then Percy rolls along and using a crane truck he has just collected, he is able to lift the broken van onto a flatbed. The Fat Controller is pleased - Percy has saved the post.
