Glynn, a coffee pot engine, used to run the Ffarquhar branch line before Thomas came along. Once Thomas met him on his siding, Glynn was moved many times until he was forgotten. It was not until Thomas learned about Marion's 'talking Christmas Tree' that he found him again. The Fat Controller and the Earl both agreed to have Glynn put back in service.
One winter morning, the Earl decides to gives Glynn a tour of his estate, unaware that he leaves Stephen behind. Stephen tries to get the Earl to notice him, but the Earl is too busy discussing his plans with Glynn. Before he came along, Stephen had felt like a king, but now he had lost his crown. They tour many sights of the estate, including the Dinosaur Park and Ulfstead Mine, both times with the Earl paying no attention to Stephen.
Back at the castle, Glynn and Millie talk about the new Railway Museum the Earl is planning to open up. Stephen agrees, saying that Glynn should become an exhibit while Millie says that Stephen should be an exhibit himself, being the famous Rocket and all. Stephen brags about his place in the Rainhill Trials, but Glynn misinterprets this and points out it is the reason he is so famous. Outraged, Stephen challenges Glynn to a race to Knapford, the loser becoming an exhibit in the museum. Glynn is skeptical about this but agrees.
When the race begins, Stephen cuts in front, but with one line and the same speed, Glynn cannot overtake Stephen and Stephen cannot race ahead. When they reach Gordon's Hill, they find two separate lines but are still going slow. This annoys James and Gordon, who want them to get out of their way. Glynn and Stephen take no notice as they are actually too delved into a deep conversation about railways' part in history.
By now, everyone has heard about their race, and Stephen has recognized Glynn as his friend. Upon reaching Knapford, the Fat Controller berates them for racing on the mainline, delaying both Gordon and James. They both claim it is their fault when Thomas pulls up with the Earl, who claims he had a part in this. The Earl finds out the race was a tie and is happy that they will be working together at the castle. Despite agreeing with the Fat Controller about racing on the main line, he decides to have a yearly race elsewhere every year. Everyone cheers for Glynn and Stephen, who are now firm friends.
