Thomas and Edward's branch lines are very important to the railway. But their tracks and bridges are not as strong as those on the main line, so the Fat Controller does not allow the larger engines to run on them. Although this is purely for safety, Gordon believes the rule is for another reason entirely.
One day, he complains to Edward about BoCo being allowed to take main line trains when he is only supposed to work on the branch line. Edward jokingly suggests that Gordon ask if he can take BoCo's trucks in return, but Gordon refuses to consider the idea. Edward notes that it might be a nice change of pace, but Gordon claims the Fat Controller would never agree and states that branch lines are vulgar before snorting off, followed by an amused Edward.
Every evening, both Gordon and Edward take late-night trains. Gordon takes the express along the main line, while Edward leaves a few minutes later with a branch line train. Normally everything runs fine, but that evening there is trouble when a lady with a large green floppy hat says goodbye to a friend on the platform. When it is nearly time for Gordon to start, his fireman looks back and, seeing something large and green waving, assumes the guard is waving the flag. As a result, Gordon leaves with the majority of the passengers, the luggage, and the guard stranded on the platform. Everyone is surprised and gets upset.
Eventually, Gordon, who is feeling embarrassed, is stopped and brought back. But by now Edward is late, so he sets off instead. This causes more trouble, as the signalman at the junction is not told about the change and sends Edward down the main line. When Gordon follows, he is sent down the branch and ends the evening by being forced to sleep in a siding near the harbour.
The next morning, Bill and Ben arrive to pick up trucks from BoCo. While neither BoCo nor the trucks are there, they do not mind as they much prefer the idea of teasing Gordon. After joking that the large blue engine near them cannot be Gordon, as Gordon would never goes on branch lines as he thinks them vulgar, they pretend to consider throwing the pile of old iron into the sea. Gordon, not knowing it is a joke, starts to panic.
BoCo then arrives and Gordon begs the diesel to save him. BoCo soon realises what is happening and threatens to take the trucks away. Bill and Ben quickly run off, as a relieved Gordon thanks BoCo for saving his life.
