More summer holidaymakers are flocking to Sodor, but Thomas and Emily are being repaired, so no-one is running the branch line. The Fat Controller goes to Bulgy, who is delighted to be put back into service. Bulgy is restored and is brought back to his old field for the night. The hens miss their home and creep aboard in his luggage racks, without Bulgy noticing.

Skarloey is often delayed as he has to take workmen to repair the line, and the Fat Controller is worried he may be late to the opening of the new station.. Harold has engine trouble, so the Fat Controller and Lady Hatt choose to ride the hot air balloon instead. The balloon's burner runs out of fuel, but they land in a tree next to Skarloey, who takes them to the grand opening.
