Thomas is told to take the circus train and to share the load with another engine because of its weight, but Thomas is so excited to be pulling the train that he wants the glory all to himself, and turns down offers of help from Salty, Percy and James. This turns out to be a bad decision when Thomas' siderods break from the strain. Luckily, Percy and James come to help and the three deliver the circus to the grounds on time.
