Henry usually pulls goods trains, but longs for a chance to pull the express.. Thomas tells Henry about the wishing tree, and Henry wishes that he could pull the express. The next day, his wish comes true, but he isn't used to coaches and gives the passengers a bad journey.

Before the construction site of a new station, there is a difficult bend. Annie and Clarabel always assist Thomas with it, but they are due for an overhaul. Thomas doesn't feel really useful without his coaches, especially when he derails at the difficult bend. However, some trucks break away and head for the new station, and Thomas has to stop them in time.
