- “Oh. Hi Thomas.”
- ―Lei after flipping upside down.
Runaway Car in North America, is the seventeenth episode of the twenty-second series.
In China, Yong Bao is chasing a runaway box van named Lei down the mountain in an attempt to stop him. Thomas is nearby and decides to try and stop Lei himself. Yong Bao is about to stop Lei when Thomas intervenes and rams into Lei at full force, derailing him. Yong Bao is annoyed that Thomas used force to stop Lei and likens the method he was going to use with tai chi, a Chinese martial art. He tells Thomas he will show him at the town square in the morning and leaves to get a crane. The next morning, Thomas collects some trucks and meets Yong Bao in the square, where several people are all practicing tai chi in unison. Yong Bao points out the way the people are all moving together and suggests that instead of crashing into Lei and derailing him, Thomas should have backed up with him and slowed him down. At the shunting yard in the mountains, Yong Bao, Thomas, and Lei all begin practicing. Yong Bao demonstrates by reversing as Lei is coming towards him, moving with him to slow him down instead of using brute force. Thomas derails Lei several times before eventually stopping him. They are about to try again, but a signalman accidentally leaves the points set to the main line instead of Yong Bao's track, causing Lei to careen down the mountain. Thomas rushes after him. Thomas chases after Lei and switches tracks so he can pass him, but a rock on Lei's track causes him to be thrown onto Thomas' line. Thomas finds a passing loop that allows him to get in front of Lei. Remembering Yong Bao's advice, Thomas gradually slows down instead of braking sharply, allowing him to stop Lei safely. Yong Bao catches up with Thomas and congratulates him for mastering the core principle of tai chi: moving with the flow of energy instead of against it.
