Number One Engine is the first episode of the twenty-second series.
== Plot ==
While working on the Chinese Railway, Thomas is late picking up An An and Yin-Long. Later on when he is working on the line, he brags to them about being the fastest No. 1 engine, but Hong-Mei begs to differ that she is the No. 1 engine. The two of them decide to race together to see who is the fastest, but while racing Thomas is going too fast on a different track and is not looking, so he derails and realises how silly he is. Hong-Mei soon comes to help Thomas back onto the tracks and both the engines realise that it is okay for both of them to be No. 1 engines.
