Eddie is busy and Hodge can't help him. Then Eddie goes off on another job, to unblock the coal chute. Hodge is still upset. Then Zephie shows him an invention of Dr. Ling's, The Chugnav. It, from a satellite above, can tell a chugger which way to go. Then Wilson gets stuck on the track lift and Hodge must collect a part from a very far away destination, in which he doesn't know the way. So Hodge uses the Chugnav. On the way to the destination, Hodge meets Action Chugger. Action Chugger wants to find the satellite and goes up and knocks the satellite upside down. The Chugnav now doesn't work properly and Hodge can't find his way home. Action Chugger soon realised his mistake and takes Hodge to fix the satellite, when the satellite was pointed to Chuggington, they go home and Eddie fix the track lift.
- This is the first time Action Chugger (and Hodge) goes into space.
