Koko, Wilson and Brewster try for their fire safety badges, but when the alarm sounds, will they remember the rules for evacuating a burning building?

To earn his badge, Wilson must show that he knows how to recognise destination icons. He gets distracted by following a butterfly and totally forgets where he is supposed to be going. After running around to some wrong locations, he finally concentrates really hard, and remembers he was supposed to be going to the foundry.

Brewster and Wilson compete to earn their 'Helping Wheels' badge. However they get so caught up trying to outdo each other, that they don't help anyone. Koko beats them to it, winning her badge by helping a little girl rescue her kite. In the end, Wilson and Brewster help each other out and decide to work together as a team to earn their badge.

To earn their badges, Koko and Brewster must keep to a schedule picking up passengers. Koko is too eager and gets ahead of schedule, while Brewster is too cautious and gets behind schedule - but in the end, they both learn to run on time!

Brewster is given the task of keeping Ebo occupied while some work is done to his enclosure at the Safari Park.

To earn their badges, the trainees must devise a fitness routine. Wilson climbs on the train jack and has Lori move him up and down. But Lori points out that she is the only one getting a work out! When Wilson tries to move off the jack his wheels spin and spin and he discovers it's the perfect 'stationary bike' for a chugger! He demonstrates his wheel work out and wins his badge.

To earn their star map badges, Koko, Brewster and Wilson must find patterns in the stars and follow them. Wilson has some trouble, but ends up succeeding.

To earn their badges, Wilson and Brewster must rescue Emery, who will pretend to be broken down in a tunnel. They spend so much time bickering that a fed up Emery drives off. It looks like Wilson and Brewster won't earn their badges - until there's a power cut causing a real emergency. They work together and rescue a now genuinely stranded Emery!

To earn her badge, Koko has to deliver two different types of cargo safely. She goes too fast and nearly breaks her cargo of eggs - then goes too slow, and is nearly late with her cargo of wool. Happily, she realises that different cargos need different delivery methods: slow and steady with the eggs, but faster with the wool. Learning the difference means that she wins her badge!

To earn their badges, the trainees have to play a game. They have to find 'pairs' of chuggers behind different-coloured roundhouse doors. Koko and Brewster do well, but easily-distracted Wilson fails the first time around. After a pep talk from Vee, he applies himself - and by concentrating really hard, he wins his badge!

Koko is put in charge of Wilson and Brewster. The team has to complete a newspaper round by a certain time. Koko nearly fails and learns that being bossy isn't the best way to lead. She tries again, using her team members' strengths instead and in the end shares her badge with Wilson and Brewster. After all - they're a team!

The trainees have to assess each other as they do braking tests in the park. Wilson doesn't do so well - and the trainees consider reporting that he did better than he actually did. In the end, Wilson decides they should be honest to Vee, even if it means forfeiting his badge - but Vee tells them the badge wasn't for braking, but for good judgment, which they've shown by telling the truth!

To earn their badges, the trainees must be efficient when picking up litter, which means not wasting any time. Wilson and Koko race off, each determined to finish first. Methodical Brewster goes more slowly, sorting the litter as he goes into 3 different bins: paper, plastic and cans. Koko and Wilson deliver their messy loads to the recycling yard - but it won't count until it's sorted! While a happy Brewster collects his badge, Koko and Wilson are still sorting their litter...

Wilson, Koko and Brewster need to keep quiet for a whole day.

Koko washes down platforms, Wilson picks up litter and Brewster paints some old fences in order to gain their "Keep Chuggington Beautiful" badges.

Brewster and Wilson must give their badge away to someone they appreciate, but with so many friends, it's no easy task.
