Storm Maker is a storm simulator situated in the training yard. It's designed to create all types of weather and only responds to Dunbar's voice command. In the episode Wilson and the wild wind, Wilson told it to make a strong wing at level 300. It did just that and nearly created a storm in chuggington. Luckily, Wilson hooked up to Koko and Brewster and together they were able to stop it. In the episode Magnetic Wilson, Dunbar used it for advanced storm training. Koko said that they should skip a few levels to have time for chugtag. Wilson told it to make a hurricane at level 30 and it blew Koko off the track. When it stopped Koko hit the ground and damaged a wheel.
It has also made cameos in various episodes
