Brewster is a strong and solid diesel-electric train built for heavy loads. He doesn't always understand his own strength, which can make him a bit awkward and clumsy. Other trainees may want to rush into action when they've been given a mission, but sensible Brewster asks questions first. He is very dependable and can always be relied on in a crisis; he's a tower of strength. One of his catchphrases is "Honking horns!"
