50 free Thomas the Tank Engine trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Thomas the Tank Engine began as a broomstick toy an Anglican vicar whittled for his son during a bout of measles. Wilbert Awdry's stories became The Railway Series in 1945, Thomas arrived in the second book in 1946, and in 1984 Britt Allcroft mortgaged her house to put him on ITV with a Beatle reading the narration. Over 500 episodes, two reboots, a Mattel buyout and a film that flopped later, he is still the most famous locomotive in the world. This quiz digs into the whole world of Sodor: where the island sits, what language its people speak, which Welsh railway inspired the Skarloey line, why the Fat Controller used to be the Fat Director, which illustrator Awdry fell out with, and how a firefighter taxi driver was briefly cast as the voice of Thomas. Fifty questions, from the basics every parent knows to the details only a true Sodor historian would recognise, served in sets of ten.
