Fredrik competed at The Great Railway Show. He competed in the shunting competition, alongside Emil, Ashima, Ivan, Thomas, Gina, Raul, Philip, Rosie, and Madison. He was the only tender engine to compete in the shunting competition, which prompted some teasing from Gordon, Marie, and Spencer. Brady defended him, and the two became friends.
Fredrik is quiet and shy. He is often teased by other engines, and because of this, has little self-confidence.
Fredrik is based on a Swedish State Railways Class A 4-4-2 tender engine. Only 26 of these locomotives were built and 17 were scrapped.
For the Great Railway Show, Fredrik was painted blue with yellow lining and with the Swedish flag on his tender.
It was later revealed that, both before and after the Great Railway Show, Fredrik was painted seaweed green with black lining.
- Fredrik's colours at The Great Railway Show are based on the colors of the Swedish flag.
