Anxious, Little, Big, and Happy loved at the Workshop with Percy before arriving to Sodor on trial. Sir Topham Hatt came to the Workshop to purchase a engine, when the big engines went on strike and Thomas left to run his branch line. Sir Topham Hatt decided to give all five engines a chance, so they all went to Sodor on trial. When Sir Topham Hatt had to choose one engine he decided to keep Percy. Anxious, Big, Little, and Happy were sent back to the Workshop until they were purchased by The Other Railway where they currently work.
