Luke

Luke is an Irish narrow gauge tank engine and one of Thomas and Pooh's best friends. Luke arrived on Sodor from Ireland. It had always been his dream to join the Sodor railway. When Luke arrived on Sodor, he hid out of shame believing that he caused Victor to fall into the sea. With Thomas and Pooh and his friends' help, Luke learned the truth and was able to stop hiding. Tigger refers to him as "Lukey boy", which Luke likes that nickname very much.
