Elizabeth II (born as Elizabeth Alexandra Mary) has been Queen of the United Kingdom since 1952.
Elizabeth II first met Sir Topham Hatt in 1952, when he was presented to her by his son-in-law, Henry Regaby, the Governor of Sodor. Elizabeth II first appeared to meet the residents of Sodor after her coronation. Gordon was honoured by pulling her train and Thomas sorted the coaches for it, while Edward cleared the line ahead. She was greeted and honoured by Sir Topham Hatt at Tidmouth, and told the controller that she had a splendid run and wanted to meet the engines.
When Emily asked Gordon what kind of specials he took, he mentioned the time he pulled Elizabeth II's Royal Train.
In a Really Useful Around the World segment for the Thomas' YouTube World Tour, Thomas had to collect Elizabeth II in London; but he did not realize this when she boarded the train, as he was so bowled over by all his other important looking passengers.
Elizabeth II also appeared in a special book, A Visit to London for Thomas the Tank Engine, to commemorate her 90th birthday, in which she invited Thomas, Annie and Sir Topham Hatt to her birthday celebration.
- Elizabeth II appeared as an allusion to her coronation in the same year the book was published. The Reverend W. Awdry had also sent the royal family Railway Series volumes to read to the young Prince Charles and Princess Anne.
