Prince Harry has recorded a special message to celebrate the 75th anniversary of children’s favourite Thomas the Tank Engine.

The Duke of Sussex introduces a new programme called ‘Thomas and Friends: The Royal Engine,’ which has a storyline that includes Harry’s father and grandmother, Prince Charles and Queen Elizabeth II, as animated characters.

Set when the Prince of Wales was a boy, the story sees the friendly engine taking Sir Topham Hatt, the controller of the railway, to Buckingham Palace to receive an honour.

In his introduction — which was recorded in January before his move overseas — Prince Harry is seen sitting in an armchair, reading from a book about the train’s adventures.

In a statement he said he has “fond memories of growing up with Thomas and Friends and being transported to new places through his adventures.”

Thomas “has been a comforting, familiar face to so many families over the last 75 years — entertaining, educating and inspiring children on important issues through exciting stories and characters,” he added.

In January, Prince Harry and his wife Meghan, the Duchess of Sussex, announced they planned to quit as senior royals, seek financial independence and move to North America.

The split became official at the end of March, and the couple are currently in California, where Meghan was raised.
