The Duchess of Sussex will join the Queen on her private train to travel to her next official engagement - something which Harry, William and Kate have never been invited to do.
It's believed that the trip will take them overnight, departing on Wednesday and arriving at Runcorn Station in Cheshire on Thursday morning.
It's not every day that a member of the royal family gets to make the special journey with the Queen. Royal Central reports that the train is usually only available to senior royals including Prince Philip, Prince Charles and the Duchess of Cornwall. While William and Harry may have used the train, it's understood that they have never boarded it with their grandmother, reports the Metro.
The luxury train apparently features a bedroom, bathroom and sitting room, while afternoon tea and light refreshments can be served in the dedicated dining coach.
The visit - Meghan's first official outing without Harry by her side - will include opening the Mersey Gateway Bridge and visiting the Storyhouse theatre and library.
