The duchess and the Queen were met by David Briggs MBE, the Lord-Lieutenant of Cheshire after stepping off the train.
He told the duchess: "Welcome to Cheshire. I understand this is your first visit to northern England."
The duchess, wearing an outfit by Givenchy and clutching a handbag, replied: "That's right yes."
A body language expert says there was genuine warmth between the pair.
The Duchess of Sussex turned to Givenchy to create the outfit for her all-important first joint engagement with the Queen.
The Queen and the Duchess of Sussex fell silent to mark the first anniversary of the Grenfell Tower tragedy.
