Train passengers on platforms across the UK are being reminded to “mind the gap” by the King.
Charles and the Queen Consort have recorded an announcement which is being played between Friday and Monday at every railway station across the UK and all London Underground stations, industry body the Rail Delivery Group (RDG) said.
In the message, the King begins by telling passengers: “My wife and I wish you and your families a wonderful coronation weekend.”
The message concludes with Charles adding: “And remember, please mind the gap.”
It was recorded at Highgrove earlier this year by the audio team from Transport for London.
Warnings to “mind the gap” are common at London Underground stations.
RDG chief executive Jacqueline Starr said: “The coronation is a rare and exciting event and we very much look forward to welcoming passengers with this special message.
“It’s wonderful that Their Majesties are including rail passengers as part of this historic moment.”
London’s Transport Commissioner Andy Lord said: “With less than one day to go before the coronation, we look forward to hosting Londoners and visitors from across the globe.
“We are honoured to support the celebrations with a special station announcement across our network from Their Majesties King Charles III and Queen Camilla.”
