Passengers traveling on trains in Britain, at the beginning of next week during the coronation of King Charles, will hear a special message recorded by the king himself. The message includes a reminder to "beware of the gap" between the platform and the train carriages. King Charles states in the message, "My wife and I wish you and your families a wonderful weekend and coronation," followed by well wishes for a happy journey from Camilla, who says, "Wherever you go, we hope you have a safe trip." Charles will then say, "Remember, please beware of the gap," referring to the distance between the platform and the carriages. This phrase will be familiar to the ears of Britons and visitors, as it is also used in some train networks in other English-speaking regions around the world. This recorded message will be heard on the London Underground network between Friday and Monday.
