As People reports, Kate and William will stop in towns and cities across England, Scotland, and Wales, staying overnight on the train, in order to thank those working on the frontlines of the COVID-19 pandemic. They'll meet with "frontline workers, volunteers, care home staff, teachers, schoolchildren and young people," according to the magazine.

A spokesperson for the Cambridges told People, "The Duke and Duchess are very much looking forward to shining a spotlight on the incredible work that has been done across the country throughout this difficult year and to sharing their gratitude on behalf of the nation for all those supporting their local communities ahead of the Christmas holidays." 

Kate and William started their tour at London's Euston Station, meeting transport workers and enjoying a performance of "Merry Christmas Everyone" by Shakin' Stevens (spot Kate dancing in the clip above). Speaking to Transport for London area manager Alero Abbey, Hello! reports, William said, "It's moments like this when people really appreciate what you do every day. Suddenly we all know what you do and that you do a really good job."

Kate also left a festive message on a service information board at the station, to which William added his signature. " Thank you to transport workers everywhere for keeping the country moving throughout this difficult year," she wrote. "Wishing you all a very Merry Christmas!"
