The buses were officially launched in the week of the 70th anniversary of the Queen’s accession to the throne, which took place on 6th February 1952.
The platinum jubilee buses will be seen across the year, on services throughout Hampshire, Surrey and West Sussex.
Managing Director of Stagecoach South, Edward Hodgson commented: “The whole nation and our commonwealth countries are gearing up for a big celebration in June and we felt that it was important for us to honour this historic milestone within the communities we serve.
“We are therefore proud to mark the Queen’s Platinum Jubilee, with these two special buses that will be used throughout the year on our local bus networks.
Steve Thorpe, Marketing Officer for Stagecoach South said “This is such an historic moment, as it is the first time that any British monarch has attained 70 years on the throne.
“We hope that our customers and residents across the area will enjoy travelling on, and seeing, the jubilee buses on the streets throughout the year.”
The jubilee themed buses will initially enter service at Andover depot in Hampshire and Worthing depot in West Sussex, before commencing a tour of the other 6 depots throughout the South region during 2022.
