RM1288 (Hong Kong #1) and RM1873 (Hong Kong #2) were sent to Citybus to attend the "British Exhibition" held at the New World Center in Tsim Sha Tsui in 1984. In 1985, the rear stairs and the boarding platform were swapped left and right to make them suitable for left-hand drive traffic in mainland China. After the completion of the project, RM1288 and RM1873 were shipped to Guangzhou and Beijing respectively for promotion purposes, hoping to find further uses for the Routemaster, which was being retired from London at the time.[citation needed] RM1288 was withdrawn in 2015, sold to Great European Carnival (HKGEC) and then preserved at Kam Tin campsite in Forest Valleyland.[1]
