The MTR Corporation has ordered a larger-than-life birthday cake to help celebrate the 25th anniversary of Hong Kong's urban rail network on October 1. The decoration, about 5 metres across and 3.4 metres high and made of fireproof material, will be displayed at Hong Kong Station from the middle of next month until the beginning of October. 'It's a special cake decorated with models of our urban trains, the Airport Express, Two IFC, Octopus card and tickets,' said Jeny Yeung Mei-chun, general manager, marketing and station business. 'Our riders will instantly recognise it as the MTR's birthday cake,' she added. Banners designed by children have been commissioned to show what the railway means to Hongkongers, 25 years after the Shekkipmei to Kwun Tong section opened on October 1, 1979. 'We're hoping that the birthday cake will be a highlight and photo opportunity for locals and tourists alike. It will be a celebration of our past 25 years and offer something for them to remember our anniversary by,' Ms Yeung said. A television documentary on the MTRC's history has also been completed for airing on TVB Jade, beginning on Monday. There will be 20 episodes, running for one minute a night at 10.35pm. The rail operator also will issue a commemorative set of four souvenir tickets, each depicting the growth of the rail network over the past quarter century on one side and a picture of an important MTRC development on the other. These pictures include development of the Two IFC tower in Central, various trains and the new Tsim Sha Tsui station design. Purchasers of the $150 special ticket set, which can be used for travel, will receive a commemorative booklet on the company's history and a model train decorated with the 25th anniversary livery.
