By Candace Sutton The Queen has telephoned Australia's leading horse trainer Gai Waterhouse about her horse which races in Sydney tomorrow, with high hopes of a win for the royal stallion, Carlton House. Waterhouse, known as the 'queen of racing' in Australia, told Her Royal Highness Carlton House has been performing well in trackwork and was in great form for his race at Sydney's Royal Randwick on Saturday. Waterhouse's stable reported the Queen's horse had just 'shaded' or beaten the champion trainer's prize stallion, Fiorente, in an exhibition gallop at Randwick in late January. The Queen 'knows her horses' and is 'very much on the ball' about the Australian horse racing scene, says top Australian trainer Gai Waterhouse (right) who has prepared the monarch's stallion Carlton House for a race in Sydney on Saturday
