Hi I have been to Windsor Dog Show many times by train, its a doddle!!. From Portsmoth or Southampton you will arrive at London Waterloo. Then all you need to do is get the Windsor and Eton Riverside train, they run every half an hour and the journey takes about 40 mins. Get off at Windsor and Eton Riverside. Then it is about a 10 minute walk. By the way turn left outside the station, dont head into the town.
hth AND ENJOY YOUR DAY..
Anna
