It became known as The Great Train Robbery . At one stage during the hunt for the thieves , suspicion fell on Winterfold House above Cranleigh where a police raid took place searching for some of the train robbers , but nothing was found . Later in the same vicinity some of the proceeds were discovered : £ 100,900 in a bag in Redlands Wood , a beauty spot two miles from Dorking , and a further £ 30,435 in a caravan on Box Hill Surrey
