Walt Disney, the creator of the concepts for Disneyland and the Disneyland Railroad, always had a strong fondness for trains. As a young boy, he wanted to become a train engineer like his father's cousin, Mike Martin, who told him stories about his experiences driving main-line trains on the Atchison, Topeka and Santa Fe Railway. As a teenager, he obtained a news butcher job on the Missouri Pacific Railway, selling various products to train passengers, including newspapers, candy, and cigars. Many years later, after co-founding the Walt Disney Company with his older brother Roy O. Disney, he started playing polo. Fractured vertebrae and other injuries led him to abandon the sport on the advice of his doctor, who recommended a calmer recreational activity. Starting in late 1947, he developed an interest in model trains after purchasing several Lionel train sets.
