Rail transport can be found in every theme park resort property owned or licensed by Walt Disney Parks and Resorts, the theme park and vacation resort segment of the larger Walt Disney Company.
 The origins of Disney theme park rail transport can be traced back to Walt Disney himself and his personal fondness for railroads, who insisted that they be included in the first Disney park, the original Disneyland (a key component of the Disneyland Resort) in California in the United States, which opened on July 17, 1955.
 The Disney tradition of including transport by rail in its parks has since been extended to other Disney properties with the opening of Walt Disney World in Florida in the United States, Tokyo Disney Resort in Japan, Disneyland Paris in France, Hong Kong Disneyland Resort in China, and Shanghai Disney Resort in China.
