A horsecar was an animal-powered streetcar (or tram). In the United States, during the 19th century, one of the earliest form of public transit to develop was the omnibus. These were local version of the stagecoach lines, and picked up and dropped off passengers on a regular route and without the need to be pre-hired. The omnibus was an improvement over walking. Replica horsecar lines are in operation at all Disney theme parks except Tokyo and Hong Kong as part of the parks' Main Street, U.S.A. "themed land".
