Oakland's first horsecar line was built in 1869 and ran along Telegraph Road to 36th Street. It was extended to Temescal a year later, then to the university campus via Humboldt and Choate after the university relocated from Oakland in 1873. A business district grew up along Choate Street. The horsecar line was eventually replaced by a steam dummy line, and later by an electric streetcar line. This transportation corridor stimulated the development of neighborhoods along its route, as well as an amusement park, Idora Park, between 56th and 58th Streets.
