Tilden Park Merry-Go-Round, Historic carousel in Contra Costa County, US

Tilden Park Merry-Go-Round is a menagerie carousel built by the Herschell-Spillman Company of Tonawanda, New York, in 1911. It has four rows of animals: the outer three rows carry hand-carved poplar figures, while the innermost row consists of cast aluminum figures added in 1950. The ride retains its original 7-1/2 horsepower Westinghouse electric motor and is operated with a trolley car throttle and manual handbrake.

The carousel was built in 1911 by the Herschell-Spillman Company and traveled to various locations throughout California. It became permanently installed at Tilden Park in 1948, where it has remained ever since.

The rounding boards carry vignette paintings made in 1950, when the ride was rebuilt as a four-row machine and the original boards were replaced with the white ones seen today. The inner row of horses is cast aluminum, while the outer figures are hand-carved poplar. A North Tonawanda band organ stands at the centre.

The ride runs weekends year-round and on weekdays from Memorial Day to Labor Day and during Spring Break, normally 11am to 5pm, with summer weekend closing at 6pm. A night-time Christmas event runs from Thanksgiving to Christmas. On weekends AC Transit line 67 stops at Lake Anza/Merry-Go-Round.

The ride still runs on its original 7½-horsepower Westinghouse electric motor, controlled by a trolley-car throttle and a manual handbrake. Its North Tonawanda band organ, overhauled in 2008, was still not operating as of March 2016.
