Playland Park was an amusement park located in Houston, Texas operating between 1940 and 1967. Louis Slusky opened Playland Park circa 1940 at 9200 South Main. It is popularly remembered for its wooden roller coaster, The Skyrocket. Texas’ first elevated monorail train (1956) briefly operated near the park. Next to the park was an adjoining stock-car race track known as Playland Speedway. Slusky also facilitated the miniature children’s train located in Houston’s Hermann Park. This train may have originated from Playland Park. Playland Park closed in 1967.
