In the United States, trolley parks, which started in the 19th century, were picnic and recreation areas at the ends of the trolley lines , created by the trolley companies to give people a reason to use their services on weekends. These parks consisted of picnic groves and pavilions, and often held events such as dances, concerts, and fireworks. Many eventually added features such as carousels, ferris wheels, and other rides. However, with the increasing number of automobiles in use, trolley parks gradually declined and some disappeared. Others survived and developed into amusement parks.
Note: the light-rail vehicle known in the USA as the trolley is known in some other countries as the tram, trolleybus or streetcar. In Britain, a "trolley park" is a holding area for supermarket trolleys (called shopping carts in the USA).
