First roller coaster opened in 1884. The “Gravity Pleasure Switchback Railway” of Coney Island dropped 50 feet, and the mechanism traveled six miles per hour. It cost a nickel to ride.
Escalator was patented in 1892 by Jesse Reno of New York City. He used his escalator as a ride at Coney Island. Later, by about 1910, the escalator was developed as a mode of moving people.
