Over 26 million passengers have used the tram since it began operation in 1976. Each cabin has a capacity of up to 110 people and makes approximately 115 trips per day. The tram moves at about 17.9 mph (28.8 km/h) and travels 3,100 feet (940 m) in 3 minutes. At its peak it climbs to 250 feet (76 m) above the East River as it follows its route on the north side of the Ed Koch Queensboro Bridge, providing views of the East Side of Midtown Manhattan. Two cabins make the run at fifteen-minute intervals from 6:00 a.m. to 2:00 a.m. (3:30 a.m. on weekends) and continuously during rush hours. It is one of the few forms of mass transit in New York City not run by the Metropolitan Transportation Authority, but uses that system’s MetroCard and has free transfers to that system.
