History: The New York City Subway, United States

“The New York City Transit (NYCT) is a subdivision of the Metropolitan Transportation Authority (MTA) that operates the city's subways and buses. The NYCT authorizes these types of free expression in subway stations: "Public speaking; distribution of written materials; solicitation for charitable, religious or political causes; and artist performances, including the acceptance of donations.”
Performers must not be within 25 feet (7.6 m) of a token booth or 50 feet (15 m) from a MTA office/tower, blocking access to an escalator, stairwell, or elevator, interfering with transit services or passenger movement; or in an area where construction is occurring. In addition, performance is prohibited during public service announcements and may be no louder than 85 dBA at 5 feet (1.5 m) away or 70 dBa at 2 feet (0.61 m) from a token booth. Performances are prohibited in subway cars.
• Restrooms
Restrooms are rare in the subway system as only 129 open restrooms are in 77 of the system's 468 stations. Most station rest rooms previously open to the public have been closed to the public and converted to storage spaces or for employee use only. However, there are a few major stations that have operating restrooms, including on the concourse of 42nd Street – Port Authority Bus Terminal, Chambers Street, 57th Street, Coney Island – Stillwell Avenue, and Lexington Avenue / 59th Street.
