from New York University concluded that in the event of a nuclear attack, the 190th Street station would provide adequate shelter from fallout. This was ascertained after the researchers conducted tests on cosmic rays inside deep subway stations in the area. The 190th Street station is mostly unchanged from its original design. On March 30, 2005, the 190th Street station was listed on the National Register of Historic Places. The station was considered historically and architecturally significant as an early IND station that retained many of its original features. Elevator modifications From 1932 until 1957, pedestrians had to pay a fare to use the elevators. Though the elevators were intended for subway riders, local residents paid the subway fare to avoid climbing about eight stories up Fort Washington Hill. Bills were proposed in the New York State Legislature to put the elevators out of fare control, but these failed in committee. On September 5, 1957, the New York City Transit Authority (NYCTA) began allowing free public access to the elevators at the 181st and 190th Street stations. The NYCTA agreed once Joseph Zaretzki, the local State Senator, requested the change. In July 2003, to reduce costs, the Metropolitan Transportation Authority (MTA) announced that as part of its 2004 budget it would eliminate 22 elevator operator positions at this station and four others in Washington Heights, leaving one full-time operator per station. The agency had intended removing all the attendants at these stops, but kept one in each station after many riders protested. The change took effect on January 20, 2004, and saved $1.2 million a year. In November 2007, the MTA proposed savings cuts to help reduce the agency's deficit. As part of the plan, all elevator operators at 190th Street, along with those in four other stations in Washington Heights, would have been cut. MTA employees had joined riders in worrying about an increase in crime as a result of the cuts after an elevator operator at 181st Street on the Broadway–Seventh Avenue Line helped save a stabbed passenger. The move was intended to save $1.7 million a year. However, on December 7, 2007, the MTA announced that it would not remove the remaining elevator operators at these stations, due to pushback from elected officials and residents from the area. In October 2018, the MTA once again proposed removing the elevator operators at the five stations, but this decision
