By the 1970s and 1980s, the New York City Subway was at an all-time low. Ridership had dropped to 1910s levels, and graffiti and crime were rampant. Maintenance was poor, and delays and track problems were common. Still, the NYCTA managed to open six new subway stations in the 1980s, make the current fleet of subway cars graffiti-free, as well as order 1,775 new subway cars. By the early 1990s, conditions had improved significantly, although maintenance backlogs accumulated during those 20 years are still being fixed today.
