“Oh yeah, [the subway] was a bold undertaking and little by little it just grew over a period of about 45 years,” historian Joe Cunningham said. He also pointed out the gaps in service: southeast Brooklyn, central and eastern Queens, straight up the middle of the Bronx. Almost all of those neighborhoods were set to get their own subways. Most of those lines died on the drafting table, but some were begun and then abandoned when the city ran out of money or pursued other priorities.
