From the NY Times:
The Main Street station on the No. 7 line, in Flushing, Queens, made a rare appearance last year in the coveted New York City Subway Top 10: the 10 most heavily trafficked stations in the underground, according to ridership data released by the Metropolitan Transportation Authority.
More than 18.6 million passengers streamed through the station’s turnstiles in 2010, in a uptick of nearly 2 percent from 2009. That was enough to bump last year’s No. 10 station, the Fulton Street complex in Lower Manhattan, down a notch to No. 11.
And we're planning to put hundreds of thousands more people along the line?
