 This resulted in service changes to the 1, 2, and 3 routes and led to reduced service in Manhattan and Brooklyn until the WTC section of the line reopened in September 2002.Concurrent with the rebuilding of that section of the line, MTA officials recognized the need to build a more efficient terminal for the 1 and 9 trains at South Ferry, since it was anticipated that the line would be heavily used in the long-term aftermath of the attacks.This also coincided with the renovation of Battery Park.
