NEW YORK, NY March 18, 2007 —Service on the number 7 subway line was back to normal this weekend, in order to accommodate St. Patrick’s Day revelers. But it's just a brief reprieve; service from Queens to Manhattan will be suspended again over the next few weekends. The signal system on the Seven Line is getting a 21st century upgrade. As WNYC’s Beth Fertig reports, the subways still rely mostly on mechanical systems whose origins date back a century.
