a lot of service changes took place at the time when the t third street line began service on april of 2007. the n judah was cut back to embarcadero station; the surface part on the embarcadero was served only by the t third street line, plus the j church line at peak hours. the changes were unpopular with the public; they caused big delays in the market street subway and made n judah riders transfer to reach the caltrain station when they did not before. on june 30, 2007, muni reversed several of the changes; the j church and n judah were put back to their previous routes.
