a lot of service changes took place with the start of full service on the t third street line on april 7, 2007. the new line was routed through the subway to castro station. it replaced the s castro shuttle; changes were also made to the j church, n judah, and several bus lines. the changes were unpopular with the public; the muni metro changes caused big delays in the market street subway, and forced many users to transfer to reach the caltrain station when they did not back then.
