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.
