Another weekend, another bonanza of wonky service changes that seek to make it impossible to get to your ex-boyfriend's niece's baby shower, oh no! The biggest news here is that the 1 train is suspended for significant track repair work all weekend, with shuttle buses making the rounds to-and-from some hard-to-reach stations:

For service between South Ferry and Chambers St, use free shuttle buses. Transfer between 23 trains and buses at Chambers St. 2 and 3 trains run local in both directions between Chambers St and 96 St, replacing 1 service.
· For service between 96 St and 168 St, use free shuttle buses or the AC at nearby stations.
