It might not be last weekend's subway hell, where almost all 20 subway lines were diverted due to much-needed service work, but there are still many diversions planned for this weekend. For instance, NYC Transit says for the 1, 2, 3, 4, 5, 6, and L lines, "Due to necessary maintenance work customers may experience 5 to 7 minute delays from the times listed in the published timetable" (hee, published timetable!) and "D Trains run local in both directions between 34 St-Herald Sq and West 4 St" (which is admittedly better than not running at all). Here are service advisories for today and tomorrow.
