Once again, this coming weekend — 10:45 PM tomorrow (Friday, December 15) to 5:00 AM Monday, December 18 — there will be no 2 and 3 train service (meaning no service at Clark Street or on the 2/3 platforms at Borough Hall), which will be a fact of life every weekend until sometime next summer. As usual, during the absence of 2/3 service, 4 an, d 5 (5 trains don’t usually serve Brooklyn on weekends) will provide alternate service to and into Brooklyn. Also this weekend — from 9:45 PM Friday to 5:00 AM Monday — there will be no service in either direction at Court Street or on the R/N platforms at Jay Street-Metro Tech, as R and N trains are being diverted to the Q line between Canal Street and DeKalb Avenue. With no 2/3 or R/N service, your options this weekend are limited to 4/5 at Borough Hall, A/C at High or Jay Street, or F at Jay.
The following work week — Monday, December 18 to Friday, December 22, preceding the Christmas weekend — each night from 9:45 PM to 5:00 PM there will be no service in either direction at the 4/5 platforms at Borough Hall, as 4 trains will terminate and originate at Brooklyn Bridge in Manhattan, and 5 trains don’t serve Brooklyn during these hours. During these same late night hours A trains will be diverted to the F line in both directions between West 4th Street and Jay Street. This means no service at High Street, as C trains don’t run late at night. During these late hours, your options are the 2 at Clark Street or Borough Hall, the N (the R doesn’t run late) at Court Street, or the A or F at Jay Street or York Street in DUMBO.
