From the Brooklyn Paper:
Greenpoint will be cut off from the rest of the city late on weekend nights, as the Metropolitan Transportation Authority eliminates the G train for the next four weekends. The agency says that the nighttime weekend service cut is to accommodate track work and station repair until Feb. 8. Shuttle buses will replace the G train — dubbed “the Brooklyn local” after the MTA extended it all the way to Church Avenue last year — between 10:30 pm and 5 am on Fridays, Saturdays and Sunday. The F train will operate normally between Church Avenue and Bergen Street during those hours.
