A replacement of the switches at 96 St between the uptown local and express tracks. Once replaced, the new, modern switches will help trains run more reliable service.
In the run-up to the service suspension at 123 stations between Harlem and Downtown Brooklyn, construction that doesn’t require a full shutdown will begin. That’s why there will be some service changes on the following weekends:
Phase 1: July 19-22 and July 26-29
Phase 2: August 2-5 and August 9-12
Phase 3 will take place August 16-19 and August 23-26, when there will be a full suspension of service at 123 stations between Harlem and Downtown Brooklyn. During this suspension, vital work will be done along the entire 123 line.
Note: These weekend service changes will begin late Friday evening and end at 5:00 AM the following Monday.
