F trains will not stop at any stations that are south of Church Avenue on weekends from Fridays at 9:45 p.m. to Mondays at 5 a.m., starting on Friday, March 20th, and ending on Monday, December 21st.
Northbound F trains will run from Church Avenue to 179th Street. Southbound F trains will run from 179th Street to Church Avenue. F trains will not make either northbound or southbound stops from Ditmas Avenue through Coney Island-Stillwell Avenue.
These stations will be closed:
- Church Avenue (no southbound service; northbound service will be available)
- Ditmas Avenue
- 18th Avenue
- Avenue I
- Bay Parkway
- Avenue N
- Avenue P
- Kings Highway
- Avenue U

Service will be normal on major holidays and some other days:
- Easter/Passover: April 10th through 13th
- July 4th weekend: July 3rd through 6th

- Thanksgiving weekend: November 27th through 30th
- the weekend after Christmas: December 25th through 28th.
The project will modernize the seventy-year-old signals currently in use. A “Communications Based Train Control” (CBTC) system will be installed on this section of the line and new signal facilities will be added at Ditmas Avenue, Bay Parkway, and Avenue X. The project will allow MTA personnel to respond faster and provide alternative service options in case of service disruptions.
Free shuttle buses and alternate train service will be available at F train stations from Church Avenue to Coney Island.
When it is beach season (May 23rd through September 14th), a free express shuttle bus will go directly from Church Avenue to Coney Island-Stillwell.
Work will continue in 2021, but details have not been released yet.
