The service changes are a part of the larger Culver Line Signal Modernization Project, which will add new signals, upgraded interlocking systems, and other station amenities to 12 stops along the F and G lines.
The upgrades are replacing the 70-year-old equipment that is still used in many places along Brooklyn’s subway routes, and is expected to increase travel time by as much 20 percent once completed.
For the time being however, the Signal Modernization Project will slow down travel times throughout Brooklyn.
Starting on August 30 and lasting until September 24, all express F train service will be suspended on weekdays. To address this change, G trains will be extended to the 18th Avenue stop, and will skip the 4 Avenue/9th Street, 15th Street-Prospect Park, Fort Hamilton Parkway, and Ditmas Avenue stops during rush hour, mimicking the usual F express route.
On weeknights, G trains and local F trains will run along their normal routes. Express F train service, however, will be suspended.
On weekends, Brooklyn-bound G trains will terminate at the 4 Avenue/9th Street station in Gowanus instead of progressing all the way to Church Avenue. All F trains will run according to their normal schedules on weekends.
Depending on how work on the Signal Modernization Project progresses, the MTA could potentially shorten or lengthen the time frame for these service changes. Up-to-the-minute train information can be found on the MTA’s website or the My MTA app.
Service changes are nothing new for riders of the two train lines. For two weekends in August, the MTA swapped the routes that the G and F take, allowing residents of North Brooklyn to travel all the way to Coney Island on the G Train.
The MTA saw the changes as an opportunity for good publicity, and released public statements encouraging riders to “Take the G to the Sea.”
