Culver Line Signal Modernization

We’re modernizing the signaling system on the Culver Line between Church Av and West 8 St in Coney Island. For you this means more reliable transit and fewer delays. Here are details about service changes and what you can expect to improve.

We’ve invested in the Culver Line Signal Modernization project—an initiative which will solve the ongoing delays caused by old signals on the Culver Line from Church Av to West 8 St in Brooklyn by fully replacing them with modern signaling.

Here’s what you need to know about what we’re doing, how to use alternate service options as you commute, and the service improvements we expect when the project is done.

Project update

Now that the 2020 schedule of work is behind us, we are continuing to install CBTC system throughout 2021 and 2022. Service changes began again on January 8, 2021, and will continue roughly every weekend through August 2021, with the exceptions of Passover, Easter, and the July 4th weekends.


More reliable transit

We probably don’t need to tell you that the F train’s reliability is below average on this stretch of track. Problems with old signaling systems is one of the leading causes of service disruptions. Replacing this equipment—which is about 70 years old—will help us decrease delays.

More resilient transit

Modern signals will make it possible for us to have more information about where trains are and how they’re performing. Installing modern signaling means that if there are problems with the new signals, we’ll be able to troubleshoot and resolve them faster.
