Bringing CBTC to the 8 Av Line

We’re modernizing the signaling system on the 8th Ave Line between 59th & 8th Ave in Manhattan and High Street in Brooklyn. 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 8th Ave Line Signal Modernization project—an initiative which will solve the ongoing delays caused by old signals on the 8th Ave Line by fully replacing them with modern signaling. This will provide enhancements to service on the lines when the Signal Modernization project is complete.

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

We are continuing to install CBTC system throughout 2021 through 2024. Service changes began again on January 8, 2021, and will continue roughly every weekend through August 2021 in the north and southbound direction of service


More reliable transit

The installation of CBTC Signaling on the 8th Ave line especially in the Central Business District (CBD) will increase the existing throughput versus the old signal system which is nearing 80 years old. Problems with the old signal system is one of the leading causes of service disruptions.

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.

Service changes and alternative travel options

During the 8th Ave Line improvements, there will be no local or express   train service at these stations on impacted weekends (every weekend through August, 2021)
