We’ve invested in the 8 Av Line Signal Modernization project—an initiative which will solve the ongoing delays caused by old signals along the 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.
We are continuing the installation of the CBTC system through 2024. Service changes began again in early 2021, affecting service in one or both directions between 59 St-Columbus Circle and Jay St-MetroTech and will continue some weeknights and every weekend (except for Thanksgiving and Christmas) through the end of the year.
More reliable transit
The installation of CBTC Signaling on the 8 Av 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 are a leading cause 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
trains will run local or trains will run express in either direction between 59 St-Columbus Circle and Canal St.
trains will run express in either direction between 42 St-Port Authority and Canal St. and tt trains may run via the in either direction between W 4 St-Wash Sq and Jay St-MetroTech
As alternatives for 8 Av, use nearby 7 Av stations, or 6 Av stations.
When trains are rerouted via the line, use the between W 4 St-Wash Sq and Chambers St (World Trade Center), use the train for Fulton St via transfer at Delancey St-Essex St.
Car and pedestrian traffic may also be limited in some areas while we’re doing this work.
