Improving Service Reliability on the 123: Switch Replacement at 96 St

Significant Weekend Service Changes: July 19 to August 26

We have intense and essential work to maintain the reliability and safety of the track switches north of the 96 St 123 station. The switches were last replaced in 1990, and are near the end of their useful life. Watch our video to learn more, and read on for detailed subway and bus alternatives including accessible travel information.

    What’s Happening?

    We're completely replacing the switches at 96 St between the uptown local and express tracks. This intense work requires us to completely remove the switches and surrounding track, pour new concrete, and install new track along with the new switches. We need uninterrupted access to both tracks and track bed for the work to be done safely and quickly. Once replaced, the new, modern switches will help us run more reliable service.

    Phase 3 will take place August 16-19 and August 23-26, when there will be a full suspension of service at 123 stations between Harlem and Downtown Brooklyn. During this suspension, we're also doing vital work along the entire 123 line:

    • Installing new track and repairing existing track and track beds to provide a smoother, more reliable ride.
    • Cleaning drains all along the line to help prevent flooding that can cause train delays.
    • Repairing signals to improve their reliability.

    During each weekend, we'll provide alternative service options so that you can get where you need to go, including free, frequent shuttle buses connecting affected stations and extended 4 service into Brooklyn. During the line service suspensions in Phase 3, we'll run M trains up the west side to 145 St. Below is a list of every service change, separated by phase.
