MTA Launches $1.9B Subway Signal Upgrade on A/C Lines, Benefiting 350,000 Daily Riders
Governor Hochul announced Oct 22 the MTA's largest-ever signal and track replacement program: $1.9B, funded by congestion pricing revenue; 42 miles of track and 23 stations on the Fulton and Liberty lines get 1930s signals replaced with CBTC, completion expected Q2 2032.
Why it matters
This is the largest such project in MTA history. Governor Kathy Hochul announced on Oct 22 a $1.9B investment funded by congestion pricing revenue. MTA Chair Janno Lieber said signal failures are the top cause of subway delays; the new system will let trains run closer together, faster and more reliably.
The work covers the Fulton and Liberty lines from High St in Brooklyn to Ozone Park–Lefferts Blvd in Queens: 42 miles of track and 23 stations, replacing 1930s-era signals with communications-based train control (CBTC). The corridor carries about 350,000 daily riders; the A/C lines overall carry about 750,000, connecting with 7 subway lines, 36 bus routes and the LIRR.
Full report
The first phase replaces switches and track between 104 St and 99 St in Queens, with full completion expected in Q2 2032. For daily A/C commuters, the 1930s-era signals are finally headed for retirement — but the next decade will bring staged construction, so riders should watch for reroute and service-change notices.
