The MTA has reduced its subway signaling upgrade costs from $50 million to $25 million per mile by changing how it approaches contracts with contractors and eliminating the need to maintain outdated systems. By transferring more project responsibilities to contractors and fully replacing older signal systems with advanced technology, the agency aims to modernize its infrastructure following past failures highlighted during the Summer of Hell in 2017. The MTA plans to implement these advanced signals across 200 miles of track under its capital plans for 2020-2029, with the first design-build contract awarded for G train signal upgrades.
In our standard design-build contract, we found ways to share risk with the contractor. The second thing is we are installing the new signaling systems and removing the conventional signal system.
Since the Summer of Hell in 2017 snapped everyone's attention to the underground infrastructure issues, the MTA has emphasized its focus on upgrading subway signals from Depression-era fixed-block signals.
The contract to upgrade signals on the G train was the first signal upgrade contract the MTA ever gave out in a design-build fashion.
Between the 2020-2024 capital plan and the 2025-2029 capital plan, the MTA has committed to installing the advanced signals on 200 miles of tracks.
