Mar 11, 2025 · Communications-based train control (CBTC) drastically improves the reliability of subway service. Here are details about how it works, how it benefits customers, and where we're installing it.

Communications-based train control (CBTC) is a railway signaling system that uses telecommunications between the train and track equipment for traffic management and infrastructure control. CBTC allows a train's position to be known more accurately than with traditional signaling systems.

As part of the modernization of the New York City Subway, the Metropolitan Transportation Authority (MTA) plans to upgrade and automate much of the system with communications-based train control (CBTC) technology, which will automatically start and stop trains.

Jan 16, 2024 · To address the issues of fixed-block signaling, the MTA has announced signal modernization plans across some of the system’s oldest and busiest train lines. These projects will install new, more reliable technology, known asCBTC (communications-based train control).

Sep 17, 2019 · With two CBTC-equipped lines in service by the start of this year, the benefits of partial automation of the Subway were starting to be realised. But the ultimate objective of supplier-independent interoperability remained elusive, with Siemens having equipped one line and Thales the other.

Mar 6, 2025 · When this work is completed, 40% of the subway will be operated with CBTC. Where CBTC is completed, under construction, or planned. MTA. Candidate Corridors in the 2025-2029 Capital Plan. CBTC Corridors. Switch Embed. When fully implemented, improvements on 2025-2029 Capital Plan CBTC-enabled lines would save riders a combined 12,000 hours ...

Jul 21, 2015 · Continuous updates allow the subway system to recover quickly from delays and restore consistent wait times at subway stations. The installation of CBTC will keep the signaling system in a...

Mar 29, 2022 · The Metropolitan Transportation Authority wants to hire engineering consultants to design and plan so-called communication-based train control, or CBTC, on the next batch of subway lines,...

Sep 3, 2022 · The MTA plans to fix the issue by implementing CBTC or communications-based trains control to fix the aging signal system as part of a $508.3 million signal modernization project.

This report will explain what CBTC is and how it works. It will discuss the status of CBTC in New York City’s subway system, and make recommendations to implement it more quickly and efficiently. What is Communications-Based Train Control?
