The Metropolitan Transportation Authority recently announced that the MTA Board approved the first of three contract awards that will extend signal modernization along the Queens Boulevard Line east of Kew Gardens-Union Turnpike station with Communication-Based Train Control (CBTC).
The upgrade of the signal system to CBTC will allow trains to safely run at a greater speed and at closer distances, providing more efficient and reliable service on the E and F lines.
The Queens Boulevard Line East Project will modernize four interlockings, at Jamaica-179 St, 169th St, Parsons Blvd, and Briarwood. The interlocking at Union Turnpike, which currently has CBTC functionality only toward the west, will be fully equipped with CBTC functionality.
“CBTC is key to improving subway service because it allows dispatchers to know real-time positions of trains in a much more precise way, which allows the MTA to schedule more trains and operate them more reliably,” said MTA Interim NYC Transit President Craig Cipriano. “This expansion of CBTC will improve train service on this busy corridor and allow us to provide more accurate real-time arrival information for our customers.”
This first contract award is for the design, delivery and testing of the CBTC equipment, and is valued at $62.6 million over 55 months. The second award will be for the installation of the CBTC equipment. The third contract will be for the installation of the Data Communication System. CBTC uses radio communications to constantly connect the MTA’s trains and signal system, with service managed dynamically by a computer system in New York City Transit’s Rail Control Center.
Trains operate with CBTC on the L and 7 lines, which were brought online in 1996 and 2019 respectively. The MTA is currently installing CBTC on two-line segment expected to go into service next year: the Queens Boulevard Line between Kew Gardens-Union Turnpike and 50 St in Manhattan, and the F line between Church Av and West 8 St-NY Aquarium. The MTA is also installing CBTC on the A C E line between 59 St-Columbus Circle and Jay St-MetroTech, which is expected for completion in 2025. Future line segments to receive CBTC are the G line between Hoyt-Schermerhorn and Court Square, the A C line between High St and Euclid Av, and the F line between Jay St-MetroTech and Broadway-Lafayette St.
Some Benefits of CBTC
More efficient service. Because it allows dispatchers to know exactly where trains are on the track, CBTC enables the MTA to run trains closer together. The 7 and L lines, which both use CBTC, are the best-performing lines on the New York City Subway. On-time performance on our existing CBTC lines is consistently near or above 90 percent.
Lower operating costs. Accelerating trains is expensive, so intelligently controlling the speed of trains saves the MTA money. Maintenance is also cheaper with CBTC because it isn’t as hardware intensive, and software can be upgraded as technology improves.
Faster service. Running trains closer together helps the MTA increase capacity on a line. Trains can also travel at higher speeds without compromising safety.
More reliable service. Signal problems are among the leading causes of delays in subway service. Upgrading the technology means fewer issues, and when delays happen, crews will be able to get service back on track more quickly. The existing signal system east of Kew Gardens is more than 85 years old, one of the oldest segments remaining in the system.
