NYCT: Communications-Based Train Control

Learn all about CBTC, the future of the New York City Subway. Installation of a new CBTC system allows NYC Transit to operate more trains per hour, thereby increasing passenger capacity; provide improved and more reliable service; and make more efficient use of its track and car fleet. The system is more flexible than the current block signals system because CBTC continuously updates train positions, distances and travel speeds, allowing for faster and more efficient operations.
