What does the acronym CBTC stand for in train operations?

The acronym CBTC stands for Computer-Based Train Control. This system represents an advancement in train operations that utilizes computer technology to manage and automate train movements, improving efficiency and safety. CBTC relies on real-time data and communication systems to closely monitor the location and speed of trains, allowing for more precise control and reducing the distance between trains, which can increase the overall capacity of the rail network. This technology is pivotal in modern railway systems, as it enhances operational flexibility and minimizes the risk of human error.

The other options do not accurately represent the current terminology and technology applied in the field of train operations. While they may include elements related to train control, they do not encompass the comprehensive, technology-driven approach that CBTC embodies. Understanding this distinction is crucial for recognizing the importance of modern signaling and control systems in ensuring safe and efficient train operations.
