To what does the term "controlling train movements" refer?

The term "controlling train movements" refers to coordinating train operations and scheduling, which is essential for ensuring safety and efficiency within the rail network. This involves various tasks such as managing train traffic, scheduling departures and arrivals, and ensuring that trains operate smoothly without conflicts. Effective coordination helps prevent accidents, reduces delays, and optimizes the use of the rail infrastructure.

While determining speed limits, using radio communication for schedules, and tracking locations are important components of train operations, they are more specific aspects of the broader concept of controlling train movements. The overarching goal is to manage all aspects of train operations in a cohesive manner, which captures the essence of coordination.
