What defines a Controlled Point in MTA operations?

A Controlled Point in MTA operations is defined as a station where signals are remotely controlled from the Operations Control Center. This centralized management allows operators to efficiently manage train movements, ensuring safety and optimal scheduling. The remote control of signals is crucial in coordinating traffic across the rail network, enabling the real-time adjustment of train routes and preventing conflicts that could lead to delays or accidents.

In contrast, the other options do not accurately represent what constitutes a Controlled Point: a remote station controlled by passengers would not have the same level of operational oversight; a meeting point for conductors does not involve signal management; and a designated rest area for crew members is not related to the control of train signals. Hence, the key role played by the Operations Control Center in managing signals at these locations underscores why the definition aligns with option B.
