What does "End electric field territory" denote in train operations?

The phrase "End electric field territory" in train operations specifically indicates the termination of electric track power. This is an important aspect of rail operations, as electric trains rely on a supply of electric power to function effectively. When trains reach this boundary, it indicates that the system transitions from electric-powered tracks to either non-electric (such as diesel) operations or to a station where the power supply changes.

This terminology is crucial for train crews to understand the limits of electric service. Entering an area where electric power is no longer available requires careful consideration of the operational protocols, including possible changes in the type of power used for locomotion or managing trains that rely on electric propulsion. Trains need to be adequately prepared before reaching this boundary, as it affects their speed, scheduling, and safety operations.

The other options, while related to train operations, do not accurately reflect the specific meaning of "End electric field territory." Understanding this term is vital for ensuring smooth transitions between different types of train operations.
