How do 'phase gaps' generally affect train operations?

Phase gaps primarily relate to power supply issues within the context of train operations. In rail systems, particularly those using electric trains, phase gaps refer to interruptions in the electrical supply that can occur when the train transitions between different power sources or sections of the track. These gaps can affect the continuity of power, leading to potential disruptions in train operations.

When there are phase gaps, trains may experience a loss of power or inconsistent electrical supply, impacting their ability to operate smoothly and efficiently. This can result in slower acceleration, delays, or even stalling of trains if not managed properly. Therefore, understanding and managing phase gaps is crucial for ensuring a reliable power supply that directly affects train performance and safety.

The other options touch on different areas of train operations. For example, measuring distance is more associated with track measurements and signaling rather than electrical supply. Scheduling of train arrivals pertains to timetable management and operational logistics, while maintenance areas focus on physical condition assessments of the tracks and equipment rather than electrical phase considerations.
