What is the term for the time interval between trains?

The term that describes the time interval between trains is "Headway." This concept is crucial in train operations as it determines how frequently trains arrive at a station and the overall efficiency of the service. Headway is typically measured in minutes and is essential for maintaining a reliable transit schedule.

Understanding headway helps train operators manage train traffic effectively and ensure that trains can safely operate without interference. A shorter headway indicates more frequent service, which improves accessibility for passengers, while a longer headway may indicate a less frequent service that can lead to longer wait times for passengers.

Other terms such as "Time Gap," "Frequency," and "Spacing" are related but do not specifically denote the time aspect between trains. While frequency refers to how often trains run per unit of time, and spacing typically addresses the distance between trains, it is headway that directly defines the time interval that is critical for scheduling and operational efficiency.
