What does a headway of 10 minutes indicate in train scheduling?

A headway of 10 minutes in train scheduling refers to the time interval between the departures of consecutive trains on the same route. This means that there is a consistent gap of 10 minutes before the next train leaves the station after the previous train has departed.

Understanding headways is crucial for managing train frequency, capacity, and ensuring that passengers have reliable access to services. A shorter headway typically indicates a more frequent service, which can enhance the overall efficiency of the transit system.

The other concepts, while related to train operations, do not accurately describe the term 'headway.' Specifically, it does not refer to arrival times, route completion times, or crew rest periods, making the correct answer focus specifically on the timing of departures.
