What does the term "intermediate" refer to in Regional Rail Trips?

The term "intermediate" in the context of Regional Rail Trips specifically refers to a stop that occurs between the starting point (origin) and the final destination. This implies that passengers may board or alight at various points along the journey, which are not the endpoints. The concept of an intermediate stop is crucial for understanding how routes are structured, as it allows for flexibility and accessibility in service, enabling passengers to access various locations without needing to travel to the primary terminals.

In contrast, options like a trip involving multiple connections, a limited stop service, or a round trip transfer do not accurately capture the meaning of "intermediate." These terms refer to different service aspects or requirements that don't necessarily pertain to a stop being placed between the origin and destination of a specific route.
