Where these numbers come from
Derived from service area No carrier record names this exact pair. The operators listed publish a service area covering both places at a distance their mode plausibly carries people, which is evidence that the corridor is served and not evidence of a specific service. Pages state which, because presenting the two as the same thing would be dishonest.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
