Competitive framework for an integral interval timetable in long-distance passenger rail services
The decision to centrally organize long-distance passenger rail services in the form of an integral interval timetable (IIT) in the same way as short-distance passenger rail services offers the opportunity to induce competition in the market for long-distance passenger rail services.
