- Connects countries with inter-country, sometimes overnight, usually long distance trains.
- Like the EuroCity and EuroStar trains.
- In North America, there are three Amtrak routes between USA and Canada which are passenger=international: Adirondack, Cascades and Maple Leaf. With lengths of ~600 to 900 km, these are neither "long distance" nor overnight trains, though they are "inter-country" (customs and passport check within 100 miles of the border, etc.)
