Travelling on an InterRegio train
The term InterRegio refers to a type of European trains which links regions within a country. Usually abbreviated as IR, they stand between a Regional Express and an Intercity when it comes to speed and service. As a rule of thumb, InterRegio services are more upmarket in Switzerland and more basic in Belgium, Hungary, Portugal and Poland.
In Poland, InterRegio trains are used on long-distance routes. They are, however, not as fast as Intercity services. In Germany there are a limited number of InterRegio Express (IRE) trains, which share routes with Regional Express services.
InterRegio trains often consist of older carriages – except in Switzerland, where high-quality trains are regularly deployed on IR routes. Yet even older IR carriages are generally comfortable and have good luggage space. Seat reservation is usually not possible. Air-conditioning is not standard. In Poland and Hungary IR trains are Standard Class only.
Seating and sleeping on InterRegio
Standard Class seating on InterRegio services can be in open-plan carriages or in six-seat compartments. Some trains, particularly in Switzerland or on IRE routes in Germany, have double-deck carriages. Luggage space is available at the end of each carriage or in racks above seats.
Food and drink on InterRegio
On some Swiss InterRegio trains, a trolley service offers snacks and hot and cold drinks at your seat, including freshly brewed Lavazza coffee. Examples are the trains between Zurich and Luzern and Luzern and Geneva. A trolley service also exists on a small number of InterRegio Express (IRE) services in Germany, for example on the IRE train between Berlin and Hamburg.
