In Europe, railway companies assign trains to different categories or train types depending on their role, i.e. based on the used rolling stock, their speed (high-speed, higher-speed, conventional), distance of travel (long, medium, short), stopping frequency (Inter-city, limited express, express, limited-stop, regional, commuter) and other criteria. Train categories/types often have specific abbreviations (e.g. IC). In addition, different lines or individual trains may be numbered. The abbreviations (and numbers) are usually indicated in timetables, passenger information systems and sometimes also on the destination sign of the train. There is no common classification scheme throughout Europe; each country has its own, although categories of internationally operating trains are used across borders (e.g. EC).
A train type is not essentially a trademark name. However, there are trademark names that are also used as train types, such as the VogtlandExpress (VX) or the former CityNightLine (CNL) and Cisalpino (CIS).
