Originally, all EuroCity trains carried names, and many still do, continuing the practice started with luxury trains of the late 19th and early 20th centuries. The names are printed on brochures showing the times of arrival and departure at every stop and details of the journey; these are placed on the seats by the train staff. A few trains have used the names of the earlier Trans Europ Express or InterCity trains that they replaced on the same route, for example "Iris" for Brussels to Zürich. The names were mostly related to the cities and region the trains served and chosen from historical or mythological figures, geographical and botanical names or regional products.
