stations or from approximately 4,000 travel agencies including those outside Italy. It is common for people to buy tickets from the official website after looking up schedules. Since long-distance trains, unlike the regional trains, usually require a reservation, it is advantageous to buy tickets in advance. This also gives buyers access to a variety of discount schemes offered by Trenitalia. All "premium" long-distance trains generally share the same discount schemes, even though their fares may differ. Unlike mini fares, which existed before 2012 and required two days of notice, all tickets may be purchased at the last minute if they are still available. All large rail stations have staffed ticket windows and self-service ticket machines for this purpose. Such machines, which either say "Trenitalia" or "Rete Regionale" ("regional network"), differ in the types of payment accepted. Controversies Racism In early 2012, Trenitalia released a web advertisement to promote its change from two classes of train compartments into four classes. Passengers travelling by the fourth class were not permitted to use the on-board cafeteria or enter the carriages reserved for the other three classes. This change alone reportedly caused controversy, but more followed with the release of the accompanying web advertisement. The web advertisement showed only white people seated in the upper three classes, as well as a black family in the fourth. Italian online media observed this and branded the advertisement as "grotesque". Other complaints of racial discrimination followed in UK newspapers, social media and online. Trenitalia withdrew the web commercial and quickly substituted it following the allegations of racism. Since 13 January 2012 the cafeteria is accessible also for passengers of lower classes.
