In the Slovak Republic, InterCity trains run between the capital Bratislava and Košice (some IC trains continued from Bratislava to Vienna). In the past, the names of some of these trains used to be sold for commercial use (IC Šariš named by beer producer, IC Zelmer named by an electronic devices producer, IC Slovenka named by a magazine, IC Mora, IC Gorenje, both named after kitchen appliances producers). In 2012, no IC train had commercial name. All IC trains are named by natural monuments (IC Tatran, IC Kriváň, IC Gerlach, IC Rysy, IC Chopok, IC Ďumbier). All IC trains are subject to compulsory reservation to make comfort as high as possible. The seat reservation is included in the ticket price. The price varies, depending on the day of travel, and the time of reservation (the sooner you buy a ticket, the lower the price).
