In 2014, InterCity trains were replaced in their entirety by InterRegio trains, only to make an illegal comeback (train sets don't respect all the obligatory criteria for InterCity trains ironically signed by the same government a few months prior to their comeback) in 2022, with the new train timelist. Serbia Currently InterCity lines link the capital Belgrade to Novi Sad, Subotica and Prijepolje. There is new interCity service between Belgrade and Novi Sad called Soko witch uses Stadler KISS and speed up to 200km/h. Slovakia 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). In the past, there were also 3 other InterCity services: IC 400/407 Donau (Danube) between Bratislava and Vienna, IC 532/533 Rákoczi from Košice to Budapest and IC 536/537 Hornád from Košice to Pécs. On this train passengers could travel without a reservation or surcharge, since it is impossible to use them for domestic transport in Slovakia. All
