Romania Currently InterCity lines link the capital Bucharest to Brașov, Arad, Oradea, Cluj-Napoca, Târgu Mureș, Galați (all once daily), Suceava, Iași (twice daily), Piatra Neamț (once daily), Bacău (4x daily), Ploiești (6x daily), Craiova (twice daily) and Timișoara (once daily). There are also international trains branded as InterCity between the Hungarian capital, Budapest and some Transylvanian cities such as Cluj-Napoca, Târgu Mureș, Brașov, and others. These trains usually have specific names (Harghita, Ady Endre, etc.). In the case of IC service running partially or totally on electrified lines as well as international IC-s locomotive-hauled trains are used. For some trains running exclusively on unelectrified lines (mainly in northern Transilvania) Siemens Desiro DMU-s are preferred. These trainsets look similar to standard Desiro DMU-s used for regional trains but have a different interior design with more comfortable seating. All IC trains use 1st and 2nd class coaches with air conditioning, having automatic doors and a higher level of comfort than InterRegio trains. In order to compete with regional airlines, CFR Călători introduced special Business class coaches on the IC trains running between Oradea and Bucharest and Timișoara
