Romania (Romanian: România, Bulgarian: Румъния, Rumŭniya) is an international passenger train running daily from Bucharest, Romania to Sofia, Bulgaria. During summer months, the train operates together with the Bosphorus Express from Bucharest to Gorna Oryahovica, where the latter heads southeast toward Istanbul, Turkey.[1] Romania is operated by two national railway operators: Căile Ferate Române and the Bulgarian State Railways.
