The CFR Calatori 641 363-2 seen between Oradea Est Triaj and Osorhei

The Oradea to Cluj railway's construction was a difficult process; in fact, all railways were problematicly conceived and arrived late in Transylvania despite the natural resources offered by the area. Construction began by a state decision but soon an English private company (Waring&Eckersley) took over the construction and the rights for later exploitation. As the private company drifted toards bankrupcy it was nationalized and all offered lines were finished by the State Railway of Hungary (MÁV).
