Notes for Appendix 2:
FABN: This operator became Metrocampania NordEst from 2005 March 21.
UR: The United Nations Interim Administration Mission in Kosovo (UNMIK) operated the railway system in Kosovo during 1999-2008. During this time, Kosovo was a part of Serbia under United Nations administration. The railway system was organized as Hekurudha e Kosovës (HK) // Косовоске Железнице (КЖ) / Kosovske Železnice (KŽ) // “Kosovo Railway Enterprise”. Trains were operated by UNMIK Railways. Following the declaration of independence from Serbia by the Kosovo government on 2008 February 17, the previous arrangment was superseded by HK (q.v., above).
 
UR: Railways in Kosovo, a part of Serbia under United Nations administration, were organized as HK-KŽ (Hekurudha e Kosovës - Kosovske Železnice; “Kosovo Railway Enterprise”). Trains are operated by UR. See HK.
 
ŽS: Železnice Srbije (ŽS) is sometimes referred to as ŽTP Beograd (Železničko transportno preduzeće "Beograd"). This was the name for the Beograd division of Jugoslovenske Železnice (JŽ) prior to the breakup of Yugoslavia.
