Ukrainian Railways is the state railway network operator in Ukraine, a monopoly that controls the railroad transportation in the country with a combined total length of track of over 23,000 km. http://uz.gov.ua/en/
Railway services in the NGCA are very limited. However, three railway links between GCA and NGCA are operational (green and yellow in below map) and can technically be used. The use of railway to transport humanitarian cargo has legally become possible since 28 September 2015.
