The location at the junction of the Mediterranean, the Alps, the Dinarides and the Pannonian Plain and the area being traversed by major rivers have been the reasons for the intersection of the main transport routes in Slovenia. Their course was established already in Antiquity. A particular geographic advantage in recent times has been the location of the intersection of the Pan-European transport corridors V (the fastest link between the North Adriatic, and Central and Eastern Europe) and X (linking Central Europe with the Balkans) in the country. This gives it a special position in the European social, economic and cultural integration and restructuring. Railways The existing Slovenian rails, which were mostly built in the 19th century, are out-of-date and can't compete with the motorway network. The maintenance and modernisation of the Slovenian railway network has been neglected due to the lack of financial assets, creating bottlenecks. Nevertheless, it has been gaining momentum with the completion of the motorway cross. The Slovenian Railways company operates of standard gauge tracks, as double track, and reaches all regions of the country. The network comprises main lines and regional lines. Electrification is provided by a 3 kV DC system, except at the junctions with railways of foreign countries, and covers . Due to the out-of-date infrastructure, the share of the railway freight transport has been in decline in Slovenia despite growing slightly in absolute terms. The railway passenger transport has been recovering after a large drop in the 1990s. The Pan-European railway corridors V and X, and several E-railways (E65, E67, E69, and E70) intersect in Slovenia. All international transit trains in Slovenia drive through the Ljubljana Railway Hub, and all international passenger trains stop there. As of 2018, first tenders should be invited for the upgrade of the Divača-Koper Railway. Roads With the share of over 80%, the road freight and passenger transport constitutes the largest part of transport in Slovenia. Personal cars are much more popular than public road passenger transport, which has significantly declined. Motorways and expressways, operated by the Motorway Company in the Republic of Slovenia, are the state roads of the highest category. On motorways and express ways, cars must have a toll sticker. Slovenia has a very high motorway density compared to the European Union average. The first highway in Slovenia, the A1 motorway connecting Vrhnika and Postojna, was opened in 1972, but the construction was really
