20.500.12556/DKUM-99927 Učinki nadgradnje železniškega odseka Maribor-Šentilj-d.m. Impacts of the upgrade of the Maribor-Šentilj-state border railway section Diplomsko delo obravnava učinke nadgradnje železniškega odseka Maribor–Šentilj–državna meja, ki predstavlja pomembno mednarodno povezavo slovenskega železniškega omrežja in del jedrnega omrežja TEN-T. Namen dela je analizirati stanje proge pred nadgradnjo, predstaviti izvedene infrastrukturne posege ter oceniti njihov vpliv na tehnične, prometne in varnostne parametre odseka. Analiza stanja pred nadgradnjo je pokazala, da so dotrajana infrastruktura, omejene hitrosti in zastareli sistemi vodenja prometa vplivali na zanesljivost in pretočnost proge. V okviru nadgradnje so bili izvedeni prenova tirne infrastrukture in postaj, izgradnja predora Pekel in viadukta Pesnica, odprava nivojskih križanj ter posodobitev signalnovarnostnih sistemov. Ključni objekti so bili hkrati načrtovani tako, da omogočajo prihodnjo umestitev dodatnega tira. Po nadgradnji so se izboljšali tehnični parametri, povečale dovoljene hitrosti, skrajšali vozni časi prav tako se je prepustna zmogljivost povečala. Kljub povečani zmogljivosti analiza prometa kaže visoko izkoriščenost enotirne proge, pri čemer je na analiziranem delovnem dnevu število vlakov preseglo njeno prepustno zmogljivost. Zaradi nadaljnje rasti prometa, predvsem potniškega, ostaja enotirnost glavna omejitev nadaljnjega razvoja odseka. Rezultati potrjujejo pozitivne učinke nadgradnje, hkrati pa kažejo na potrebo po čimprejšnji izgradnji drugega tira, ki bo omogočila bistveno povečanje zmogljivosti in stabilnejše odvijanje prometa. The diploma thesis examines the effects of the upgrade of the Maribor–Šentilj–state border railway section, which represents an important international connection within the Slovenian railway network and forms part of the TEN-T core network. The purpose of the thesis is to analyse the condition of the line before the upgrade, present the implemented infrastructure measures, and assess their impact on the technical, operational, and safety parameters of the section. The analysis of the pre-upgrade condition showed that worn infrastructure, limited speeds, and outdated traffic control systems affected the reliability and capacity of the line. The upgrade included the renewal of track infrastructure and stations, the construction of the Pekel tunnel and the Pesnica viaduct, the elimination of level crossings, and the modernisation of signalling systems. Key structures were also designed to allow for the future installation of an additional track. Following the upgrade, technical parameters improved, permitted speeds increased, travel times were reduced, and line capacity were increased. Despite the increased capacity, the traffic analysis indicates a high level of utilisation of the single-track line, with the number of trains on the analysed working day exceeding its available capacity. Due to the continued growth in traffic, particularly passenger services, the single-track configuration is staying the main constraint on the further development of the section. The results confirm the positive effects of the upgrade while also highlighting the need for the construction of a second track as soon as possible, which would enable a substantial increase in capacity and more stable railway operations. železniška infrastruktura nadgradnja proge prepustna zmogljivost prometna varnost dvotirnost railway infrastructure line upgrade line capacity traffic safety double‑tracking true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-31 08:28:19 2026-09-10 11:48:59 2026-09-11 03:08:02 0000-00-00 00:00:00 2026 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 VS_Predan_Spela_2026.pdf VS_Predan_Spela_2026.pdf 1 6F34059BED1A6427FF4257C5E5B735C2 ebabc7f6b0ab53768014fa75406b64720b35df01b0d782f803ca8530edcf7d79 23f1cfe1-a506-11f1-b1f1-00155d0001be https://dk.um.si/Dokument.php?lang=slv&id=210981 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
