Features: After crossing the Süd Autobahn (A2) the Koralmbahn branches off the existing Südbahn tracks.
Immediately after the junction a 3 km-long subsurface route will be erected which will also include a station serving Graz Airport.
This stretch was upgraded in order to meet High-speed rail and S-Bahn standards.
Specifically, level crossings were replaced by undercrossings and train stations were upgraded with some of them now serving as interchanges to other transport modes.
The railway is primarily built for intermodal freight transport but will also be used by passenger trains travelling at up to 250 km/h.The travel time from Klagenfurt to Graz will be reduced from three hours to 45 minutes. dating for par Christiansø Commissioning of the first new track section began in 2010 and construction is expected to be completed in 2022.The current railway layout makes it difficult for services to and from Vienna to simultaneously serve both Graz and Klagenfurt (the biggest cities in the Styria and Carinthia Länder respectively). Unless trains backtrack to Bruck an der Mur, the shortest railway route between the two cities runs via Maribor, Slovenia.As a result, ÖBB currently serves Graz and Klagenfurt with separate Railjet services.
Reemerging on the surface the tracks will then cross the Grazer Feld plain and subsequently follow the Pyhrn Autobahn (A9).South of the Container terminal Werndorf two junctions to the existing Southern Railway line will be built - the first to integrate the container terminal, the second (Weitendorf junction) will serve as a connection for local railway services.double-track, electrified, high-speed railway that is under construction, and which will connect the Austrian cities of Graz and Klagenfurt.Construction started in 2001, and the entire railway line is expected to be operational by 2023.The connection is possible via a three-hour train journey via Bruck an der Mur, though ÖBB currently runs Intercitybus services between Graz and Klagenfurt via Wolfsberg at a frequency of approximately two hours with a journey time of two hours. In combination with the projected 27 km-long Semmering Base Tunnel the Koralmbahn will remove bottlenecks in the Austrian freight and passenger railway infrastructure (namely the Semmering Pass and the Neumarkt Sattel).
