An innovative regional transport project, the S-Bahn Carinthia light rail system offers quick and convenient connections to Carinthians traveling along the S-1, S-2, and S-3 lines. Since the project's inception over two years ago, annual carbon emissions have been reduced by about 10,000 tons. To date, most of the S-Bahn passengers in Carinthia's have been commuters. In times of astronomically high gas prices, the S-Bahn light rail has emerged as an attractive alternative to individual transport.

The S-1 line runs from Spittal/Drau to Villach, then to Klagenfurt, and terminates in Friesach. It offers 700 designated park & ride spots. An hourly service, the S-2 line connects St. Veit with Feldkirchen, Villach, Faaker See, and Rosenbach. 100 park & ride spots are available. The S-3 line runs from Feistritz/Rosental to Klagenfurt, Kühnsdorf, and Bleiburg. During morning peak times, it runs every 30 minutes (between Feistritz and Klagenfurt, and between Kühnsdorf and Klagenfurt) -- at all other times, the interval is one hour. More than 250 park & ride spots are available along the S-3 line.

From July 2 to September 11, there will be additional weekend "S-Bahn Nightline" trains, which are scheduled to run between Spittal and Villach, and between Klagenfurt and St. Veit.

On February 14 2012, the city of Klagenfurt introduced an innovative, environmentally friendly bus system. Since then, the new transport system has helped lower fine particulate matter pollution levels, has reduced the city's traffic volume, and has brought a novel transport experience to the people of Klagenfurt. With the introduction of an optimized route design and separate schedules for daytime and nighttime traffic, Klagenfurt's municipal works (STW) have set new standards in public transport.

Thanks to a number of smart modifications in route design, bus travelers are no longer forced to pass through the Heiligengeistplatz connection hub. In addition, a reorganization of the city's park & ride facilities is in the works. In the future, park & ride locations will be fully integrated within the STW network, thus eliminating the need for designated buses. Park & ride customers will only have to pay the bus fare -- parking will continue to be free.

Another improvement in the STW network is the new schedule: since February 14, all buses have been running in 30-minute intervals. During the busy weekday morning hours (6:30 - 8:30), they even run every 15 minutes. As many sections are served by more than one line, approaching the city center bus intervals get shorter and shorter. At nighttime and on weekends, buses run once per hour. On Friday and Saturday nights, they run as late as 1 a.m. Thanks to the new and improved STW network, Klagenfurt now features direct and environmentally friendly east-west and north-south bus connections.
