Tram systems in Innsbruck
Innsbruck is located in the Inn Valley, where the River Inn passes between the high mountains of the Tyrolean Alps. It is the capital and largest city of the Austrian state of Tyrol and the fifth-most populous city in Austria.
The city developed as an important crossing point on routes through the Alps and later became a residence of the Habsburgs. Its historic centre includes the Golden Roof and the Imperial Palace, while Innsbruck is also a university city, an important tourist destination and an internationally known centre for winter sports. It hosted the Winter Olympic Games in 1964 and 1976 and the Winter Youth Olympic Games in 2012.
Innsbruck Hauptbahnhof is the city's principal railway station and an important junction for trains along the Inn Valley and across the Alps. It is served by Austrian and international long-distance trains, regional services and the S-Bahn Tirol network, with routes continuing towards the Brenner Pass and Italy, the Arlberg and other parts of Tyrol.
Innsbruck Airport lies to the west of the city and is connected with the centre by bus. Most urban public transport is operated by Innsbrucker Verkehrsbetriebe und Stubaitalbahn (IVB), whose network includes trams, regional light rail services and buses. Services are integrated into the Verkehrsverbund Tirol (VVT) fare system, while the Hungerburgbahn funicular links the city with Hungerburg on the lower slopes of the Nordkette.
Innsbruck has a metre-gauge tram network operated by IVB. Urban lines 1, 2 and 3 serve Innsbruck itself, while line 5 forms an east–west regional route between Technik West and Rum Bahnhof. Line 6 climbs from the city to Igls, and the Stubaitalbahn, identified as STB, continues through the western uplands and the Stubai Valley to Fulpmes. The two regional routes share tracks with the urban tram network within Innsbruck.
Innsbruck's first tramway was the metre-gauge Localbahn Innsbruck–Hall in Tirol, which opened in 1891. Steam trains ran from Bergisel in Wilten through Innsbruck and along the Inn Valley to Hall in Tirol. A second steam-operated local railway, the Innsbrucker Mittelgebirgsbahn between Bergisel and Igls, followed in 1900.
The Stubaitalbahn opened between Innsbruck and Fulpmes in 1904. It was electrically operated from the beginning, using an alternating-current system that was unusual for a local railway at the time. Innsbruck's first electric urban tram line opened on 15 July 1905, and the original city network of lines 1, 2 and 3 was developed between 1905 and 1911.
The railway to Hall was electrified in 1909 and 1910 and subsequently operated as tram line 4. The Mittelgebirgsbahn to Igls was electrified in 1936 and became line 6, bringing both of the older steam railways into the electric tram system.
The original line 2 ceased operating in 1936 as parts of the urban network were reorganised. Innsbrucker Verkehrsbetriebe AG was established in 1941 and took responsibility for the city's tramways and other public transport services.
The most significant contraction came on 8 June 1974, when line 4 between Innsbruck and Hall in Tirol was closed and replaced by buses. Complete abandonment of the remaining tram network was considered in 1975, but the proposals encountered public opposition and the system was retained.
A new tram depot was constructed in connection with the 1976 Winter Olympic Games. Second-hand articulated trams were subsequently acquired from Hagen and Bielefeld in Germany, allowing the ageing vehicle fleet to be renewed without the cost of purchasing an entirely new fleet.
The Stubaitalbahn retained its original alternating-current electrical system until 1983, when it was converted to the direct-current supply used by the Innsbruck tram network. This allowed its trains to leave the former Stubaitalbahnhof and continue over urban tram tracks to Innsbruck Hauptbahnhof.
Line 6 to Igls was also progressively integrated with the city network, and its older rolling stock was replaced during the 1980s. Although closure was considered on several occasions, the scenic route survived and continues to operate as part of the IVB system.
In 1997, Innsbrucker Verkehrsbetriebe AG and Stubaitalbahn AG were merged. The combined undertaking subsequently became Innsbrucker Verkehrsbetriebe und Stubaitalbahn GmbH, retaining responsibility for both the urban tramways and the Stubaitalbahn.
Innsbruck later adopted a policy of modernising and expanding its tramways, while the city's trolleybus network was withdrawn. Tracks, stops and depot facilities were rebuilt for wider vehicles and level boarding, and 32 Bombardier Flexity Outlook low-floor trams entered service between 2007 and 2009.
Line 3 was extended within Amras in May 2012. A new route through Anichstraße, Klinik and Höttinger Au followed in December 2012, forming the first part of the regional tram corridor towards the west. The tracks reached Technik, Technik West and Peerhofsiedlung in December 2017, while construction of the corresponding eastern sections continued during 2018.
New routes through Pradl, Reichenau and the Olympisches Dorf opened in January 2019, introducing the present lines 2 and 5. Twenty additional Flexity trams entered service between 2018 and 2020 to support the enlarged network. The eastern regional route was completed in March 2023, when line 5 was extended to the new public transport interchange at Rum Bahnhof.
The next planned expansion of Innsbruck's tram network is the westward extension of line 5 from Technik West to Kranebitten. This forms the first stage of the remaining section of the Regionalbahn between Innsbruck and Völs.
The project includes a new crossing of the River Inn and associated changes to roads and cycle routes. The section between Technik West and Kranebitten is planned as a double-track railway, while the proposed bridge over the B171 will also accommodate pedestrians and cyclists.
Detailed planning and negotiations over the land required for the project continued during 2025. Submission of the railway approval application is planned for autumn 2026, with the remaining road and environmental procedures expected to follow in early 2027. Preparatory work could begin during the second half of 2027, followed by the principal construction work in 2028.
Completion of the extension to Kranebitten is currently planned for the middle of 2030. Further information is available in the Province of Tyrol's 2025 transport report.
A second stage will continue line 5 from Kranebitten to Völs railway station. The completed route will create an east–west regional tram service between Rum and Völs through central Innsbruck, with connections to the mainline railway network at both ends.
Three new bridges are required along the complete extension from Technik West to Völs, carrying the tramway across the River Inn, the A12 motorway and the B171. The route will also serve the CYTA shopping centre before reaching its terminus at Völs station.
The extension is intended to allow passengers travelling from western Tyrol to change at Völs for destinations in western Innsbruck, rather than continuing to Innsbruck Hauptbahnhof and travelling back across the city. Political commitments for the project's funding are in place, with the cost to be shared equally by the Austrian federal government and the Province of Tyrol.
The original intention was to complete the entire extension in 2030. The current programme instead envisages opening the section to Kranebitten in 2030 and completing the railway to Völs in 2032. Further information is available from ORF Tirol.
ÖBB is undertaking a separate modernisation of Völs railway station in preparation for its future role as the western terminus of line 5. The project includes accessible station facilities, reconstruction of the station forecourt and the creation of a new public transport interchange.
The station work is planned to take place between 2026 and 2029. ÖBB will also construct a retaining wall between the mainline railway and the future tram alignment from 2027, providing infrastructure required before the Regionalbahn can reach the station.
Completion of the Regionalbahn between Rum and Völs is presently the principal expansion project for the Innsbruck tram network. Other possible extensions and new urban tram corridors have been discussed at different stages of the city's transport planning, but none currently has the committed funding, approval programme or opening timetable of the Völs project.
The opening dates for both stages remain dependent upon completion of the approval procedures, land acquisition and construction of the new bridges. The dates of 2030 for Kranebitten and 2032 for Völs should therefore be regarded as current planning targets rather than confirmed opening dates.
