WIENER LINIEN GMBH &CO KG

Their core work

Wiener Linien is Vienna's public transport operator, running the city's metro, tram, and bus network — one of Europe's largest urban transit systems. In H2020 projects, they serve as a real-world testing ground and end-user for rail infrastructure innovations, smart mobility solutions, and automated transport systems. Their value lies in providing operational transit environments where research results can be validated at scale, from track maintenance technologies to shared autonomous mobility concepts.

What they specialise in

How they've shifted over time

From 2016 to 2019, Wiener Linien focused heavily on physical rail infrastructure — track maintenance, switches, crossings, bridges, and tunnels — through the Shift2Rail programme, alongside one smart city initiative. From 2019 onward, their participation pivoted toward the future of mobility: automated vehicles, human-machine interaction, MaaS (Mobility as a Service), and shared autonomous transport. This shift mirrors the broader European transit industry's move from maintaining legacy infrastructure to preparing for digitally integrated, automated urban mobility.

Wiener Linien is transitioning from a pure rail infrastructure focus toward becoming a multi-modal urban mobility operator integrating automation, MaaS, and connected transport systems.

How they like to work

Wiener Linien never leads consortia — they join as a participant or third party, contributing operational expertise and real-world validation environments rather than driving the research agenda. With 226 unique partners across 21 countries, they operate in large consortia typical of Shift2Rail and Innovation Action projects. Their repeated participation in sequential projects (IN2TRACK 1→2→3, IN2SMART 1→2) shows loyalty to established research partnerships, making them a reliable long-term collaborator.

Wiener Linien has collaborated with 226 unique partners across 21 countries, reflecting their involvement in large-scale EU transport research programmes. Their network spans the European rail and urban mobility research ecosystem, with particularly strong ties to the Shift2Rail community.

What sets them apart

Wiener Linien brings something most research partners cannot: a live, large-scale urban transit network serving over 2.6 million daily passenger trips where innovations can be tested in real operations. Their dual involvement in both rail infrastructure (Shift2Rail) and road-based automated mobility (DriveToTheFuture, SHOW) positions them uniquely at the intersection of traditional public transport and future multi-modal systems. For any consortium needing a major European transit operator as a demonstration or validation partner, they are an immediately credible choice.

Highlights from their portfolio

• DriveToTheFuture
  Their highest-funded project (EUR 57,000), marking a strategic shift into automated vehicle user behaviour and human-machine interaction research.
• IN2TRACK3
  The culmination of a three-project Shift2Rail series on rail infrastructure, demonstrating sustained long-term commitment to track and crossing innovation.
• SHOW
  Their most forward-looking project — shared autonomous mobility, MaaS, electric vehicles, and inclusive urban transport operating models.
