Austrian Federal Railways (ÖBB) is launching its first double-decker railjet units on long-distance routes this December, deploying 14 six-car Stadler Rail (SWX: SRAIL) KISS trainsets to combat severe overcrowding on the primary Vienna-to-Salzburg corridor. The 160-meter sets increase seating capacity by 20% to 486 seats while operating at speeds up to 200 km/h.
The Bottom Line
- Capacity Expansion: Six-car double-decker configurations deliver 486 seats per unit, expanding passenger volume by 20% on core Austrian routes.
- Fleet Integration: The December rollout follows rolling stock orders placed in 2023 with manufacturer Stadler Rail, alongside complementary regional CityJet deployments and secondhand acquisitions originally operated by Deutsche Bahn (ETR: DB) subsidiaries.
- Onboard Logistics: Each trainset integrates 8 restrooms, automated beverage and dining kiosks, dedicated spaces for 10 bicycles, and specific accessibility infrastructure for wheelchair users.
Addressing Mainline Bottlenecks Through Rolling Stock Innovation
As passenger volumes across Central European rail corridors rebound past pre-pandemic baselines, major operators face acute capacity constraints. ÖBB is directly targeting this friction on its high-demand western axis connecting Vienna and Salzburg. Traditional single-level railjet equipment has faced mounting utilization pressure, prompting management to pivot toward high-density multi-level architecture.
Here is the math: replacing single-level configurations with six-car Stadler Rail KISS units lifts per-train passenger capacity to 486 seats. That represents a precise 20% expansion in available inventory without requiring track infrastructure overhauls or increased slot allocations on heavily congested rail networks. The units maintain a commercial top speed of 200 km/h, ensuring transit times remain competitive against highway transport.
Fleet Consolidation and the Stadler Ecosystem
The introduction of these long-distance double-deckers follows a broader fleet modernization strategy executed by ÖBB. The state-owned carrier originally contracted Stadler Rail for these dálková (long-distance) units in 2023. Ahead of the official December timetable change, ÖBB showcased testing footage of the uncrewed trainsets, building toward a formal public premiere at the Innotrans trade fair in Berlin.
But the balance sheet tells a wider story of asset optimization across Austrian rail infrastructure. Stadler already supplies single- and multi-level KISS variants for regional operations under the CityJet brand. Furthermore, ÖBB expanded its capacity pool by purchasing older-generation KISS equipment previously operated by Deutsche Bahn via Westbahn, which entered commercial service this year on InterCity (IC) routes running from Salzburg to Villach. Simultaneously, double-decker cars are entering service on the scenic Tauern Railway through the Alps, lifting comfort and sightseeing views.
Onboard Architecture and Passenger Amenities
Operating high-density long-distance corridors requires balancing passenger count with onboard ergonomics. The new 160-meter-long trainsets address traveler friction points by integrating eight onboard restrooms across the multi-level cars. Food and beverage access relies on automated vending and dining kiosks rather than traditional staffed restaurant cars, lowering operating overhead for the carrier.
For multimodal commuters, the units feature dedicated storage bays capable of securing 10 bicycles per trainset—a critical operational requirement for tourist-heavy Alpine transit. Accessibility compliance is maintained via specialized boarding zones and dedicated interior spaces configured for wheelchair users, aligning with European Union rail transport mandates.
