The connection

What runs on this corridor

ÖBB describes a direct Railjet connection from Vienna and Linz to Munich every two hours during the day. The route runs via Salzburg; exact stops, journey time and any disruption depend on the date.

A through connection avoids a scheduled interchange. It does not rule out disruption, replacement transport or a changed itinerary. Check the actual train before booking.

Train vs flight vs car

CO₂e per journey: one person or one car

Each mode uses its own activity distance: rail the route length, flying the great-circle distance between airports, driving the routed road distance. Ranges come from the published factor bands, not from measurement error.

Mode	Factor used	kg CO₂e	Range
Train	grid model, endpoint average × 0.09 kWh/pkm22 g/pkm × 445 km	9.8 kg	4.4–15.3 kg
Flight	128 g CO₂e/pkm, DESNZ 2026 short-haul with RF128 g/pkm × 356 km	46 kg	45–67 kg
Car (whole vehicle)	166 g CO₂e/vehicle-km, DESNZ 2026 average car166 g/veh-km × 404 km	67 kg	22–113 kg

36 kg CO₂e

Difference, rail vs flight

About 78% below the flight value in this model — per person, one way.

How this was calculated

Rail: the annual grid snapshot gives 110 g CO₂e/kWh for Austria and 381 g CO₂e/kWh for Germany. A cross-border leg averages its endpoint countries, so 246 g/kWh × 0.09 kWh per passenger-kilometre = 22 g CO₂e/pkm. Over 445 km of route that is 9.8 kg CO₂e per person. The range spans the two endpoint countries taken separately. Rounded scenario distance for the Railjet routing via St. Pölten, Linz and Salzburg, rounded to 5 km.
Flight: UK DESNZ 2026 short-haul average passenger with radiative forcing, 128 g CO₂e/pkm (range 126–189), over the 356 km great-circle distance between the airport pair = 46 kg CO₂e per person. Great-circle distance is an approximation between airport coordinates, not the flown track, and it excludes getting to and from the airport.
Car: UK DESNZ 2026 average car, 166 g CO₂e per vehicle-kilometre (range 55–280), over the 404 km routed road distance = 67 kg CO₂e per vehicle. That is the whole vehicle: shared between two or four people, the per-person figure drops accordingly.
Cross-check: the static catalogue factor for national rail (31 g CO₂e/pkm) would give 13.8 kg over the same route. The grid model can sit well below it on low-carbon electricity. Rail figures cover electric intercity operation — diesel sections, actual occupancy and upstream energy are not modelled.
All values are model calculations from published factors under Farleda methodology v1.1, not measurements, and describe one-way travel. Rail and flight are per person; the car row is per vehicle.

The record

What the signed record for this route looks like

When a plan for this corridor is saved in Farleda, the result is a Trip Carbon Passport: a canonical payload with distance, modes, rounded leg summaries, traveller count and declared methodology/comparison versions, signed by the server with HMAC-SHA256. Anyone can check any passport publicly, without an account. A valid result shows the payload has not changed since Farleda signed it — it does not prove the journey physically happened, and it is not an offset or a certificate.

Public access depends on the API release. The verification page explains the current access to the service.

Tickets and coverage

What is and is not covered

The KlimaTicket Ö covers the Austrian section within its applicable tariff area, including specified border stations and foreign sections. An onward ticket is required beyond the applicable tariff boundary.
The Deutschlandticket is not valid on long-distance trains, so it does not cover the Railjet or ICE on this corridor.

Ticket rules change. Check the operators’ conditions and the KlimaTicket validity map linked below.

Questions

Frequently asked about this corridor

How long does the train from Vienna to Munich take?

Exact journey times depend on the date and direction. Check the linked operator journey planner; the overview above describes the reviewed connection.

Is there a direct train from Vienna to Munich?

Yes. ÖBB Railjet and DB operate the corridor as a through service via Linz and Salzburg — no change of train is needed.

How much CO₂ does the train save compared with flying?

In our model calculation roughly 36 kg CO₂e per person one way: about 9.8 kg by rail against about 46 kg by air. Both are modelled ranges from published factors, not measurements.

Is the train faster than driving Vienna–Munich?

The rail run is about four hours; the 404 km road route is normally quoted at around four and a half hours of pure driving before breaks and traffic. Rail is competitive on time and clearly lower in our modelled emissions.

Does the KlimaTicket cover the trip to Munich?

Only in part. The KlimaTicket Ö is valid within its applicable tariff area, including specified border stations and foreign sections; the German section needs a separate ticket. The Deutschlandticket does not apply to long-distance trains.

How are the CO₂ figures on this page calculated?

Rail uses the Austrian and German grid snapshot averaged and multiplied by 0.09 kWh per passenger-kilometre; flying uses 128 g CO₂e/pkm (UK DESNZ 2026, with radiative forcing); the car row uses 166 g CO₂e per vehicle-kilometre. The footnote under the table shows every step.
