Short answer: Austrian private operator Westbahn has filed plans with the regulator Schienen-Control to launch three new long-distance routes: Vienna–Budapest Kelenföld, Vienna Central Station–Lienz via the new Koralm Railway, and Vienna Westbahnhof–Villach via the Tauern line. The filings, reported on 17 July 2026, are an open-access challenge to state operators ÖBB in Austria and MÁV in Hungary on Central Europe's busiest east–west corridor. No launch date has been set and the rollout is held back by a continental shortage of railcars.
For anyone who has paid full fare on the Vienna–Budapest railjet, this is the most interesting piece of competition news in years. Westbahn — the red private operator that broke ÖBB's monopoly on the Salzburg–Vienna corridor in 2011 — now wants to do the same on the Vienna–Budapest axis, the most trafficked international rail line in the region.
What Westbahn has actually filed
The filings were first reported by Vindobona.org on 17 July 2026 and cover three distinct long-distance services, all of them formal notifications to the Austrian regulator Schienen-Control under the EU's Fourth Railway Package:
- Vienna Central Station (Wien Hbf) ↔ Budapest Kelenföld — a new cross-border service into Hungary, terminating at Kelenföld in southern Buda rather than the central Budapest Keleti. This is the service that would directly challenge the ÖBB/MÁV railjet that has held the corridor alone for decades.
- Vienna Hbf ↔ Lienz (East Tyrol) — running via the brand-new Koralm Railway, Klagenfurt, Villach and Spittal-Millstättersee. This finally brings East Tyrol into Westbahn's network after years on the ÖBB-only branch line.
- Vienna Westbahnhof ↔ Villach — a parallel routing via Salzburg and the historic Tauern Railway, opening a second axis to the south.
A smaller idea also floats: extensions in the Salzburg region towards Saalfelden, feeding the Pinzgau local lines. None of the filings include a launch date or timetable yet — at this stage, Westbahn is reserving paths and broadcasting its strategic intent.
Why this matters for the Vienna–Budapest corridor
The Vienna–Budapest line is the busiest cross-border rail corridor in Central Europe. Today a single operator pairing — ÖBB railjet running Austrian rolling stock and MÁV-Start providing the Hungarian leg — operates most direct services in about 2 hours 40 minutes, with around 12–14 daily round-trips. Fares start at roughly €29 for a Sparschiene ticket bought weeks in advance and rise to well over €80 for a walk-up fare.
Westbahn's entry would change the maths on three fronts:
- Price pressure — Westbahn's brand is built on undercutting ÖBB on fares. A Vienna–Budapest one-way has historically started at around €19 on Westbahn pricing patterns, against €29 for railjet Sparschiene.
- Frequency — open-access competition is the only realistic way to grow capacity on the corridor, since ÖBB and MÁV have been slow to add trains post-Covid.
- Connectivity — by terminating at Kelenföld rather than Keleti, Westbahn would integrate the line with Budapest's M4 metro and several tram lines, giving direct access to southern Buda without a transfer across the Danube.
For Hungarian travellers, an open-access competitor would also make westbound trips cheaper: today, anyone heading from Budapest to Salzburg or Innsbruck has to either change in Vienna or pay a premium through-ticket on railjet.
East Tyrol and Carinthia finally get competition
The two southern filings are equally significant for domestic Austrian travellers. East Tyrol — the Lienz region — is one of the last corners of Austria still served only by ÖBB's regional trains over a single mountain line, with journey times to Vienna of around five and a half hours. The arrival of the Koralm Railway in December 2025 shortened Vienna–Klagenfurt to roughly three hours, and the Westbahn filing would extend that benefit east into the Lienz valley.
The Vienna Westbahnhof–Villach service via Salzburg and the Tauern Railway adds a second axis, important for ski traffic heading to resorts in Carinthia and Salzburger Land in winter. Today those journeys often involve a change at Schwarzach-St. Veit; a direct Westbahn service would mirror the way the operator already runs five direct daily round-trips on its core Vienna–Innsbruck corridor.
Why the trains will not start tomorrow
For all the excitement, Westbahn is being deliberately cautious about dates. The reason is not regulatory resistance — Schienen-Control is on record as favouring more open-access traffic — but rolling stock. The company is one of several operators caught in a Europe-wide shortage of railcars and multiple-unit trains, with major manufacturers such as Siemens, Stadler and Talgo all running months to years behind their delivery schedules.
Westbahn's existing fleet of red-and-silver Stadler FLIRT trainsets covers the Salzburg–Innsbruck–Vorarlberg core. To add Budapest, Lienz and Villach services without thinning out existing frequencies, the company needs additional trainsets that are simply not available off the shelf.
A Westbahn spokesperson, quoted by Vindobona, confirmed the "clear strategic goal" of establishing the new connections but did not commit to a launch date. The company is on record that the new routes "will not begin at the December 2026 schedule change", and is more likely talking about a phased launch from late 2027 onwards, depending on deliveries.
What this means if you are planning a trip
Until Westbahn actually starts selling tickets, the practical picture for travellers between Vienna and Budapest is unchanged. The fastest Vienna–Budapest journey is still the ÖBB railjet, at around 2 h 40 from Wien Hbf to Budapest Keleti, with MÁV EuroCity services as a cheaper fallback.
For now, the best way to keep an eye on Westbahn's plans is to:
- Watch the Schienen-Control public register for any updated timetables or path allocations.
- Compare today's railjet prices against FlixBus, RegioJet and shared taxis on the same corridor — a search on Gopaxo shows all of them side by side, which is a good way to spot when Westbahn's pricing eventually lands.
- For the southern corridors (Lienz, Villach, Klagenfurt), start using the new Koralm Railway services now via ÖBB — the journey-time improvements are real and independent of any Westbahn launch.

In short
- Westbahn has filed three new long-distance routes with the Austrian regulator Schienen-Control: Vienna–Budapest Kelenföld, Vienna Hbf–Lienz via the Koralm Railway, and Vienna Westbahnhof–Villach via the Tauern line.
- The filings are an open-access challenge to ÖBB in Austria and MÁV in Hungary on Central Europe's busiest east–west corridor.
- No launch date has been set: the rollout is blocked by a Europe-wide shortage of railcars, and Westbahn has confirmed the new trains will not start at the December 2026 schedule change.
- A launch is more realistic from late 2027 onwards, depending on rolling-stock deliveries from Stadler, Siemens or other manufacturers.
- Travellers between Vienna and Budapest will not see a change in 2026, but the long-term outlook is the most competitive the corridor has been in decades.
Frequently asked questions
When will Westbahn start running Vienna–Budapest trains?
There is no published launch date. Westbahn filed the route with the Austrian regulator in mid-July 2026, but the company has confirmed the service will not start at the December 2026 timetable change. A launch is more likely from late 2027 onwards, once additional rolling stock is delivered.
How will Westbahn's Vienna–Budapest prices compare to ÖBB railjet?
Westbahn has not published fares. On its existing Austrian routes, the operator typically prices its Sparschiene (Saver) tickets from around €19 one-way, undercutting ÖBB's €29 floor on the same corridors. The Vienna–Budapest railjet today costs €29–€80+ depending on how far ahead you book.
Where will Westbahn stop in Budapest?
The current filing lists Budapest Kelenföld as the Hungarian terminus, not the central Keleti station. Kelenföld is in southern Buda and is connected to the M4 metro line, which links to Keleti in around 10 minutes. This is similar to how the operator targets the second-city terminus on its Austrian routes.
Will the new Westbahn services also serve Klagenfurt and Villach?
Yes. The Vienna–Lienz service is routed via the Koralm Railway with stops at Klagenfurt, Villach and Spittal-Millstättersee, taking advantage of the new high-speed line that opened in December 2025. The parallel Vienna Westbahnhof–Villach service would run via Salzburg and the Tauern Railway.
Is this certain to happen?
It is a formal filing, not a launch announcement. Schienen-Control, the Austrian regulator, still needs to allocate paths, and Westbahn still needs the rolling stock. The filings are a strong signal of intent and they make the service substantially more likely than not, but the date remains provisional.
Austrian and Hungarian travellers should not expect new trains on the Vienna–Budapest axis this year, but the next 18 months are about to get a lot more interesting.
