Streckensperre/ CAT by bus

City Airport Train is temporarily replaced by premium buses and increases frequency to every 12 minutes*

CAT by bus

From September 7, 2026, through October 31, 2027, the City Airport Train will operate for 14 months using comfortable premium buses to ensure that transfers between Wien Mitte and the airport remain as convenient and fast as usual during the main line closure.

During this period, a section of the route between Wien Mitte and Rennweg will be closed to all rail traffic due to renovation work. CAT is even offering a special service for its passengers: the frequency of transfers will be increased, with up to five buses running every 12* minutes in each direction per hour. The high-quality Setra coaches are provided by Blaguss Reisen GmbH.

Holders of the Wiener Linien annual pass, the ÖBB Vorteilscard, the KlimaTicket, a student ID or pupils can use the CAT for 7 euros each way; children 15 and under ride for free. Unfortunately, due to logistical reasons, the CAT City Check-In service cannot be offered during the suspension of regular service.

From Wien Mitte/Landstraße (city centre) Marxergasse 1b (direct access through the CAT foyer): first bus 05:30 & last bus 23:15

From Vienna Airport Terminal 3/bus bay 0: first bus 06:10 & last bus 23:37

*7 a.m.-7 p.m., otherwise every 15 minutes

New trains in November 2027

From November 2027, the City Airport Train (CAT) will set new standards in airport transport: new five-carriage double-decker KISS trains from Stadler will be deployed on the route between Vienna Airport and Vienna city centre. The KISS200 model has been specially designed for high passenger volumes. Its modern and aerodynamic design, spacious interior and high level of innovation make the train ideal for busy express services.
