The history of PostBus
We’re proud to keep Switzerland in motion.

  • 1906

    PostBus takes you on a journey through time.

    The first scheduled automobile mail route between Bern and Detligen begins on 1 June 1906 – and with that, PostBus is founded. Since then, the route network has been steadily expanded. Today, passengers can travel through Switzerland on around 1,000 PostBus routes.

  • 1919 – 1922

    First journey over a mountain pass.

    The first PostBus route to cross an Alpine pass opens in 1919, over the Simplon. In 1921, the first Postbuses travel over the Furka Pass and the Grimsel Pass, followed by the Gotthard in 1922. The journeys over the Alpine passes are the start of a new era: PostBus trips are now also a leisure activity.

  • 1924

    The birth of the famous “Du-Da-Do” three-tone horn.

    The three-tone horn can be heard on mountainous postal routes. Its purpose is to warn other road users at blind spots on narrow roads. The “C-sharp - E - A” tone sequence is based on the overture to Gioachino Rossini’s “William Tell”.

    Start of multiple pass journeys through the Central Alps.

    These journeys are still an iconic aspect of Swiss tourism. Today, PostBus offers five different mountain pass routes in the Central Alps. The most legendary is the four-pass route from Meiringen via Grimsel, Nufenen, Gotthard and Susten: with a journey time of 8 hours and 46 minutes, PostBus route 682 is the longest direct public transport service in Switzerland.

    PostBus is awarded the licence for bus routes in Liechtenstein.

    PostBus takes charge of the licensed routes in the Principality of Liechtenstein as a subcontractor. 72 years later, in December 2021, PostBus’s time in neighbouring Liechtenstein comes to an end. By that point, PostBus operates 14 routes with over 40 buses and a network of more than 100 kilometres.

    PostBus launches its first school bus services.

    Travel safely from your front door to your school building with PostBus. Thanks to PostBus’s school bus services, even families in remote villages and hamlets can send their children to school without having to use a private vehicle. This public service also makes a significant positive contribution to the environment.

    The buses used by private PostBus operators are now yellow, too.

    Previously, each company used their own corporate colours on their vehicles. PostBus operators are private companies that operate around half of the network on behalf of PostBus. Operations run by PostBus itself are known as municipal operations. Passengers do not notice the difference, as the vehicles and the drivers’ clothing have the same design.

  • 1961

    The last horse coach service is discontinued. It runs on the Juf–Avers route.

    By 1930, the horse coach service has become almost irrelevant. It serves only 0.6% of passengers travelling on 94 routes covering a total of 596 kilometres. Despite this, the last horse coach service runs between Cresta and Juf in Graubünden until 1961.
