1980

On 2 September 1980, the new Saurer RH 580-25 underfloor coach service is inaugurated. The vehicle marks the launch of radio technology on route 74, Sursee–Beromünster. This is the technology used between vehicles until the iPhone is introduced in around 2008. On board for the inaugural journey is Adolf Hüsler (in 2025 now chairman of the board of directors of PostBus operator SB Trans GmbH), along with his uncle August Hüsler and grandfather Alfred Hüsler (former mayor of the municipality of Rickenbach), both of whom were also PostBus operators.
