In 1971, the Bundespost agreed to build up a joint venture cooperation with the Bundesbahn rail bus network and from 1981, the service was split into regional transport companies under the umbrella of the Bundesbahn authority, running bus lines in major cities and metropolitan areas associated with each other. By 1995, the newly established Bundespost successor, the privatized Deutsche Post stock company, had retired completely from bus service and the yellow vehicles disappeared from public roads. However, there are foreign postbuses in Germany with international scheduled services (e.g. from Austria in the Berchtesgadener Land area and in Oberstdorf; from Switzerland in southern Baden-Württemberg).
