    Sammanfattning : Up to the middle of the 19th century the distribution of mail, public as well as private, was, to a large extent, a duty imposed on farmers. Demands from farmers to be relieved of this duty resulted in the Government giving the Post Office authority to set up post offices of a new, relatively simple kind (poststationer, or sub-post offices).

  5. 9. Dwell time delays for commuter trains : An analysis of the influence of passengers on dwell time delays

    Författare :Ruben Kuipers; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dwell time; Passengers; Delays; Trains; Railway; Station; Automatic passenger count data;

    Sammanfattning : The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. LÄS MER

  7. 10. Availability Analysis of Frequency Converters in Electrified Railway Systems
