  1. 1. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation

    Författare :Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway operation; Railway capacity; Single-track; Double-track; Partial double-track; Inter-station distance; Delay; Delay propagation; Crossing; Overtaking; Timetable flexibility; Simulation; Experimental design; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. LÄS MER

  3. 2. Quality on single-track railway lines with passenger traffic : Anlytical model for evaluation of crossing stations and partial double-tracks

    Författare :Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Nils Olsson; KTH; []
    Nyckelord :Railway operation; Railway capacity; single-track; crossing station; partial double-track; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Railway transportation is showing a substantial increase. Investments in new infrastructure, new fast and comfortable vehicles, and high frequency of service are important factors behind the increase.Infrastructure configuration and timetable construction play important roles in the competitiveness of railway transportation.

  4. 3. Efficiency of the trackwork scheduling process in Sweden

    Författare :Daria Ivina; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railways; Maintenance management; Trackwork scheduling; Project Uncertainties; Lean; Efficiency;

    Sammanfattning : Efficient scheduling is vital for railway maintenance, which is increasingly challenged by rising train traffic and infrastructure wear. Trackwork often necessitates the reduction of train speeds and the partial or complete closure of tracks. LÄS MER
