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

    Author : Olov Lindfeldt; Bo-Lennart Nelldal; Lars-Göran Mattsson; Ingo Hansen; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

  5. 3. Assessment of Robustness in Railway Traffic Timetables

    Author : Emma V. Andersson; Jan Lundgren; Anders Peterson; Johanna Törnquist Krasemann; Thorsten Büker; Linköpings universitet; []
    Keywords : ;

    Abstract : A tendency seen for the last decades in many European railway networks is a growing demand for capacity. An increased number of operating trains has led to a delay sensitive system where it is hard to recover from delays, where even relatively small delays are easily propagating to other traffic.
