  1. 1. Railway traffic disturbance management

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Johanna Törnquist; Blekinge Tekniska Högskola.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Railway traffic; Transportation; Re-scheduling; Disturbance management; Decision support systems;

    Abstract : With the increasing traffic volumes in many railway networks and reports on capacity deficiencies that result in insufficient punctuality and reliability, the need for efficient disturbance management solutions becomes evident. This thesis focuses on solutions that aim to minimise the consequences of disturbances for the various stakeholders and specifically on methods for re-scheduling the traffic. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Olov Lindfeldt; KTH.; [2010]
    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; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP 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

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

    University dissertation from KTH Royal Institute of Technology

    Author : Olov Lindfeldt; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway operation; Railway capacity; single-track; crossing station; partial double-track; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. 4. Characterisation of airborne particles from rail traffic

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Saeed Abbasi; KTH.; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; airborne; railway; brake; block; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik Övrig teknisk mekanik; SRA - Transport; SRA - Transport; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för godstrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Effektiva tågsystem för persontrafik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : Since the investigation of wear particles in rail transport started in late-1910s, the high mass concentration of these particles has raised worries among researchers concerned with air quality. However, effective action has yet to be taken because of lack of relevant knowledge. READ MORE

  5. 5. Computer-based decision support for handling uncertainty in railway traffic and transportation

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Johanna Törnquist; Blekinge Tekniska Högskola.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Railway scheduling; train traffic; transportation; agent systems;

    Abstract : Railway transportation has great potential, but interdependencies in the railway traffic make trains very sensitive to disturbances, which can bedifficult to handle. Using railway in an intermodal transport chain may complicate the interconnections with other modes if there is large uncertainty in the performance of the railway. READ MORE
