  1. 1. A Digital Test Bench for Pneumatic Brakes

    University essay from KTH/Spårfordon

    Author : Bastian Schick; [2021]
    Keywords : Compressed air brake; Freight train; Modular simulation; Pneumatics; Railways; System modelling; Tryckluftsbroms; Godståg; Modulär Simulering; Pneumatik; Järnväg; Systemmodellering;

    Abstract : This master’s thesis covers the structuring and implementation of a digital testbench for the air brake system of freight trains. The test bench will serveto further improve the existing brake models at Transrail Sweden AB. Theseare used for the optimised calculation of train speed profiles by the DriverAdvisory System CATO.

  2. 2. Developing Markov chain models for train delay evolution in winter climate

    University essay from Umeå universitet/Institutionen för fysik

    Author : Frej Sundqvist; [2021]
    Keywords : Markov chains; Train delay;

    Abstract : The traffic on Swedish railways is increasing and punctuality is of important matter for both passenger and freight trains. The problem of modeling train delay evolution is complex since conflicts between trains can occur and since a delay can have a wide variety of causes. Swedish railways faces in addition harsh winter climate. READ MORE

  3. 3. The effects of emerging technologies in rail yards and intermodal terminals

    University essay from KTH/Transportplanering

    Author : Branko Mitrovic; [2019]
    Keywords : Intermodal Transports; Rail Freight; Emerging Technologies; Automation; Digitalization; Marshalling yard; Intelligent Video Gate.;

    Abstract : This paper analyzes the effects of emerging technologies in intermodal terminals and marshallingyards, based on “Intelligent Video Gate” project within the H2020 – Shift2Rail initiative. Projectaim is to initiate the next logical step to a higher level of automation in terminals and to reduce thelead-time needed for the identification/verification process of freight trains.

  4. 4. Analysis of a mathematical model in Python for geographical disaggregation of freight growth rates based on the pivot-point method

    University essay from KTH/Optimeringslära och systemteori

    Author : Karl Hernebrant; [2019]
    Keywords : ;

    Abstract : One of the tasks for the Swedish Transport Agency, Trafikverket, is to provide traffic forecasts. To do this, a number of different forecast models are used, where Samgods is a nationally estimated model, where the quality of the results gets more unstable the more disaggregated level you are looking at.

  5. 5. Samverkan mellan förvaltningsnivåer för utveckling av regional tågtrafik : en studie om möjligheter och problem i två olika järnvägsexempel och olika aktörers syn på samverkan

    University essay from SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Author : Ellinor Lundholm; [2019]
    Keywords : samverkan; regional tågtrafik; järnväg; flernivåförvaltning; flernivåstyrning; aktörer; kollektivtrafik; planering; utveckling; landsbygd;

    Abstract : Idag är det krav på samverkan mellan aktörer på olika förvaltningsnivåer (nationell, regional och lokal nivå) inom planering och utveckling av kollektivtrafik i Sverige. De aktörer som arbetar inom området för kollektivtrafik är ofta medvetna om vikten av samverkan men forskning har visat att aktörer ändå upplever det svårt att samverka i praktiken. READ MORE
