Malpensa Airport North Railway Link: impact of expected traffic onto the existing network Faculty of Civil and Industrial Engineering Department of Civil Constructional and Environmental Engineering Master Degree in Transport Systems Engineering Candidate: Filippo Zanzarin - 1746819 Supervisor Co-supervisor Prof. Stefano Ricci Ing. Emmanuele Vaghi A.A. 2017-2018 ABSTRACT This work presents an analysis about the performances of the lines and the nodes involved in the upgrade process of Malpensa International Airport accessibility. This study is developed throughout a new complete analysis model consisting of the rational integration of existing methods. The methodology proposed and applied for the evaluation of the railway infrastructural upgrade solutions for the development of the connections between Milan and its airport is conveniently developed and improved according to the study requirements. The evaluation of line and node capacity is carried out considering the actual and future layouts of the railway network at a regional level and the actual and planned services offered by the railway supplier. The results obtained recommend infrastructural upgrades in order to make available the matching network capacity. The analysis of the lines and the nodes involved in this process, as well as the effectiveness of the proposed infrastructural improvements, is strengthened by a scheduling analysis and the application of a simulation method. i TABLE OF CONTENTS Abstract
