Frequent train delays make passenger-oriented train dispatching a task of high practical relevance. In case of delays, dispatchers have to decide whether trains should wait for one or several delayed feeder trains or should depart on time. To support dispatchers, we have recently introduced the train dispatching framework PANDA (CASPT 2015). In this paper, we present and evaluate two enhancemen...

high speed intercity passenger rail is an inherently strong railway application. it operates over 250 km/hour. for perspective, high-speed represents the ultimate development of preexisting standard gauge infrastructure. network of high-speed passenger rail lines aimed at reducing accident, reducing traffic congestion, air pollution cutting national dependence on foreign oil and improving rural...

Purpose In comparison to North America, railway companies in Europe are confronted with strong economic issues in running their wagonload traffic. The purpose of this paper is an analysis how infrastructural and institutional differences affect planning issues and economic efficiency. Method A particular decision problem from railway freight traffic, the Railroad Blocking Problem (RBP), is cons...

Laying ballastless track on railway bridges has the advantages of reducing the train noise problem, improving passenger comfort, and reducing track maintenance costs. Therefore, railway bridges with ballastless track have gradually turned into a major trend in railway systems all over the world. In Taiwan, railway bridges with ballastless track have been in use for many years, with ballastless ...

In this paper we introduce the problem of shunting passenger train units in a railway station. Shunting occurs whenever train units are temporarily not necessary to operate a given timetable. We discuss several aspects of this problem and focus on two subproblems. We propose mathematical models for these subproblems together with a solution method based on column generation. Furthermore, a new ...

Broken rails can cause train delays, trains cancelations and, unfortunately, they are common causes of accidents. This aff ects planning of a resources, budget and organization of railway track maintenance. Planning of railway track maintenance cannot be done without an estimation of number of rails that will be replaced due to the broken rail incidents. There are many factors that infl uence b...

Regional cooperation in rail transport can help participating countries diversify their trade patterns. Improved also attract foreign direct investment, increase participation global production networks and the scale of related manufactured goods, exports. infrastructure will competitiveness spur economic development. In addition, improved regional integration through connectivity between peopl...

In this study, we examined ticket pricing and train stop planning for the high-speed railway (HSR), which integrates two key aspects of operation organization. We considered that passenger demand is sensitive to generalized travel cost (depending on price time) plan can affect time distribution. Then, a mixed-integer non-linear optimization model was proposed joint problem maximize HSR’s transp...
