This paper explores the arguments, both in favour of and against vertical integration in railways, taking into account liberalisation requirements according to EU-legislation. It draws on industrial economics insight and combines it with illustrations from the German railway business. Since privatisation, next to liberalisation and restructuring, is taken as a central means of strengthening the...

In this paper we describe the successful application of a sophisticated Operations Research model and the corresponding solution techniques for scheduling the 6,500+ drivers and conductors of the Dutch railway operator NS Reizigers (Netherlands Railways). In 2001 the drivers and conductors were very dissatisfied with the structure of their duties, which led to nation wide strikes. However, the ...

This paper analyses the extent and speed of railway reform in transition economies. EU-accession railways, which are financially weak and losing market share to road transport, have advanced on the railway reform path more than cash-flow rich CIS railways, which enjoy a captive market in freight. Reform agendas are ambitious on paper but suffer from implementation delays. The combination of fav...

In this paper an alternative railway power systems design based on an HVDC feeder is studied. The HVDC feeder is connected to the catenary by converters. Such an HVDC line is also appropriate for DC-fed railways and AC-fed railways working at public frequency. A unit commitment optimal power flow model has been developed and is applied on a test system. In this paper, the model is presented in ...

The article explores the impact of malaria on infrastructure works--above all, railroads--under the republican drive towards modernization. Railways helped tie the territory together and foster the symbolic and material expansion of the Brazilian nation. The scientists entrusted with vanquishing such epidemic outbreaks did not just conduct campaigns; they also undertook painstaking observations...

U.S. Class I railways maintain their infrastructure through a mix of ordinary maintenance and periodic renewal of infrastructure components. Different railways use different proportions of ordinary maintenance and periodic renewal with little consensus as to the best combination. Furthermore, the cost-effectiveness of emphasizing one method over the other has not been analyzed using empirical d...

Safety systems for railways have shifted from electronic relays to more computer-oriented approaches. This article highlights the language EURIS from NS Railinfrabeheer, which champions an object-oriented method for the speciication of interlocking logics.

We consider the Train Unit Shunting Problem, an important planning problem for passenger railway operators. This problem entails assigning physical train units to scheduled train services in such a way that the resulting shunting yard operations are feasible. As such, it arises at every shunting yard in the railway network and involves matching train units to arriving and departing train servic...

Human errors are regarded as one of the main causes for railway accidents these days. In spite of this fact, the consideration of human error probabilities in quantified risk analyses has been very rudimentary up to now. A lack of comprehensive data and analyses in literature lead to the use of estimations and values from other industries. This paper discusses the transferability of human error...
