The sustainable development of geo-strategic transport networks plays a key role to meet the current expansion of the demand for commerce and economic growth. In this paper, a new geo-strategic railway network for freight services is designed with the purpose of meeting the needs of current and future demands for freight transport in the state of Santa Catarina, South Brazil. The freight flows of bulk cargo, containers, and refrigerated and liquid cargo observed in 2005 and 2015 and expected for 2023 have been analyzed and assigned to a fully connected railway network. The number of trains to meet all the demands has been identified. The links that would have a minimum number of daily trains running on them have also been identified and analyzed. New assignments are proposed and visualized using GIS. Next, location and technical specifications of specialized intermodal terminals focused on the customers’ and operators’ needs are discussed. The study shows that technological specifications for terminal operations play an important role when dealing with multiple freight types and contribute to better use of the existing infrastructure.

Planning And Operation

For decades, railway issues were considered, in Europe, as being almost entirely in the responsibility of the Member States. This history is even reflected in the present eu approach on railway issues which has, as one of its political priorities, the objective to ensure the interoperability of national legal and technical standards all over the eu. The development of trans-European transport networks, the upcoming of high-speed transboundary trains and the internationalisation of railway freight transport which are of relative recent date, all contribute to the greater awareness of railway impacts on the environment. Policies can no longer promote railways with the argument that rail is the most environment-friendly means of transport, but are more and more obliged to take into consideration, during the planning and operation of railways, local, provincial and regional environmental concerns. The contribution passes in review the most relevant environmental concerns with regard to railways. After a short description of the regulatory frame, the different environmental aspects of railways – land use, nature conservation, noise, water, air pollution, and waste management – are discussed. Some concluding remarks follow.

The rapid and stable development of China’s economy has driven the increasing demand for express transportation. Based on network operation, China Railway Corporation of High-speed Railway launched high-speed rail products, which have attracted wide attention from all walks of life. With the application of high-speed express trains, the market structure of express transportation in China will change dramatically, from highways as the main mode of transportation to high-speed railway transportation relying on a high-speed railway network, which will effectively reduce the environmental pollution caused by express transportation and further improve the sustainable development of the economy and the logistics industry. At present, the freight Electric Multiple Units (EMU) has been successfully developed and has entered the final test stage. In the last paper, we have introduced the theory and method of the high-speed rail express train operation plan. In addition, a train diagram is an important foundation of railway transportation organization. In order to ensure the sustainable development of high-speed rail express trains after they are put into use, based on the operation plan of high-speed rail express trains, this paper establishes a comprehensive compilation model of a high-speed rail express train diagram, considering train running time, freight flow distribution scheme, and the operation plan of freight multiple units, and an exact solution algorithm based on the Lagrange relaxation algorithm is designed. The computational results are encouraging and demonstrate the effectiveness of the model and solution method.

The greatest prospects associated with transnational rail freight are determined by the use of containers. In Russian publications, the development of containerized cargo transportation is mainly considered by analyzing the general laws of functioning of international transport corridors. At the same time, aspects affecting infrastructure diagnostics and analysis of the throughput capacity of sections of the railway network are not considered.The purpose of the study was to identify the characteristics of freight flows in the direction of the EU—EAEU—PRC, to identify infrastructure barriers that slow down the acceleration and increase in the volume of container railway freight transportation, as well as to develop a set of measures aimed at improving the competitiveness of container railway freight transportation along the transport corridors of the Russian Federation.In the course of the study, infrastructural diagnostics was carried out, which revealed a number of barriers that did not allow realizing the growth potential of transit container cargo transportation.To remove infrastructure barriers, it is necessary to implement a number of measures, the key of which are measures to increase the capacity of infrastructure at border crossings, increase the speed of trains along the railway networks of JSCo RZD, develop terminal and logistics centers that provide a wide range of services for consignors and consignees.The development of container rail freight is a strategically important area for the Russian Federation. The well-coordinated work of Russian Railways with private investors and the state in the framework of expanding and modernizing the terminal infrastructure, as well as increasing intermodal interactions, is able to overcome the existing infrastructure barriers and ensure the growth of container transit in the required volumes.

Resumen Los Sistemas Globales de Certificación de Sostenibilidad Barrios BREEAM-CM y LEED-ND han sido desarrollados en países de primer mundo, donde las normativas de construcción son altamente exigentes. Actualmente, se encuentran muy presentes en Latinoamérica, incluso en países como Paraguay, donde aún no existe un marco sólido sobre el cual anclar el desarrollo sostenible de las ciudades. El objetivo de esta investigación es verificar la viabilidad de estos sistemas globales en un contexto distinto al de su origen, como Asunción. Es la primera vez que se analiza al detalle la aplicación de las especificaciones técnicas de estos sistemas en este entorno y, para ello, se han creado parámetros con los cuales poder verificar qué requerimientos y especificaciones son posibles, imposibles o necesitan ser discutidos con profesionales del área, antes de considerar conveniente su aplicación. Como resultado, se ha constatado que ambos sistemas necesitan modificar o flexibilizar ciertos requerimientos y especificaciones obligatorios, cuyo incumplimiento impide actualmente la certificación de barrios en Asunción. Finalmente, se ha desarrollado una metodología capaz de verificar la viabilidad de implantación de estos sistemas no sólo en Asunción, sino en cualquier ciudad del mundo.Abstract The Global Sustainability Certification Systems Neighborhoods BREEAM-CM and LEED-ND have been developed in first world countries where construction regulations are highly strict. Currently, they are very present in Latin America, even in countries like Paraguay, where there is still no solid framework on which to anchor the sustainable development of cities. This research is to verify this global systems feasibility in a different context from their origin, such as Asunción. It is the first time that the application of the technical specifications of these systems is analyzed in detail in this environment, and, for this purpose, new parameters have been created in order to verify which requirements and specifications are possible, impossible or need to be discussed with local professionals before considering its application as meaningful. As a result, it has been found that both systems need to modify or flexibilize certain mandatory requirements and specifications, the failure of which currently prevents the neighborhoods certification, and through this will be able to work in Asunción. Finally, it has been developed a methodology capable of verifying the feasibility of implementing these systems not only in Asunción, but in any city in the world.

Regulation (EU) No 1315/2013 defines actual scope of core and comprehensive TEN-T network, including both networks for railway freight transport. For the core network, possibility to operate 740 m long freight trains is required. The aim of this paper is to analyse availability of appropriate overtaking tracks for 740 m long freight trains. Due to ETCS braking curves and odometry, such trains, after ETCS implementation, will require 780-800 m long overtaking tracks. For practical reasons (e.g. bypass lines), whole Czech railway TEN-T network is analysed. The overtaking track, whose occupation means influence on scheduled traffic or threat to boarding passengers, are excluded. The data was collected from station schemes from Collection of Official Requisites for 2015/16 Timetable, issued by SŽDC, Czech state Infrastructure Manager. Most of appropriate tracks are over 800 m long, but their density in the network and in particular directions varies considerably. For freight traffic, gradient of the line is important, so in the resulting figure, there are marked significant peaks for particular lines as well. Czech TEN-T lines are further segmented on the basis of number of tracks and their traffic character. Then, specific issues on overtaking or crossing of 740 m long freight trains are discussed. As a conclusion, for long-term development of Czech TEN-T lines, targeted investment is recommended not only for passenger railway, but also for freight railway. An attractive capacity offer for railway undertakings, which can stimulate freight traffic on European Rail freight corridors, can be represented by network-bound periodic freight train paths with suitable long overtaking tracks outside bottlenecks. After the overtaking by passenger trains, a freight train should run without stop through large node station or a bottleneck area. Before the sections with high gradients, coupling of additional locomotives should be connected with the overtaking process. Next suitable overtaking tracks should be available behind every significant peak of the line.

The reliability of high-speed railway network is an important issue for the sustainable development of railway traffic. A high reliable railway network not only has a longer service life but also has a greater ability to resist destruction of the network. In this article, based on the theory of complex network, we construct a topological networked model to study and analyze the reliability of high-speed railway network with respect to the destruction caused by natural disasters, geological disasters, equipment failure, or man-made disasters. In real world, heavy rain and snow storms are frequent on a large scale. These destructed regions are represented by network communities. Here, we put forward an evaluation index to quantify the network reliability. Taking China high-speed railway network as an example, the results show that some key communities has great influence on the network reliability. When these key communities are destructed by some natural factors, the reliability of railway network would reduce greatly or even breakdown. In addition, we find that the network reliability with the number of deleted communities approximately shows an exponential law.

Traffic Disturbance

This paper proposes a monitoring approach based on stochastic fuzzy Petri nets (SFPNs) for railway transport networks. In railway transport, the time factor is a critical parameter as it includes constraints to avoid overlaps, delays, and collisions between trains. The temporal uncertainties and constraints that may arise on the railway network may degrade the planned schedules and consequently affect the availability of the transportation system. This leads to many problems in the decision and optimization of the railway transport systems. In this context, we propose a new fuzzy stochastic Petri nets for monitoring (SFPNM). The main goal of the proposed supervision approach is to allow an early detection of traffic disturbance to avoid catastrophic scenarios and preserve stability and security of the studied railway networks. Finally, to demonstrate the effectiveness and accuracy of the approach, an application to the case study of the Tunisian railway network is outlined.
