Stable operation of railway transport is of decisive importance in the development of the country's economy. Railway stations of the Russian Railways network perform a significant amount of work on processing and handling train traffic.Large technical stations on the Russian Railways network in most cases are located at the junction of railways (railway polygons), where locomotive crews and locomotives changes take place as well as various types of traction (electrified lines with direct and alternating current).With the development of polygon technologies on the Russian Railways network, it becomes necessary to optimize the traction resource management process to ensure the stable operation of train traffic from its origin to the point of its destination. At technical stations with locomotive turnover points, they are changed, as well as maintenance (TO-2) and equipment.The article discusses in more detail one of the elements of the daily budget for the use of locomotives — finding locomotives in one of the types of downtime — at the locomotive maintenance point. As an example of the queuing of traction resources, the point of maintenance of locomotives of the Karymskaya station is given, where the stalls for performing TO-2 are one of the types of devices of the locomotive economy, according to which the available capacity of the locomotive circulation section is determined. Based on the analysis of the results of the operation of the locomotive maintenance point of the Karymskaya station for 2017, a method has been developed that allows, using in the calculations the minimum interval for the supply of trains to the station, to determine the rational number of stalls mст, necessary for the development of promising volumes of freight transportation and increasing the capacity of railway lines.

Carbon Transport

Low-carbon transport is a priority in addressing climate change. Transport is still almost totally dependent on fossil fuels (96%) and accounts for almost 60% of global oil use. Sustainable transport systems, both passenger and freight, should be economically and technically feasible, but also low-carbon and environmentally friendly. The calculation of greenhouse gas emissions in transport projects is becoming a primary target of transport companies as a part of an endeavor for low-carbon strategies to reduce the energy demand and environmental impact. This paper investigates the CO2 impact of construction and operation of the main highway and railway line infrastructure in Greece, which connects Athens and Thessaloniki, the capital and the second biggest city in Greece respectively and provides a comparative analysis in roadway and railway transport.

This article provides the analysis of the possibilities to instal new technologies in the Lithuanian railways the building of a high speed railway line I in Kreta corridor. It is advisable to project this line as a mixed one, i.e. intended for both passenger and goods traffic. The research carried out by the author has shown that light transport dominates in passenger transportation among four cities of Lithuania Vilnius, Kaunas, Klaipeda and Siauliai, which transports even 81,3% of direct passengers. Buses carry 14,9% and only 3,8 % of passengers are carried by railway transport. Therefore the main problem public transport is facing is to“get the passengers back” from light transport means, i.e. cars. The prospective railway and road transport markets in local, intercity and international passengers' transportations are also established in this work.

Decision Making Support

Decision-making support systems in railway transport are systems that make it easier for traffic controllers and dispatchers involved in the regulation of train traffic to make individual decisions more easily and accurately. Without such systems, dispatchers usually make decisions based on previous experiences and feelings they have developed working in train traffic control. However, quality decision-making support systems are based on large amounts of data processed by one or several different artificial intelligence techniques. This paper will examine the architecture of such a system in railway transport, which helps the dispatcher to make decisions based on different criteria and values of individual criteria. The architecture of this decision-making support system has been developed to equal or, if necessary, use the maximum available double-track railway line capacity to resolve delays caused by lack of capacity for any given route. This system has been developed for the specific configuration of a double track, whereby each track is intended for one direction of train traffic. This paper will lay the foundation for understanding decision-making support systems and for the development of a specific model of decision-making support system in practice.

This paper presents and analyses the redefined Rijeka railway junction. The redefined concept of the Rijeka railroad hub in the context of port and railway interdependence dictates the need to find the accommodation of cargo transport to peripheral locations such as: Krasica, Kukuljanovo, Bakar, Ivani, Bršica and capacity for the island of Krk, while passenger transport would be implemented in the urban area. The most important projects related to Rijeka rail transport system are the construction of a new line of high efficiency between Zagreb and Rijeka, and a new railroad through the tunnel of Učka which will link the ports of Rijeka, Koper and Trieste. Together with the reconstruction of cargo stations Rijeka and Brajdica, an extension of the other tracks on the railroads Škrljevo-Rijeka and Rijeka-Opatija/Matulji should be performed as well as the construction of Krasica, Ivani, Tijani and Vrgljevo stations. The construction includes a multipurpose bridge to the Island of Krk and a railway line to the new container terminal as well as the new railway bypass to “elevation 200”.

The paper presents results of the study phytotoxicity level of soil that are contaminated due to the operation of the railway. The urgency of the work is determined by the growth of man-made load on the environment by rail. The aim of the presented work was to assess the phytotoxicity of soils near railway tracks using a bioassay for watercress to determine the level of their anthropogenic pollution. The object of the study were soil samples taken in the area adjacent to the tracks on the section of the railway Bakhmach-Hrebinka near the station of the city Pyriatyn. Soil sampling was carried out in accordance with DSTU ISO 10381-1: 2004. Assessment of soil contamination was assessed by bioindication using watercress test. According to the results of the research, it was found that the germination energy, seed germination and growth rates of watercress plants decreased on soil samples taken closer to the railway tracks. Weak levels of contamination were observed on soils selected at a distance of 5 meters from the railway, germination energy and seed germination were - 58 and 77%, respectively, the remaining samples did not show a significant effect on the sowing quality of watercress seeds. It was found that in plants grown on sample 4 (100 meters from the railway tracks) the length of the root system was 46 mm, while in samples 1, 2, 3 the indicator decreased respectively by 50, 32 and 9%, . The aerial part of watercress plants grown on 4 samples was 42 mm, while in samples 1,2,3, the figure decreased respectively by 43, 9 and 2%, . Therefore, it can be argued that the soil samples taken in the area adjacent to the tracks on the railway line Bakhmach-Grebinka, at a distance of 5 meters from the tracks, are low-contaminated, while the rest of the samples according to research are unpolluted and meet sanitary requirements on planning and development of settlements.

Proper cooperation the current collectors and the overhead line is a pre-requisite for reliable and safe operation of railway transport. Instances of maladjustment and, in some cases, damage to the current collectors, occur between periodic inspections of the rolling stock. In order to detect such anomalies quickly, the test stand was developed, with the aim of monitoring the technical state of the current collectors under operating conditions. The detection procedure is based on the monitoring and analysis of contact wire uplift caused by the pressure of the current collector, as the train passes through the measuring point located on the railway line and is designed with the aim of detecting collectors with incorrect values of a contact force.
