Abstract (sommario):

Abstract In developing the railway industry, the electrified railway plays a significant role in improving the national economy. However, the electric railway power supply system will be affected by power quality problems such as negative sequence, harmonic, and voltage fluctuation in actual operation, which will affect the operation efficiency of the electric railway power supply system. Therefore, it is meaningful to take economic and effectual governance measures against the power quality problems of electrified railways and reduce various indicators to the range allowed by a national stand

AbstractTransport is a very important part of activities in the tourism sector. In addition to the transport of tourists to and within a destination, transport itself can be a tourist attraction. The aim of this paper is to analyse selected problems of railways in Slovakia (a decrease in the importance of railways for passenger transport in Slovakia in the past 20 years, discontinued passenger transport on certain railway tracks and the modernisation of other tracks, and zero-fare public rail transport services for certain categories of passengers), and to present good examples of the use of n

Abstract (sommario):

It is known that the effective functioning of the railways depends on their load-bearing capacity, and therefore, special attention is paid to the pre-feasibility study and the payback period of the capital investments invested in the works during the capital investments of the railways. Because the operation of railway lines is associated with significant costs, its existence within the allowable limits of its size requires periodic evaluation and planning and implementation of engineering measures.

Abstract (sommario):

The article highlights the state of transport communication in Karakalpakstan during the Second World War. With the beginning of the war, the entire transport system of the republic was reorganized. All its activities were aimed at meeting the needs of the front. Most of the cars and tractors were mobilized to the front, shipping and railways were heavily burdened. The republic had sea and river transport, through which all cargo flows were carried out. The republic had transport links through the Aral and Amu Darya shipping lines and had access to large railway lines.

Abstract (sommario):

JSC Russian Railways has a number of unresolved issues in the field of pricing and regulation of freight transportation tariffs. The company receives its main income from freight transportation. For 9 months of 2024, their volume amounted to more than 80%. Freight transportation provides the main financial position of the industry. The current regulatory framework for determining tariffs was formed in the 2000s. Recently, the rules for reforming railway tariffs have been actively discussed. At JSC Russian Railways, freight transportation prices are formed in such a way that the loading of low-

Abstract (sommario):

Recovering the timetable after a delay is essential to the smooth and efficient operation of the railways for both passengers and railway operators. Most current railway rescheduling research concentrates on static problems where all delays are known about in advance. However, due to the unpredictable nature of the railway system, it is possible that further unforeseen incidents could occur while the trains are running to the new rescheduled timetable. This will change the problem, making it a dynamic problem that changes over time. The aim of this work is to investigate the application of ant

We provide evidence on the link between infrastructure development and the distribution of income for the period 1960-1995. To do this, we use several proxies such as roads, railways, telecommunications and energy measures. The approach is comprehensive as cross-country and panel methods are applied. In the latter case, we apply GMM dynamic panel methods in order to minimize for endogeneity problems. Both quantity of infrastructure and quality of infrastructure are negatively linked with income inequality. The quantitative link tends to be stronger in developing countries than the qualitative
