This article is aimed at analyzing different methods of calculation of railway capacity of lines and applying them in "Lithuanian Railways", improving efficiency of railroad traffic management by using new and modern technologies, integrated into the new Traffic Management Centre (TMC) and its related systems, allowing the compression of railroad traffic schedule and facilitating conflict resolution during planning time by using new technologies. To assure new traffic prevision for "Lithuanian Railways", a new calculation method must be used, as today it is being used an old analytical method for capacity calculation on railway line, and this old calculation method does not allow the optimization of the use of the railway network. It is necessary to analyze new programming methods for calculating the train graph and its compression to adopt it in order to optimize the use of the network. This paper will present three methods used for calculating capacity consumption on railway lines and the results of applying one of them, the UIC 406 method, in a practice case. The practice case consist of adding two new trains in an already calculated schedule for the increment of the use of a line, using the new techniques for automatically detect the conflicts that appear after adding these new trains and solving the conflict. This paper will also present the statistical of how passenger's train demand increases passengers flow.

This article focuses on analyzing the systems and methods used for the interval regulation of train movement on “Rail Baltica” line in “Lithuanian Railways”. The method discussed in the article can be viewed as a combination of several management automation solutions and it is based on the implementation of the European Railway Traffic Management System (ERTMS). As it is known, the ERTMS provides an interoperable European railway network. The primary objective is to improve the quality of train traffic and to make railway transport safer and more comfortable. In order to ensure new traffic prevision for Lithuanian Railways, new interval regulation methods and traction calculations must be used. This developed method is more useful than the previous methods as it allows to shape an efficiently automated and optimized scheduling process as well as to improve line capacity and efficiency. This paper proposes the development of a moving block train control system. The calculations were made using the intervals between trains. The interval and block-section borders are not fixed by traffic signs or traffic-lights. Instead, they move after the train in the front, creating a flexible interval regulation system. The results showed that the implementation of the method had a positive impact on the operators’ performance and allowed to reduce energy consumption and to increase the speeds of train movement. The paper also presents a statistical figure portraying railway accidents and railway operation accident reports before and after the implementation of the ERTMS. The results of the analysis showed that the implementation of the European Train Traffic control systems and the interval regulation of train movement method will provide high throughput and carrying capacity, traffic safety and also increase the productivity of operation procedures.
