One of the main tasks of the long-term expansion of the Lithuanian railway transport is to ensure, following the European Union legislation, the implementation of a reform of the Lithuanian railway transportation sector so that the competitiveness of the country's railways in the European transport services market is increased. To properly implement the aforementioned objective, it is crucial to understand and to carry out a careful analysis on the existing railway management models (the separated one, the integrated one following the principle of holding and a completely integrated one). Only once all the pros and cons of the railway management models have been analyzed, one can choose the most optimum option for Lithuanian railways. This article will look at the advantages and disadvantages of the integrated model on the basis of the German railways. The article analyses the review of the German railway management model, the structure of the railway system, the criticism of the Deutsche Bahn model is provided in it along with the advantages of the German model.

This paper analyzes the influence of transient operating modes in the Cat 3512B-HD and MTU 4000 R41 locomotive diesel engines on their energy usage. This analysis represents an integral component of the technological research and development performed at Lietuvos Geležinkeliai AB (JSC Lithuanian Railways) with the objective of increasing the efficiency of freight transportation with the upgraded 2M62M and modern ER20CF/2ER20CF diesel locomotives. The influence of transient modes on the operating variables of the locomotive diesel engines was evaluated under operational load-cycling conditions to aid in the selection of appropriate parameters (e.g., the train weight, the diesel locomotive type, and the technical characteristics of the diesel locomotive to be modeled) for freight transportation on Lithuanian railway lines. It was determined that the engine’s electronic control system compensates for the negative effects of transient operations on the engine’s energy usage. As a result, the increase in fuel consumption is less than 3% during transient operation when compared to steady-state operation. Through this research, methodological foundations have been formulated and adapted for the use of the mathematical modeling of the transient modes of locomotive diesel engines to optimize freight transportation, resulting in an expected decrease of 10–15% in fuel consumption.

A mathematical model to select the best rolling stocks of trains is introduced. The parameters of income and cost of the passenger transportation by railways depending on the technical characteristic of used vehicles are thoroughly evaluated. The options how to reduce the cost calculated by a model in one of the specific routes of Lithuanian Railways are given and practical decisions are argumentatively given. [ABSTRACT FROM AUTHOR]
