The transport market of operator companies of various forms of ownership in Ukraine is constantly evolving, but the tasks associated with the selection and implementation of the priorities of the development of the transport market, the provision of railway services by the carriers - owners of rolling stock, are not fully resolved. There is no regulatory framework that determines the procedure for choosing the priorities of transport market development, their status is not defined, the relation of the selected priorities with the budget of Ukraine is not defined. Therefore, the task of improving the mechanism for selecting scientific and technological priorities for the development of these processes is relevant.

Abstract It is a challenge for the dynamic inspection of railway route for freight car transporting cargo that out-of-gauge. One possible way is using the inspection frame installed in the inspection train to simulate the whole procedure for cargo transportation, which costs a lot of manpower and material resources as well as time. To overcome the above problem, this paper proposes an augmented reality (AR) based dynamic inspection method for visualized railway routing of freight car with out-of-gauge. First, the envelope model of the dynamic moving train with out-of-gauge cargo is generated by using the orbital spectrum of the railway, and the envelope model is matched with a piece of homemade calibration equipment located on the position of the railway that needs to be inspected. Then, the structure from motion (SFM) algorithm is used to reconstruct the environment where the virtual envelope model occludes the buildings or equipment along the railway. Finally, the distance function is adopted to calculate the distance between the obstacle and the envelope of the freight car with out-of-gauge, determining whether the freight car can pass a certain line. The experimental results show that the proposed method performs well for the route selection of out-of-gauge cargo transportation with low cost, high precision, and high efficiency. Moreover, the digital data of the environments along the railway and the envelope of the freight car can be reused, which will increase the digitalization and intelligence for route selection of out-of-gauge cargo transportation.

Abstract The article proposes a method for determining the rational motion intensity of specific train traffic flows on railway transport corridors with account for balance of expenses on traction resources and cargo owners. A mathematical model based on stochastic optimization is developed, which allows to optimize, in the conditions of risks, the interval between trailing trains on the railway lines taking into account the limited resources of the traction rolling stock, the capacity of the stations and freight fronts at the cargo destination point. Solving this mathematical model allows to find a balance between the expenses for movement of train traffic flows from different railway lines to their terminal reference station and the expenses of a consignee, subject to the limitations of the technological logistics chain in cargo transportation. For the solution of this mathematical model, a Real-coded Genetic Algorithm (RGA) was used.

Choosing a high-speed rail vehicle depends on many factors. On the one hand, there are requirements for ensuring the quality of service for passengers, on the other hand, there are constraints resulting from the parameters of available infrastructure. Also a relation of the benefit and financial costs associated with the purchase and the operation of rolling stock is essential. Technical characteristics of vehicles selected for operating a particular system is a compromise between the three groups of requirements. In this article technical parameters of railway infrastructure and rolling stock are classified and then analysed from the TSI requirements point of view.

Calculation Unit

Fitting platforms of variable freight storage lengths are used for transportation of rails and other cargo up to 25 m long. The use of innovative fixation for transportation on the fitting platforms contributes to enlargement of the range of cargo transported on such rolling stock and establishes conditions for safe transportation of such cargo.To evaluate the effectiveness of the arrangement of long cargo transportation on the fitting platform, this study examines two 25 m long rail transportation options. The transportation option involving two coupled 14.62 m platforms, when the cargo is fixed on the coupled platforms with the standard method is the basic option. The new option involves transportation of the 25 m long rails using 80-feet fitting platforms 25.62 m long at the coupling axes and multiway fi xation sets. A calendar year is assumed as the estimate period. The transported volume is assumed equal for each option, under considering the operating conditions of the calculation unit — one coupling of universal platform (or one 80-feet fitting platform), reducing the financial results to a ton of transported cargo. The value of the annual economic effect for the freight owner (Eyearown) is determined as the change of the freight owner’s expenses due to usage of the new option relative to the basic transportation option.The economic assessment of the transportation is performed considering the interests of each member of the transportation process and tested based on specific data. The results demonstrate the effectiveness of implementation of the technical and technological solution under consideration.

The Impact

In the article was noted the importance of the study of the conditions for the carriage of goods by rail transport when executing the railway transport examination, and the main points of such studies are given. One of the causes of the onset of a railroad accident (hereinafter referred to as RTA) with damage to the rolling stock, infrastructure elements, loss of life and loss of cargo through damaged packaging, the integrity of the car body may be a mismatch of the cargo weight with established weight standards, unsatisfactory the technical condition of the rolling stock in which the cargo is transported, improper securing of the cargo in the car, disorder of attachment on the route or interference of unauthorized persons to the cargo itself (theft). As a part of the railway-transport expertise, experts investigate cases of derailment of railway rolling stock, spontaneous movement of cars from the parking lot, followed by their collision, and other cases. Upon the occurrence of an RTA, the compliance of the actions of the railway employees involved with the requirements of regulatory documents, the causal link and the immediate technical reason for its occurrence is investigated. Experts carrying out research within the examination regarded various possible discrepancies that could cause the occurrence of RTA. The inconsistency of the mass of the cargo with the established weight standards for transportation by rail is considered by experts, precisely as a possible discrepancy that could significantly affect the occurrence of the accident. This direction of research requires detailed consideration from the position of forensic expertise. The article discusses individual issues of this type of inconsistency. These points are considered in more detail in a research work devoted to a study of the main transport characteristics of the goods transported and their packages, with an assessment of the possibility of their influence on the causal relationship with the onset of the RTA as part of the railway transport expertise. Each type of faults (inconsistencies) identified during the carriage of goods by rail is investigated as part of the implementation of forensic railway transport examinations and requires the formation of detailed expert approaches. The presented work confirms the relevance of developing a methodology for assessing the impact of cargo transportation features on the onset of railway accidents. Key words: commercial malfunctions, forensic railway-transport expertise, cargo, features of transportation, fasteners, weight standards.
