“…The first steam locomotive undoubtedly heralded a transformative era, and since their inception in the early 19th century, railways have remained central to public transport [ 1 ]. Recently, the potential of railways to alleviate road and air congestion and environmental challenges has brought them back into the spotlight [ 2 ].…”

To date, significant progress has been made in the field of railway anomaly detection using technologies such as real-time data analytics, the Internet of Things, and machine learning. As technology continues to evolve, the ability to detect and respond to anomalies in railway systems is once again in the spotlight. However, railway anomaly detection faces challenges related to the vast infrastructure, dynamic conditions, aging infrastructure, and adverse environmental conditions on the one hand, and the scale, complexity, and critical safety implications of railway systems on the other. Our study is underpinned by the three objectives. Specifically, we aim to identify time series anomaly detection methods applied to railway sensor device data, recognize the advantages and disadvantages of these methods, and evaluate their effectiveness. To address the research objectives, the first part of the study involved a systematic literature review and a series of controlled experiments. In the case of the former, we adopted well-established guidelines to structure and visualize the review. In the second part, we investigated the effectiveness of selected machine learning methods. To evaluate the predictive performance of each method, a five-fold cross-validation approach was applied to ensure the highest accuracy and generality. Based on the calculated accuracy, the results show that the top three methods are CatBoost (96%), Random Forest (91%), and XGBoost (90%), whereas the lowest accuracy is observed for One-Class Support Vector Machines (48%), Local Outlier Factor (53%), and Isolation Forest (55%). As the industry moves toward a zero-defect paradigm on a global scale, ongoing research efforts are focused on improving existing methods and developing new ones that contribute to the safety and quality of rail transportation. In this sense, there are at least four avenues for future research worth considering: testing richer data sets, hyperparameter optimization, and implementing other methods not included in the current study.

The article is devoted to the study, generalization and systematization of scientific knowledge about the history of the establishment, development and operation of the regional railway system in Bukovyna in the second half of XIX – early XX centuries. The authors attempted to analyze the process of creation and operation of railways in Bukovyna during the reign of the Austro-Hungarian Empire based on a wide range of previously unpublished archival documents, periodicals, statistical literature and memoirs. The article studies the development of organizational bases for the construction of railways, the activity of the communication network management, lists a whole range of requirements and tasks set for railway transport in Bukovyna, the progress of their implementation, considers successes and difficulties in this work. It is determined that private railways, as important transport arteries of Bukovyna, were of national importance and played a significant role in the transport system of Austria-Hungarian Empire. They served the leading economic districts of Bukovyna, acting as an integral part of production in each of them. In other words, they were used for development of local, intersectoral and interregional relations. Regional railways, first of all, played an important role in the social and economic life of Bukovyna region. In most cases, they did not carry the strategic cargo, but made it possible to connect the most remote corners of separate areas of the region into a single whole. In practice, local railways were a significant addition to the main central line, providing the latter with a greater intensity of cargo and passenger turnover and thus increasing their profitability. At the same time, the trade volume between the outskirts and the center of the Austro-Hungarian Empire was increased. It contributed to the intensification of economic development of certain districts of Bukovyna region.

This article examines how the socio-economic conditions in Bukovyna influenced the formation and development of the railway network in the region. It explores whether these processes aligned with the global trends of the time. Based on the analysis of scientific literature, memoirs, and archival materials, it was found that the topic of the formation and functioning of the railway network in Bukovyna had not been systematically studied. It was revealed that the Austrian authorities, by turning Bukovyna into an internal colony of the Habsburg Empire, kept the region in the position of a raw material appendage and a market for the industry of the empire's central provinces. The tariff, customs, credit, and tax systems introduced by the imperial government supported this process, acting in the interests of Austro-Hungarian capital. The development of the railway network was aimed at ensuring the economic interests of the empire, which affected the socio-economic development of Bukovyna. In particular, the construction of railways improved the transport infrastructure, leading to increased trade and higher volumes of raw material and goods transportation. However, this development had a dual nature. On one hand, it promoted economic growth and modernization of the region, but on the other hand, it intensified Bukovyna's dependence on the central provinces of the empire, limiting its economic autonomy and the development of local industry. The article also analyzes the impact of railway construction on the social aspects of life in Bukovyna. The railway became an important factor in migration, contributing to urbanization and the growth of the working class. However, at the same time, social tensions increased due to the unequal distribution of economic benefits and the intensification of local population exploitation. The conclusions of the article emphasize the need for further research to fully understand the impact of railway development on Bukovyna in the context of the Austro-Hungarian Empire and to compare these processes with similar developments in other parts of the world.
