The Influence of Metro Tunnel Construction Parameters on the Settlement of Surrounding Buildings

The construction of tunnels in conditions of dense urban development affects buildings, structures, and engineering communications located at the surface. In this work, through dispersion analysis, factors influencing the settlement of the earth’s surface and buildings during tunneling were selected. Subsequently, a model based on statistically significant parameters that can predict deformations at the pre-design stage was created. This research was conducted using data from geotechnical monitoring obtained during the construction of underground structures, with information about the technological parameters of shield tunneling in the construction of the single-track lines of the Moscow Metro using TBM with face-support pressure and engineering–geological conditions. In the obtained model, there is a clear dependency between the additional displacement of the monitoring object located above the projected tunnel and the average face-support pressure causing the mentioned deformations. The response is also affected by the soil deformation model at the tunnel face, the depth of the tunnel, and the soil excavation for the installation of one ring.

Targeting RBM39 through indisulam induced mis-splicing of mRNA to exert anti-cancer effects in T-cell acute lymphoblastic leukemia

BackgroundDespite the use of targeted therapeutic approaches, T-cell acute lymphoblastic leukemia (T-ALL) is still associated with a high incidence of complications and a poor prognosis. Indisulam (also known as E7070), a newly identified molecular glue compound, has demonstrated increased therapeutic efficacy in several types of cancer through the rapid degradation of RBM39. This study aimed to evaluate the therapeutic potential of indisulam in T-ALL, elucidate its underlying mechanisms and explore the role of the RBM39 gene.MethodsWe verified the anticancer effects of indisulam in both in vivo and in vitro models. Additionally, the construction of RBM39-knockdown cell lines using shRNA confirmed that the malignant phenotype of T-ALL cells was dependent on RBM39. Through RNA sequencing, we identified indisulam-induced splicing anomalies, and proteomic analysis helped pinpoint protein changes caused by the drug. Comprehensive cross-analysis of these findings facilitated the identification of downstream effectors and subsequent validation of their functional roles.ResultsIndisulam has significant antineoplastic effects on T-ALL. It attenuates cell proliferation, promotes apoptosis and interferes with cell cycle progression in vitro while facilitating tumor remission in T-ALL in vivo models. This investigation provides evidence that the downregulation of RBM39 results in the restricted proliferation of T-ALL cells both in vitro and in vivo, suggesting that RBM39 is a potential target for T-ALL treatment. Indisulam’s efficacy is attributed to its ability to induce RBM39 degradation, causing widespread aberrant splicing and abnormal translation of the critical downstream effector protein, THOC1, ultimately leading to protein depletion. Moreover, the presence of DCAF15 is regarded as critical for the effectiveness of indisulam, and its absence negates the ability of indisulam to induce the desired functional alterations.ConclusionOur study revealed that indisulam, which targets RBM39 to induce tumor cell apoptosis, is an effective drug for treating T-ALL. Targeting RBM39 through indisulam leads to mis-splicing of pre-mRNAs, resulting in the loss of key effectors such as THOC1.

Understanding land subsidence in the Pearl River Delta region of China based on InSAR observations

Land subsidence occurs in river delta areas. A comprehensive understanding of the factors contributing to land subsidence is crucial for effective geohazard mitigation and land planning. This study investigates the distribution characteristics and spatiotemporal evolution pattern of the land subsidence in the Pearl River Delta based on the InSAR-derived ground deformation data spanning 2016 to 2021; and, the effects of the influencing factors, including the Quaternary sediment thickness, land use classification, land reclamation, and subway construction and operation, on the subsidence are analyzed. The results unveil the presence of four major subsidence zones and several minor coastal subsidence bowls in the research area, with a total area of about 1100 km, all of which exhibit prolonged and intense subsidence. In the remaining regions, land subsidence predominantly exhibits weak and short-term occurrences. The subsidence in the study area follows a distinct linear evolutionary pattern with a slight rebound, potentially linked to the rise of groundwater levels. Regions with Quaternary sediment thickness surpassing 20 m, engaging in aquaculture or agricultural activities, and featuring reclaimed land are predisposed to prolonged and intense ground subsidence. In addition, the construction and operation of subway lines may induce ground subsidence, especially in geologically vulnerable areas. This study provides valuable insights into land subsidence research in delta regions.

Transport infrastructure in ensuring regional development and China's global competitiveness

Purpose: is to evaluate the modern role of transport infrastructure as the factor in the development of the regional economy and strengthening competitive positions outside the country using the example of China.Methods: the correlation-regression analysis, traditionally used to solve the task of the identifying influencing factors, was applied to the economic and transportation indicators across 28 Chinese regions for the year 2021. It was supplemented by the analysis of statistical data and the thematic case study of data on Chinese investments into the transport infrastructure projects both domestically, and abroad.Results: the assessment of infrastructure development of the railway and port infrastructure was carried out based on the analysis of the dynamics of the main indicators. The construction of a correlation and regression analysis model made it possible to form an idea of the impact of China's transport infrastructure on the gross regional product of the provinces. The degree of penetration of Chinese influence into other economies of the world through investments in transport infrastructure has been assessed. The tools for promoting infrastructure projects have been identified that characterize Chinese specifics and make it possible to ensure the country's competitiveness at the global level.Conclusions and Relevance: China is the striking example of the widespread construction of ports, railways, and highways, in addition to the creation of direct freight vehicles and dry cargo ships for the distribution of their products. The high importance of transport infrastructure and the number of employed people in this industry for the growth of the regional product of the provinces of China has been revealed. In the external circuit, the PRC is actively using the strategy of lending to other countries for the construction of infrastructure on their territories. The construction of roads, airports, seaports, power plants and transmission lines allow China to create infrastructure enclaves in developing countries to market its goods and export raw materials for subsequent processing. Borrowing the experience of the PRC in terms of mechanisms for granting grants and loans for the implementation of infrastructure projects will allow Russia to create an extensive system of movement of national goods to markets where they are most in demand in the territories of neighboring states.

Detection of Underground Utility Pole Base for Distribution Transmission Network Based on Transient Electromagnetic Method

In the construction of overhead distribution network lines, ensuring the stability and construction quality of utility pole foundations is crucial. Traditionally, this process may involve excavation and direct inspection, which is not only time-consuming but may also cause environmental damage. The non-destructive detection scheme proposed in this paper, based on the transient electromagnetic method (TEM), offers an efficient and non-intrusive method for detecting the burial conditions of utility pole bases, pulls, and chucks. The transient electromagnetic method is a geophysical exploration technique that uses the principle of electromagnetic induction to detect the distribution of underground materials. When detecting utility pole bases, this method analyzes the electromagnetic response generated by underground metallic structures to obtain information. However, traditional TEM has a blind zone problem in shallow metal detection, which limits its application in utility pole base inspection. To address this issue, the scheme proposed in this paper introduces a decoupling coil to eliminate interference caused by the primary magnetic field. This decoupling technology significantly improves the detection discrimination, allowing for a more accurate determination of the burial depth and condition of bases, pulls, and chucks. Finite element numerical analysis using COMSOL 5.4 is adopted to examine the underground magnetic field distribution and optimize coil parameters. This analysis helps to understand the interaction between the electromagnetic field and underground structures, guiding the design of coils and the development of detection strategies. The prototype experimental platform built further validates the effectiveness of the scheme. Experimental results include measured data of magnetic field variations, assessments of detection depth and resolution. These experimental results are crucial for verifying the practical application potential of the non-destructive detection scheme.

Biodiversity on the line: life cycle impact assessment of power lines on birds and mammals in Norway

The global shift towards renewable energy plays an important role in fighting climate change. To facilitate the global growth of renewable energy production, the expansion of the electric grid becomes inevitable. Yet further construction of power lines poses a risk to biodiversity. Power lines traverse natural habitats and can lead to habitat conversion, fragmentation, and loss. Moreover, due to collisions and electrocutions, power lines kill hundreds of millions of birds each year. These impacts, however, have so far not been incorporated into decision-making. Life cycle assessment (LCA) is a widely used framework to compare environmental impacts and support decision-makers in planning and promoting sustainable strategies. We adapted existing life cycle impact assessment (LCIA) models to quantify the three main impacts of power lines on biodiversity: collision, electrocution, and habitat conversion and fragmentation. Our models incorporated species-area and species-habitat relationships to assess the effects of power lines on the diversity of birds and non-flying mammals in Norway, as the country is currently committed to reducing its emissions by expanding its renewable energy capacity. Overall, habitat conversion and fragmentation had the highest impact across the three impact categories, particularly affecting mammal richness. Furthermore, distribution lines often affected species richness more than transmission lines. The effect of the three impact pathways varied among different species groups, highlighting the vulnerability of certain species to habitat change, collision, and electrocution. Integrating LCIA models that quantify the impacts of power lines on biodiversity into LCA can support decision-makers with tools to promote the development of the electric grid without overlooking its effect on species richness. In addition, our models set the stage for a comprehensive assessment of the effects of electricity generation and transmission on biodiversity.

TBM excavation of São Paulo Metro Line 6 South in heterogeneous ground in urban area

AbstractThe São Paulo Metro is expanding its network in the São Paulo Metropolitan Area inhabited by 21 million people. Metro Line 6 connects the north of the city to the existing metro network further South. The construction of Line 6 currently represents the largest infrastructure project in Latin America, combining the excavation of tunnel boring machine (TBM) and conventional tunnels, cut‐and‐cover stations and a number of deep emergency exit shafts. This paper presents the main features of the TBM tunnel excavated in the South stretch through the Tertiary soils of the São Paulo Basin and through the challenging Embu Complex, which consists of a mixture of fractured rock, saprolite and residual soils. The alignment runs under the dense urban grid of São Paulo under high‐rise buildings and other infrastructure, such as existing Metro lines.

A Study on Deformation Characteristics and Stability of Soft Surrounding Rock for a Shallow-Buried Tunnel

The Heimaguan Tunnel in China serves as a case study to exemplify the variation laws related to surface settlement, deformation, and stress characteristics in a shallow-buried soft-rock tunnel, while emphasizing in the tunnel support requirements. The first stage of this study begins with monitoring the time-varying characteristics of surface settlement, vault subsidence, and the horizontal convergence of Grade V rock. In the second stage, Peck theory is used to calculate the distribution characteristics of surface settlement. The results of both stages are compared to create a vault settlement model, thus establishing the horizontal convergence based on exponential function, logarithmic function and hyperbolic function, and determining the optimal time of secondary lining construction. On this basis, the time-dependent variation laws and characteristics of vertical and horizontal displacement and principal stress of surrounding rock are studied. After this, using simulation and analysis, the proper support is recommended. The study reveals that the surface settlement, vault subsidence, and horizontal convergence of the shallow-buried soft-rock tunnel stabilize within 25–30 days. Peck theory closely aligns with predictions based on exponential functions, with only a 0.72% difference. The recommended time for secondary lining application is 26–27 days.

Scenarios for New Mobility Policies and Automated Mobility in Beijing

In this study, we consider the introduction of new mobility services and technologies into the megacity of Beijing, China, as per developed strategy and action plans, in order to investigate their potential contribution to sustainable mobility. This includes population relocation (decentralization), the construction of new rail lines, the introduction of shared bike services as a feeder to subway stations, the electrification of passenger vehicles and the adoption of automated and shared vehicles. The well-established, system dynamics-based MARS model is adapted to Beijing and further improved via the inclusion of these new services, technologies and policies. We find that decentralization can have a profound effect on overall sustainability if not considered in conjunction with other policies and that new rail lines and shared bikes may only have benefits in specific zones. Shared and automated vehicles could increase VKT by 60% and reduce active and public transport trips by a quarter. As such, nuanced integrated policy approaches will be required that are similar to those currently in place, such as imposed car shedding and taxi fleet control.

Development of intelligent traction walking plate for tension overhead construction

AbstractIn the process of tension wire construction of transmission lines, the key state quantities such as tension, inclination and spatial position of the traction walking plate directly affect the construction safety. At present, the construction personnel use visual observation to obtain the state quantity of traction walking plate in the process of tension wire construction. This monitoring method is not only inefficient, and there are personal subjective factors of judgment errors. For this reason, this paper develops a kind of intelligent traction walking plate for tension wire construction, based on the principle of resistance strain type and gyroscope to obtain the tension and inclination of the traction walking plate, respectively, using two front cameras and two rear cameras to obtain the spatial position of the traction walking plate, and finally completing the real‐time transmission of the monitoring data through the Lora technology. The developed intelligent traction walking plate was applied in Shandong Heze Yongfeng 220 kV transmission line project on 11 October 2020, which improved the construction efficiency by 15.71% while ensuring the construction safety.

Preventive Archaeological Research in Overhead Electric Power Line’s Construction Zones

The article is dedicated to archaeological research within the limits of projected and existing overhead power lines in Ukraine. Based on the experience of the Scientific and Research Centre “Rescue Archaeological Service” of the Institute of Archaeology, the National Academy of Sciences of Ukraine, the results of such works were summarised and monument protection measures for avoiding or mitigating the negative impact on the archaeological heritage during the overhead power lines construction were proposed. In 2008–2024 the Center’s employees surveyed 1507.3 km of power lines 220‑750 kW and 2642 hectares of area within the 14–21 m wide right of way; 444 new and known archaeological objects were localised; monument protection measures for 342 objects were developed; 8946 m2 were excavated in places where supports installed on 40 archaeological sites; 30 archaeological sites were supervised; accounting documentation for 78 monuments was developed. According to the survey results the average archaeological objects occurrence index per one kilometer of the overhead power lines planned route was determined as 0.251. It has been confirmed that in the steppe zone and adjacent areas of the forest-steppe mounds and mound groups occur more often than the settlements that prevail in the forest and forest-steppe zones. The regularities in which each stage of research defines the task for the next and gradually narrows the scope of development areas have been determined: at the Feasibility study stage an area of more than 1200000 hectares was developed; at the Project stage 2642 ha were archaeologically surveyed; at the stage of Construction monument protection research is planned on an area of 28.27 hectares. The same trend applies to the archaeology objects number covered 1358, 444 and 342 objects respectively. Despite the research areas decreasing, their resource consumption and the cost of the archaeological methods used are increasing.The United Energy System of Ukraine is one of the largest in Europe. According to its promising development program it was planned to build a thousand km of new overhead power lines. However, the war made its corrections and to the new planning construction were added hundreds of kilometers of destroyed overhead lines and dozens of ruined electrical substations. Comparing such linear objects as highways or main pipelines a much smaller volume of earthworks is processed during the overhead lines construction and they too can potentially have a significant negative impact on the environment including cultural heritage. Therefore, preventive measures developed on the mitigation hierarchy principles should be implemented at all construction stages. Each cycle’s phase corresponds to a certain type of archaeological research: planning → preliminary archival and bibliographic research; design → archaeological investigations (surveys); construction → archaeological monument protection research; exploitation → monitoring. Such approach using ensures the optimal management adoption decisions and helps to avoid and/or reduce the potential negative impact on cultural heritage even at the first stages of the investment project development.

МЕРОПРИЯТИЯ ПО ПОВЫШЕНИЮ НАДЁЖНОСТИ СИСТЕМЫ ЭЛЕКТРОСНАБЖЕНИЯ ИРКУТСКОЙ ОБЛАСТИ ПРИ МОДЕРНИЗАЦИИ И СТРОИТЕЛЬСТВЕ НОВЫХ ВЫСОКОВОЛЬТНЫХ ВОЗДУШНЫХ ЛИНИЙ

The issue of modernization and construction of new high-voltage lines in the Irkutsk region was con-sidered in the light of the requirements of the order of the Ministry of Energy of the Russian Federa-tion No. 108 dated 02/28/2023

Different Demand Response Programs with its Implementation in Various Countries and the Role of TOU DR in the Context of Nepal

With the increasing trend of electricity consumption worldwide, it creates a cumbersome, reliable power system and necessitates the construction of new generator companies, transmission lines, and other infrastructures. Despite investing in new infrastructures to manage occasional peaks, utilities can use the demand response concept to effectively handle demand during such peak time intervals, and in doing so, it enhance the grid stability. This assists in balancing the supply and demand for electricity, making the grid more resilient to fluctuations, and reducing the risk of blackouts. This paper delves into the diverse DR programs across different countries and comparative analysis for finding the suitable DR method to make a more reliable electric power network in Nepal.

Exploring the psychological and emotional burden of compulsory acquisition: a case study of New Akrade-Mpakadan, Ghana

PurposeThis paper aims to explore the psychological, emotional and equity implications of compulsory acquisition, evaluate the adequacy of compensation in mitigating those consequences and assess the sustainability of cash compensation for future generations.Design/methodology/approachA case study approach was operationalised to investigate the experiences of 40 project-affected persons (PAPs) four years after a compulsory acquisition project in Ghana’s New Akrade-Mpakadan region for the construction of a railway line. These perspectives were analysed through descriptive statistics and thematic analyses using the NVivo software. Figures and a holistic framework were adopted to report the identified issues.FindingsOverall, only 25% of PAPs received formal communication prior to the acquisition, and only 10.3% have been fully compensated four years later. Despite the acquiring body initiating the marking of properties and compensation assessment in 2019, no payments were made until 2021. This induced emotional responses of distress, loss, uncertainty, stress and sadness, which was further exacerbated by feelings of hopelessness because there was no platform to voice concerns or pursue arbitration. Although PAPs were only offered compensation in the form of single monetary payments, a third would have preferred re-settlement.Research limitations/implicationsBy exploring the emotional and psychological effects of compulsory land acquisition, the study adds a new dimension to understanding its consequences. This may spark more interest, debate and discourse amongst researchers and policymakers and lead to the creation or enhancement of existing policy and legal measures to address the needs of PAPs in compulsory acquisition projects in developing countries.Originality/valueThe financial consequences of eminent domain are well documented, but this study explored the psychological, emotional and equity implications of the practice under conditions of weak regulatory frameworks. The adequacy of single lump-sum compensations was also explored to highlight preferred alternatives to ensure fairness for generations unborn.

Axial Green Function Method in an Efficient Projection Scheme for Incompressible Navier–Stokes Flow in Arbitrary Domains

We introduce a new approach to solving incompressible Navier–Stokes flow. This method combines a projection scheme with the Axial Green Function Method (AGM). Based on the Kim and Moin methods, our methodology employs a predictor–corrector mechanism to achieve stable and accurate velocity corrections. Using axial Green functions, we transform complex differential equations into simpler one-dimensional integral equations. These are strategically placed along a minimal axis-parallel lines, known as axial lines, within the flow domain. This transformation makes computation and analysis more efficient from a numerical viewpoint. A significant innovation in our approach is using one-dimensional axial Green functions tailored explicitly for the reaction–diffusion ordinary differential operator. These functions efficiently handle the discrete-time derivative and viscous terms of the momentum equation. Furthermore, our approach allows for the arbitrary construction of axis-parallel lines, facilitating analysis near critical flow regions and even enabling the random distribution of these lines. We validate our proposed method through numerical examples, demonstrating the convergence of numerical solutions, the effectiveness of arbitrarily constructed axis-parallel lines, and the potential extension of our method to three-dimensional flow problems. Additionally, this study provides a robust and adaptable alternative way to solve incompressible Navier–Stokes flows, proving its effectiveness in practical applications such as Tesla valves.

Construction and Identification of a Human Colorectal Adenoma Epithelial Cell Line by SV40 Large T-Antigen Transfection.

Colorectal adenoma represents the critical step in the development of colorectal cancer. The establishment of an immortalized epithelial cell line of colorectal adenoma of human origin would provide a tool for studying the mechanism of precancerous lesions, screening the efficacy of novel drugs, and constructing in vivo disease models. Currently, there is no commercially available stable supply of epithelial cells from precancerous lesions. This study aimed to establish a natural LHPP low-expressing precancerous epithelial cell line by SV40-LT antigen gene transfection. Simian vacuolating virus 40(SV40), SV40-LT overexpressed lentivirus vector, was transfected into primary human colorectal adenomatous polyp epithelial cells. The transfected cells were screened, and the screened cells were amplified to obtain the epithelial cell line: IHCRA- CELL. The cells were identified by morphological observation, cell proliferation, Quantitative real-time PCR (qPCR), and Short Tandem Repeats (STR) experiments. Morphologically, the cells showed epithelial-like characteristics, such as polygon shape, desmosomes mitochondria, and strong positive keratin staining. There was no significant difference between the transfected cells and the primary cells. Through the STR identification experiment, no matching cell lines were found in the cell lines retrieval. We successfully established a natural LHPP low-expressing precancerous epithelial cell line by SV40-LT antigen gene transfection, which has been patented and is now preserved in the Chinese Typical Culture Preservation Center. It was verified that the transformed cells maintained the phenotype and biological characteristics of epithelial cells. This cell line can be used to study the mechanism of precancerous lesions, screen the efficacy of novel drugs, and construct in vivo disease models.

Jalur Kereta Api dan Perkembangan Kota Lumajang Pada Masa Kolonial Hindia Belanda, 1893-1942

This research aims to examine the changes in the Afdeeling Lumajang area from a traditional city to a modern city marked by the construction of the Klakah-Pasirian railway line, which was intended as a means of transportation for goods and passengers. Historical methods are used to explain this study. The research results show that the development of the Afdeeling Lumajang area into a modern city was initially influenced by the development of railway transportation facilities for plantation purposes and passenger transportation from inland areas. The Klakah-Pasirian Railway began operating on May 16, 1896, with a train track length of 36 km using the standard rail width used in the Dutch East Indies, namely 1,067 mm. There are nine stops and stations on the Klakah-Pasirian railway line, consisting of Klakah Station, Grobogan Stop, Sukodono Stop, Lumajang Station, Labruk Stop, Tempeh Stop, Mujur Stop, Condro Stop, and Pasirian Station.

Persulfidation and phosphorylation of transcription factor SlWRKY6 differentially regulate tomato fruit ripening.

Cysteine desulfhydrase catalyses the generation of the signaling molecule hydrogen sulfide (H2S) in plants. In this study, we found that H2S can inhibit tomato (Solanum lycopersicum) fruit ripening and SlWRKY6 undergoes differential protein persulfidation in SlLCD1-overexpressing leaves. Then, further study indicated that SlWRKY6 could be persulfidated by H2S at Cys396. By construction of slwrky6 mutants and SlWRKY6-OE lines, we found that SlWRKY6 positively regulates leaf senescence and fruit ripening by activating the transcription of ripening-related genes STAYGREEN 1 (SlSGR1) and Senescence-Associated Gene 12 (SlSAG12). In addition, SlWRKY6 interacted with kinase SlMAPK4 and was phosphorylated at Ser33. Dual-luciferase transient expression assays and electrophoretic mobility shift assays indicated that SlWRKY6 persulfidation attenuated its transcriptional regulation of target genes SlSGR1 and SlSAG12, whereas SlWRKY6 phosphorylation by SlMAPK4 activated the transcription of target genes to promote fruit ripening. Moreover, we provided evidence that SlWRKY6 persulfidation attenuated its SlMAPK4-mediated phosphorylation to inhibit tomato fruit ripening. By transient expression of SlWRKY6, SlWRKY6C396A, SlWRKY6S33A, and SlWRKY6S33D in slwrky6 fruits, we found that SlWRKY6 persulfidation attenuated the expression of SlSGR1 and SlSAG12 thereby delaying tomato fruit ripening, while SlWRKY6 phosphorylation increased the expression of target genes. As tomato fruits ripened, endogenous H2S production decreased, while SlMAPK4 expression increased. Therefore, our findings reveal a model in which SlWRKY6 persulfidation due to higher endogenous H2S levels in un-ripened fruit inhibits its ability to activate SlSGR1 and SlSAG12 expression, while SlWRKY6 phosphorylation by SlMAPK4 activates its transcriptional activity, thereby promoting tomato fruit ripening.

СЕВЕРО-СИБИРСКАЯ ЖЕЛЕЗНОДОРОЖНАЯ МАГИСТРАЛЬ: ИСТОКИ ЗАРОЖДЕНИЯ ИДЕИ

The paper, based on identified historical documents, presents aspects of the origin of the idea of building the North Siberian Railway. The purpose of the study is outlined - to reveal the features of the promotion of plans for the construction of new railway lines at the beginning of the 20th century. The scientific novelty lies in the fact that the work presents unpublished materials, in particular, those stored in the archives of the city of Yeniseisk. Archival documents testify to the results of the meeting on communication routes (Irkutsk, 1906), which laid the foundation for the transformation of railway, river and land transport communications in Siberia. The activities of the authorities of Siberian provinces and cities aimed at developing a network of transport communications are shown. One of the large-scale plans was the idea of building the Northern Highway - Tomsk-Yeniseisk-Kirensk-Amur Road. It was supposed to solve the problems of introducing the entire Northern Region to the common cultural life - from the Ob to the Amur, as well as creating a strong and reliable connection with the Far East. The Russian government supported the idea of Siberian cities, allocating state funds for technical research on the planned Tomsk-Yeniseisk railway line. In 1913, a survey party examined the railway route and put it on the map. However, these plans were not destined to come true at the beginning of the last century, as the time of great upheavals was approaching, which significantly changed all of Russia. At the same time, the focused efforts of researchers of the last century became the basis for the process of accumulating scientific and practical experience, which was necessary for developing concepts for the development of the eastern regions of the country at the beginning of the 21st century.

Scientific support for the design and construction of high-speed railway lines. Chronicle of the Development of Competencies for High-Speed Railway Transport in Russia

The construction of the first high-speed railway in Russia is long overdue. Such a project would be an organic continuation and a new turn in the one and a half century history of Russian railway workers’ struggle to increase train speeds on the country’s railways.
