“…Railways are environmentally friendly transportation systems, and for this reason, the mode of the railway will be in more demand in the next coming years, since railway CO2 emissions are quite low compared to the road.. Transportation activities are the only sector in the European Union where greenhouse gas emissions have increased since 1990 and road transport emissions account for 25% of total CO2 [7].…”

“…CO2 emission value has increased by rail (diesel). The European Green Deal was developed to reduce emissions by 90% by 2050 and aims to significantly improve the sustainability of transport and promote zero and low emission vehicles and alternative fuels [7]. When the European railway system is studied properly, it is obvious that there are some deficiencies in its infrastructure capacity and quality, and there are also some difficulties in speed and loading due to these deficiencies.…”

The fact that transportation infrastructure has a great impact on economic development reveals the necessity of more economical, comfortable and environmentally friendly transportation between transportation systems. With the rapid development of technology, the importance of the railway transportation system, which can carry high-capacity, economical and safe cargo, in the transportation sector is increasing. Although railway transportation has been used for many years in our country, it is not at the desired level in terms of both freight and passenger transportation. For a more balanced and systematic distribution of transportation infrastructure, transportation systems should be analyzed. In this study, information is given about the development of railway transport in Turkey, its ratio among other types in terms of freight and passenger transport, and its status in railway transport compared to European countries. In line with this information, the deficiencies of the railway and the investments that need to be made have been determined.

Experimental Research of Gaseous Emissions Impact on the Performance of New-Design Cylindrical Multi-Channel Cyclone with Adjustable Half-Rings

Cyclones are widely used for separating particles from gas in energy production objects. The efficiency of conventional centrifugal air cleaning devices ranges from 85 to 90%, but the weakness of many cyclones is the low collection efficiency of particles less than 10 μm in diameter. The novelty of this work is the research of the channel-type treatment device, with few levels adapted for precipitation of fine particulate matter, acting by a centrifugal and filtration principle. Many factors have an impact on cyclone efficiency—humidity, temperature, gas (air) composition, airflow velocity and etc. Many scientists evaluated only the effect of origin and size of PM on cyclone efficiency. The effect of gas (air) composition and temperature, and humidity on the multi-channel cyclone-separator efficiency still demands contributions. Complex theoretical and experimental research on air flow parameters and the efficiency of a cylindrical eight-channel system with adjustable half-rings for removing fine-dispersive particles (<20 μm) was carried out. The impact of air humidity and temperature on air flow, and gaseous smoke components on the removal of wood ashes was analyzed. The dusty gas flow was regulated. During the experiment, the average velocity of the cyclone was 16 m/s, and the temperature was 20–50 °C. The current paper presents experimental research results of wood ash removal in an eight-channel cyclone and theoretical methodology for the calculation of airflow parameters and cyclone effectiveness.

“…In spite of that, an agreed group of drivers has not yet been identified, and the indicators of sustainability fluctuate among companies, projects, and researchers [24][25][26]. Key drivers of sustainability that have been broadly mentioned include the punctuality of rail stations [27][28][29], willingness to pay for maintenance, repair, and operations activity [30][31][32], confidence in the transport authority [33], involvement of the citizens in the construction [34][35][36], and perception of property of infrastructure [37][38][39].…”

A transport business that has reached financial sustainability is one that is providing a service at a price that not only covers its costs but also creates a profit for upcoming contingencies. A focus on rail infrastructure financial sustainability is of paramount importance to guarantee the availability of punctual rail transport to remote potential users. To evaluate the sustainability of mass rapid transit on the relation among hypothetical key aspects of sustainability—perception of property; willingness to pay for maintenance, repair, and operations; confidence in the Roads and Transport Authority; and citizen participation in the rail project—and railway service punctuality, the most important result variable, was studied according to the specialized literature on rail transport sustainability. Leading information was collected by means of personal questionnaires of more than 1000 railway users according to the Krejcie Morgan formula for the calculation of the sample size knowing the population size. Qualitative plus quantitative information was gathered from different ways (technical test of the rail system, discussions with users, focus-group discussions, and interviews with key informers).The outputs by means of the statistical analysis allowed understanding two key perceptions. Firstly, beyond a half decade after construction, during a system intervention, a smaller perception of public property for the railway system was related to better service punctuality. This idea contrasts with the vast majority of the publications, which highlight a regular, direct relationship between perception of property and sustainability of railway systems. Secondly, in spite of three-quarters of users accepting that they would contribute monetarily for maintenance, repair, and operations service, such payments were not imminent because of the lack of confidence in the Roads and Transport Authority. In this situation, more than one-third of the metro stations were identified as non-punctual, beyond a half decade after construction.
