Rail transport is an industry that has a significant impact on the economy of any country by expanding economic activities, increasing national production, improving and developing the infrastructure of the rail industry. Accordingly, the importance of recognizing the railway industry for more industrial development and competition with developed countries has made us aware of the attitudes, social behaviors and personalities of consumers by using appropriate strategies to reduce cognitive inconsistencies and change attitudes. Consumers took advantage of rail transportation and increased the capacity of the industry. Therefore, the purpose of this study is to design a model to change the attitude of consumers of rail transport services with emphasis on the theory of cognitive inconsistency. The method of this research is a combination of qualitative and quantitative. In the qualitative part, the semi-structured interview method with the help of experts and in the quantitative part, the paired questionnaire method and its distribution among the statistical population of the rail transport industry have been used. In qualitative research, by performing the thematic coding method (theme), the theoretical model was reached and then effective variables were calculated through Demetel and fuzzy ANP methods. They are variables of environmental factors.

Boosting Trade Speed which caused by Exact Wagon Tracking, In One Hand Acquire Customer Satisfaction in Supply Chain and in Other Hand Result in Decreasing Capital Cost and Increasing Productivity then Finally Make Railways Investment justified. We Aim to introducing The Current Procedure in Fleet Tracing, Advantage and Disadvantage of Each Methods, Calculate the Cost and Effect of Humane Errors, Necessity of Implementing Modern Methods for Wagon Tracking and Eventually Determine the Best System of Wagon Tracing in IRI Railway Network by means of Concordance Analysis Approach. For This Purpose, We measured Five Options in Twelve Criteria’s. It is Necessary to Mention that This Research in Context of Automatic Wagon Identification is Novel in the Country and yet not to be done. The Output of The Study Show That Installing the GPS Module on Each Wagon is the Best Method for Wagon Automatic Identification in Iran Railway Network.

The purpose of this study was to investigate the factors affecting the increase in demand in the rail and road system. For analyzing the data, panel data econometric models were used in this study using Eviews software. The research domain includes the province of Semnan in the rail and road transport axes, and the time domain of research based on the passenger displaced annually includes related variables from 90-94 years. In the rail transport network, all factors have a significant effect on passenger traffic, but the effect of employment rates is higher than other factors. Also, the results of the research show that in the road transport network, all factors have a significant effect on the movement of passengers, but the effect of population size is higher than other factors. according to the results, it is recommended to pay more attention to the structure of rail passenger transport companies Because these companies are mostly semi-public and monopolies that are already paying for fuel and the like, they create a safe margin for these companies. And in the long run, monopoly profits, employment efficiency. In order to improve the passenger transportation conditions, considering the fare price, it is suggested that the country's road network, taking into account subsidies and providing special services to owners of heavy passenger cars, take the action of fares and the rail network also extends from the scope. A wider range of train types with varying degrees of quality with Considering the economic conditions of the social strata Exploit.

In this thesis, we tried to study the patterns of rail transportation development in European and Asian countries, taking into account the development criteria of the rail network in our country and no matter of political, ethnic and taste orientations, taking into account the potential of provincial development and increasing the transit of international goods based on upstream documents regarding the prioritization of the planning and executive projects of the Deputy Director of Construction and Development of the country's railways and transparent horizons For development of rail transportation network according to the restrictions of the lead Financial particularly drawn to be placed on the agenda.It is hoped that by considering the scientific research conducted in the field of prioritization of construction projects, we will see a reduction in the duration of projects at the appropriate time considered in the studies Due to the lack of funds and financial resources, as well as the appropriate time of productivity and operation of projects under construction, they must be prioritized..

One of the most important underlying factors for the development of any country is the existence of an efficient and appropriate network to meet the transportation needs of that country. Rail transport plays an important role in the economic development of a country; therefore, the evaluation of rail performance is one of the important issues in the rail transport industry of the country. The main objective of this research is to determine the appropriate model for assessing the performance of the rail transport network of the Islamic Republic of Iran. The present research is a descriptive-analytical research in terms of applied purpose and as a method of implementation. The statistical population of this research includes the railways of the Islamic Republic of Iran. The network data envelopment analysis has been used to assess the performance of the railway areas. Based on the results obtained in 2014, North East 2 ranked first and in 2015 and 2016, the East region was ranked first. In addition, the average efficiency of areas shows that in the period of 2014-2016 the eastern region had the best performance and the northern region had the worst performance.

Rail transit is an important section of rail transport in Iran. Exploiting the potentials of rail transit could have economic benefits for the country; however it seems that the current gains from transit are far behind its potentials. This research uses SWOT analysis to propose a strategic plan for improving Iranian rail transit. We develop a comprehensive list of strengths, weaknesses, opportunities and threats. We ask experts to score the items thereby we can select the most important ones. Making interaction matrices, the competitive strategies (WO) followed by conservative strategies (ST) are determined as the appropriate strategies for Iranian rail transit. Different short term and long term tasks are proposed based on the selected strategies. The tasks include: completion and expanding the rail network along the main corridors; improving the planning and reducing the delays of transit trains; creating a strong and integrated authority to pursue and carry out the transit related tasks.

Today, air and rail transportation are two important industries in the world, because they effect on the economic, cultural and social issues of societies, causing the cities to communicate to each other, and in the larger space, they lead to the relationship between countries. In other words, they lead to the society growth in all economic, cultural and social themes, and sometimes affect the tourism industry negatively or positively. In this research, a simple of Iran provinces have been investigated during the period of 1399-1389. The research method consists of two Granger causation and panel data methods. The results indicate that the relationship between aviation, rail transport and tourism is a one-way relationship, and due to the lack of priority tourism in development plans and the lack of adequate subtraction for airial and railing transportation, subtraction the expectation of direct communication, the results indicate an indirect communication. Also, to measurement of the aviation and rail sectors productivity of the selected provinces it has been used from the input-to-input ratio. According to the obtained results by calculating the average of each province during the period of 1394-1389, in the gross production ratio to the number of rail passengers, Tehran province has the highest measure in the GDP. In the ratio of gross production to rail arrived freight, Tehran province has the highest measure in the GDP. In the ratio of gross domestic product to the number of transported air passengers, Tehran has the highest measure in the GDP and In the ratio of gross production to the air carried freight, Markazi province has the highest measure in the GDP.  

Rail transport industry is one of the growing industries in Iran, and competition in this industry has always increased, and this has led to the recognition of the status of companies active in this area is very important. Each company has one or more competitive advantages that make it superior to its competitors. The quality of services provided by companies can be considered as a competitive advantage for each of them. The purpose of this study was to investigate the factors affecting the quality of service in the railway transportation area and ranking of the companies active in the rail transport of Qom railway station based on these factors. In this research, the hierarchy of criteria was obtained using interpretive structural modeling method, and then their significance was calculated by fuzzy analytic hierarchy process method. Finally, companies have been ranked by the Extended TODIM (an acronym in Portuguese of interactive and multiple attribute decision making) methods, which showed that Fadak company has been selected as the best company in terms of service quality.

Some of the important requirements for developing and developed countries in sustainable development are creating a complete transportation system, systematic, extensive, and efficient pre-emptive impact to environment. Among the aspects of sustainable development, the role of environmental factors has been less noted because of the lack of economic benefits. In addition to natural factors, human factors are the main reasons of environment degradation. The purpose of this paper is to investigate the environmental impact of both rail and road transport system. Emissions of a variety of pollutants by road and rail transportation, consumption of fossil fuels, advantages and disadvantages of each one were used, according to the latest figures published for 2007-2011. Finally, It is determined that rail transport systems consume fewer resources and have less harmful effects on the environment. Therefore, It is more efficient in comparison with road transport system, from sustainable development’s point of view. This was proposed for development of rail infrastructure through liberalization and utilization of more private activities.
