Abstract :The aim of this study is to determine the efficiency values of the Republic of Turkey State Railways (TCDD) in national and international freight transportation between 2010 and 2019. Additionally, the study aims to identify the years in which the company operated more efficiently, process this information, and provide reference years and recommendations to relevant institutions.Since railway investment costs are very high, the efficient use of resources is of great importance. This study is significant in terms of guiding the efficient use of railway resources. Moreover, the use of different input and output variables over a specific time period distinguishes this study from other scientific research, as it incorporates both national and international data. For efficiency measurement, output (tonne-kilometres) and input variables (amount of freight transported, main line length, and number of freight wagons) were used, following the relevant literature. The data used in the research were obtained from the activity reports of TCDD and the Turkish Statistical Institute. DEAP (Data Envelopment Analysis Program) software, based on Productivity Time Analysis, was used to analyze the research data. As a result, the average efficiency in national railway freight transport decreased by 1.8%, while the average efficiency in international railway freight transport decreased by 22.4%. The reference year for both types of transport was 2010. Although efficiency in international railway freight transport showed partial improvement in certain years, it generally exhibited a continuous downward trend.
