Abstract Rail transit investments require the highest amount of investment costs of all modes. Considering the high cost involved, it is particularly important that their performance justifies this high cost and that expectations from these investments are met. Therefore, in the world, it has become an important field of research to study the gap between the expectations from and outcomes of these investments in order to assess the performances. In Turkey, there is a growing interest in constructing rail transit systems in the cities. However, there has been a limited number of studies on the performance of these investments. It is not clear with what expectations these systems are built or whether these expectations are met. There seems to be an urgent need to study these rail investments, with a particular focus on their planning/investment objectives and outcomes. This paper compares the expectations with the actual outcomes. A sample group was selected among the cities currently operating rail transit systems: İstanbul, Ankara, İzmir and Bursa. Semi-structured interviews were made with the officers and planners that have involved in the planning or implementation phase of the systems. As the primary indicators of performance, cost and ridership forecast and outcome data are collected and considered in the comparison. It is found that systems performed rather poor in terms of expectations, such as attaining ridership forecasts, being built within budget etc. Hence there is a gap between expectations and outcomes.

    Research highlights ►This study opens the way to analyze each system in detail. As mentioned above, there are limited data on the systems. With a study focusing on each system in detail, a scientific data collection would be achieved and this would encourage the ongoing investments to keep required information about the systems in a systematic way. This would help us to evaluate performances of each rail transit system. ►In the scope of the study, the systems in Eskişehir, Antalya, Konya, Adana, Kayseri and Samsun were eliminated either because the systems are under construction or because they are street tramways. A further study can include these systems and an overall analysis considering all rail transit systems can be made for Turkey. ►Another research recommendation is to evaluate, separately and in-depth, different criteria for the systems analyzed in the study. For example, systems’ contribution to city image can be handled as a separate study, with more in-depth analysis of this issue for each city. Similarly, developmental effects, including land-use change, land price change, etc., can be analyzed for each system separately or in comparative approach. Systems’ effects on traffic are also important and can be studied for new systems, collecting before and after data. Such studies would bring out additional results and help to understand the performance of the systems considering a variety of different criteria.
