Evaluation of Rail Infrastructure Investments Related to the New Rail Regulatory Environment in Some Countries

As for any transportation infrastructure project, rail investment projects are subject to appraisals, which traditionally include an economic evaluation to determine public benefits and a financial analysis to determine the purely financial returns. When the company that owns and manages the rail infrastructure, termed the “infrastructure manager,” is legally different from the company that provides the rail service, appraisals are typically carried out separately for the infrastructure manager and the train operator. The appraisal process is different from the process when the same legal entity owns and manages both infrastructure and train operations. The distinction is especially pertinent for European Union member states. This study proposed a comprehensive methodology for rail investment project appraisal for the case of rail infrastructure and train operations that were owned and managed by separate legal entities. The study defined the socioeconomic viability of a project from the infrastructure manager's perspective, which reflected social welfare, as well as the financial viability of the project from the perspectives of the infrastructure manager and the operator. It was recognized that a project would proceed only if the socioeconomic evaluation were positive. In the case of a negative financial appraisal, which was often the case for low-volume rail links, the study demonstrated how the use of subsidies could render the rail investment financially viable. The methodology was applied for a proposed investment in the western extensions of the railway network of Greece project.
