The building costs of a High Speed Rail line project besides its acquisition, operation and maintenance ones, are very high making it an expensive option of transportation. The implementation of a HSR project must then be evaluated, determining its costs and revenues, in order to justify its viability. This research proposes a model to evaluate the feasibility of a HSR line. The model considers the cases where the demand and the costs have uncertainties, assuming also that the initial evaluated demand can be overestimated. A detailed explanation of the proposed model is given and empirical results for the Brazilian HSR project are discussed. The results show that such a project is a very risky one, and it must be carefully discussed before it becomes a reality.
