If the decision-making criterion is to obtain maximum economic profitability (maximum
Economic NPVs) without any additional restriction, as it is for this study case, it is necessary
to analyse in which point (commercial speed) the economic NPVs reaches its maximum.
The maximum economic NPVs corresponds to a certain commercial speed and to a certain
combination of maximum design speed for each sub-section, therefore, this commercial
speed will be the one that maximizes the profitability of the project. For the study case
analysed in this paper the maximum economic profitability is reached at different speeds
depending on the ticket price considered. Below (Table 5), the commercial speed and the
combination of the maximum speed for each sub-section, which maximized the study case
analysed, are shown.
