This article presents the concept of "objective travel time" as a key variable in railway line modernization decision making. The concept tries to achieve a threefold goal: optimization of economic resources, significant presence of the railway in the market share of the corridor, and a positive operational balance. The concept has been successfully applied in the new Rail Investment Program in Spain.
