2.1.5 Description of the adopted solution

The alternative with highest score is Case 2.5, which is the adopted solution. The solution has
the following characteristics:
• The configuration results in 30% of double track against 70% of single track.

• The maximum relative travel time is 1.00. This involves a total duration of the journey of
40 minutes between the city centers of Santander and Bilbao.
• It includes 44 daily services, 32 for passengers and 12 for freight. The resulting timetable is
shown in Figure 109.

• This solution also chooses the continuation of the commuter line between Santander and
Liérganes.
• The construction cost of the adopted solution amounts to 1,092.16 million euros, saving
549.02 million euros with respect to a double-track solution (33%), which would cost
1,641.18 million euros.
• Considering a useful life of 40 years and meeting the benefits regarding the social welfare,
the investment becomes profitable starting from the 28th year in operation.
