Serrano, et.al. (2006) suggested that the implications of the HSR in Ciudad Real and Puertollano
should consider the following time scenarios, improving what was prior done/proposed by
Fariña, et.al (2000):
• Before there was any idea of having the new infrastructure.

• When it was known that the new infrastructure will exist but still is not in operation.
• When the new infrastructure is being built.
• Shortly after the new infrastructure was in operation.

• During the first ten years of operation of the new transportation infrastructure.

The aim of this paper is to add another time lapse, 15 more years of operation of the new
infrastructure (up to 25 years since initial operation). This is important because, as Serrano, et.al.
(2006) suggested, research should be aware that the effects of new transport infrastructures on
transport would take place rapidly, while territorial effects will take longer.

Assessing the implications of new transport infrastructures long after their complete
implementation (i.e. 25 years later) has the added problem that other factors mix up with the
new transportation investment, and this exerts greater difficulty to ex-post long-term studies.
Another problem is that data/statistics may change, due to change on collection/elaboration
criteria or even due to collection cancellation.
