Perspectives of territorial development linked to the future high-performance rail lines in Eastern
                   Andalusia.



                       Times theoretically estimated are slightly less than current rail service travel times but future
                   improvements in the existing rail lines and more efficiency in the services and their connections
                   have been considered. The weakness of the eastern connections of Jaen can also be observed
                   due  to  the  limitations  of  the  Linares-Baeza  -  Moreda  rail  line  if  it  is  not  renovated. There
                   probably won’t be direct rail services between Granada and Jaen if this line is not improved,
                   as the travel time is double than that by road, and paradoxically Jaen’s airport is the same as
                   Granada’s.
                   As  has  been  indicated,  another  more  distant  scenario  could  be  considered  regarding  the
                   projections of the national infrastructure plan which foresee a complete number of connections.
                   For this  remote  scenario  around  2050  could  be  estimated  as  the  completion  of the  rest  of
                   connections: The littoral rail line Almería-Motril-Málaga-Algeciras, and the inner connections
                   Granada  –  Motril  and  Guadix-Lorca,  which  will  reduce  these  travel  times  to  Murcia.  The
                   improvement of the line between Linares and Moreda should also be considered.

                   4.     Territorial implications linked to the future High-Performance Rail Lines in
                   Eastern Andalusia.


                          4.1     Territorial effects associated to the passenger flows.

                   With respect to the passenger flows, thanks to the Mediterranean Corridor an extraordinary
                   increase of passenger transport demand from Almeria towards Catalonia is foreseen (they could
                   be multiplied by 20) and even more from Murcia and the Valencian Community (which could be
                   multiplied by more than 300), while the global passenger transport demand in the rest of the
                   Corridor, including our study area, would be multiplied by 2.5 (INECO, 2011). Nevertheless it is
                   probable to consider greater increments in the future scenario.

                   As they have been widely studied in many cases, the main effects associated to the future high-
                   performance rail lines in Eastern Andalusia are linked to the great travel time reductions which
                   are gained, but focused around the stations giving a polarized development model.
                   In the present case these effects will be associated not only with the significant travel time
                   reductions but also to the emergence of new direct relations between the main close cities
                   which now are not connected.

                   With respect to the widespread diversity and dimensions of the territorial effects that need to
                   be covered, in this paper they will be focused on the spatial implications of the inter-urban
                   relations at sub-regional scale.
                   According to other national and foreigner experiences, deeply studied by Prof. J.M. Ureña and
                   his research group, the spatial implications of the new HSR lines can be summarized “in three
                   different processes: changes in functional integration of HSR cities, spatial and urban hierarchy
                   reorganization, and city restructuring” (Ureña et al., 2012, p. 132). Thus the new HSR services
                   will allow the appearance or consolidation of commuting inter-urban relations in one hour, and
                   business, often day return, travel in 2 to 3.5 hours´ travel time, as has been recognized (Ureña
                   et al., 2012, pp. 133-134).
                   In synthesis, as stated by Ureña et al. (2012, p. 140), the inter-urban territorial implications of
                   the new HSR lines are: “Increased metropolitan processes at half and hour’s and one hour’s HSR
                   travel time; re-articulation of medium-sized cities to the system of metropolises; new isolated
                   transportation poles; and collaboration between small, distant cities”. The first one comprises
                   two  processes:  “discontinuous  metropolitan  expansion  at  one  hour’s  HSR  travel  time”,  and
                   “metropolitan reinforcement at half an hour’s HSR travel time”. In addition “there is evidence
                   that  discontinuous  metropolitan  expansion  is  happening  in  small  cities  with  an  HSR  station
