                 4.    A comparison between countries: geography, economy, legal framework and
                 transport


                 This  section  is  split  into  four  subsections.  The  first  one  offers  a  comparison  between  the
                 two countries in terms of the geography and distances between main cities. The second one
                 replicates the same comparison but for the economy of both countries. The third subsection
                 explains the institutional, legal and procurement framework in Spain and Saudi Arabia. The last
                 subsection shows the transport evolution of Spain since the HSR entered into operation and the
                 interurban transport system in Saudi Arabia.
                       4.1     Geography


                 Spain is located in Southwestern Europe, has a population of roughly 47 million people, an
                 increase from 39 million inhabitants in 1992. Despite this, the density is only 92 inhabitants
                 per square km which is quite low compared to other European countries. The majority of the
                 population is sparsely distributed except for two areas: Madrid located in the centre of Spain
                 and along the coast. Moreover, Madrid is 700 metres above sea level, whilst the remaining major
                 cities are at sea level. That makes the profile of the HSR lines more difficult than other European
                 countries where there is no need to serve this natural level difference. Figure 1 provides the
                 HSR network by the end of 2016. The distance between the most important metropolitan areas
                 in Spain (Madrid, Barcelona, Valencia, Seville and Bilbao) is between 400 and 700km, which is
                 believed to be a good distance for the development of HS. That is, lower distances do not justify
                 HSR because of the completion with car, whereas larger distance are very difficult because of
                 the competition with airplanes. Rothengatter (2011) noted that strong competition between
                 air transport and HSR can occur on routes with distance up to 1,000 km, but this is most likely
                 between 400 and 800 km.  Therefore the main transport networks (highway and conventional
                 rail networks) have a radial typology, with the centre on the country’s capital, Madrid. The HSR
                 network follows the same structure, linking Madrid with the most populated cities (Barcelona,
                 Valencia and Seville).
