“…In Germany, Ahlfeldt and Fedderson (2009) found that small cities along the KolnFrankfurt HSR corridor saw substantial increases in their Gross Domestic Product compared to other local towns. In Spain, small and intermediate cities on the HSR network, less than one hour (or up to 100 km) away from major metropolitan centers, accrued population growth, thanks to their integration to the larger metropolitan network, which also helped them attract new economic activities and housing investments (Garmendia, Ribalaygua, et al, 2012;Garmendia, Romero, et al, 2012; Ureñ a, Coronado, . For example, some workers now live in Ciudad Real, a small city 50 minutes from Madrid on the HSR line, and commute to Madrid for work (Garmendia et al, 2008).…”
