A July 2015 study by A. Loukaitou-Sideris, D. Peters, and W. Wei of the Mineta Transportation Institute at San Jose State University compared the rail systems of Spain and Germany, and how blended high-speed rail lines have succeeded there. Emphasis was also given to station siting, design, and use. Similarly to Eidlin's study, they found that the best stations not only provided high connectivity, but they also had a broader role by providing shops and services to community members as well as travelers.
