Yet Liverpool, even with existing used lines fails to utilize the stations. Project Jennifer in Scotland Road should have been on the Northern Line to give it a station. Unused Dingle underground station should have been the hub of Park Road, but was ignored. New developments should be built around the rail lines to get people off the roads. Merseyrail is considering new smaller Docklands Light Railways trains, that will have higher frequencies to give a hop-on hop-off service.
Atlanta in Georgia is building around its Belt Line track. A track circling the city. It makes common sense to pay to your strengths and use the rail transport infrastructure.
