Wow!!! You are getting Atlanta an S-Bahn. And trams! New trams! That is bloody brilliant!!

Is that project getting stimulus package funding, or is it funded already?

The loop thing is a London type of idea; Munich or Rhein-Main area S-Bahns all orient towards the centre, and the VRR is polycentric anyway. The Detroit/Flint/Ann Arbor area would need a polycentric layout as well, I guess.-
