Louisville has toyed with the idea of bringing back commuter light rail. And some say the infrastructure is already there in Louisville. Here’s a brief history of streetcar and commuter rail transportation in Louisville and the surrounding region. For a great photo archive go to historiclouisville.weebly.com/interurban-elevated-rail.html. Other source material include ‘A Brief History of the Louisville & Nashville Railroad’ by Charles B. Caster & ‘Curious Louisville: Why Did Our Streetcars Go Away? And Can We Bring Them Back?’ By Erica Peterson (WFPL). Send me your thoughts.
