This editorial discusses commuter rail as a potential solution to ease Atlanta's traffic congestion. It summarizes that commuter rail systems are common in many large cities and a 2007 study proposed a 429 mile commuter rail network for Atlanta serving 55 communities with over 40,000 daily riders. While an initial capital cost was estimated at over $2 billion, commuter rail is cheaper than new rail lines because it uses existing railroad infrastructure. The editorial argues commuter rail merits further exploration and discussion as one part of the region's transportation solutions.
