We continue our conversation around public transit, this week focusing on light rail. Light rail often comes in the form of trolleys, tram cars, and street cars, and are generally defined as small, 2-3 car trains on tracks that use electricity for power. 

We look at some of the benefits that advocates of light rail raise when discussing public transit. They argue that light rail can be more efficient, both in costs and in greenhouse gas emissions, than may other forms of transit. They also argue that rail can help trigger revitalization in communities and can encourage investment in areas where light rail is built.
