This story is part of a project on commuting in America.
Cities across the country are investing in old-fashioned streetcars to solve what's known as the "last mile" problem. The hope is that trolleys will make it easier for people to get to their final destination.
Atlanta is one of the latest, laying steel rails for a 2.6 mile line. The tracks will run downtown from Peachtree Street to the Martin Luther King Jr. historic district on the east side of the city. Some see this as a big step forward.
