Seattle's South Lake Union Streetcar began operation in December, 2007.  The 1.3-mile line travels mostly along traffic lanes on city streets.  It connects downtown with the growing South Lake Union neighborhood, passing through the Denny Triangle area along the way.  Proponents hope that it will the first of several local rail routes serving different parts of the city.

There are seven stations in each direction on the line.  The system's fleet consists of three cars, each painted in a different base color: red, orange and purple.  In normal operation two are in service, and one is a spare. 

In this view an inbound run is crossing 7th Ave., close to the downtown terminal at Pacific Place Station.
