The City of OKC has put out a video explaining everything you wanted to know about streetcar systems (but were afraid to ask):

MAPS 3 Streetcar Presentation - YouTube (http://www.youtube.com/watch?v=lONfVH27x9k)

The presenter/narrator is Mike McAnelly, Senior Transportation Manager of Jacobs Engineering. He's not the most riveting speaker, but it's good solid information on all the technical and practical aspects of building and using modern streetcars. He even delves into TOD (transit oriented design) and the emerging streetcar developments occuring around the country.
