"Streetcars" can run in their own rights of way, essentially its the same technology as light rail. The biggest difference is the capacity, otherwise its essentially the same technology.

There is a clear difference between capacity of light rail and traditional streetcars, but not so much between streetcar technology and light rail technology. They both follow the same basic principles for electrification and modern streetcars are only a tad smaller to allow for in-street operation.
