The Rapid public transit system wants to find out what an electric streetcar line would cost and how the money could come together.
An advisory committee started meeting last month. Officials plan to build on a 2008 study on the issue.
The original streetcar study envisioned a $79 million, three-mile route mostly along Monroe Avenue between Rapid Central Station and the Sixth Street Bridge.
Grand Rapids in the early 1900s had as many as 70 miles of streetcar lines.
