About this month's discussion topic: Charlotte’s transit system is bigger and more complex than ever. A new light rail line opened in March. Construction continues on the second phase of the Gold Line, or streetcar, linking east and west Charlotte. CATS recently reworked its system of bus routes to help people who don’t need to travel uptown. But the current state and federal governments, which paid for most of the rail projects, are unlikely to support any more significant funding for transit. What is Charlotte’s transit future? Is what we have now as much as we’ll ever get?
